Full information about Hardware Software and Cloud firewalls

Full information hardware firewall software firewall and Cloud firewalls. You have to make the first decision. This is why you want hardware firewalls or software firewalls. A hardware firewall is a real device that is connected to your network. While software firewalls are installed on each of your computers, phones or tablets.

With the cost of increased maintenance, you may have both hardware firewalls and software firewalls at the same time for possible potential penalties.

In this article, you will learn:-

• Hardware firewall


• Software firewall


• Cloud firewall


• Which firewall is best

Hardware firewall

Because the drawbacks of software-based firewall are centered around the status of their disabled network. A hardware solution is a safe option. Hardware firewalls sit directly behind your router. That's why every one packet of data coming from the internet should pass through your gatekeeper before landing on any of your internal drives.

Difference between Hardware and Software

Most of these solutions include far more sophisticated controls than web filtering and basic data scanning. Like most of the IT industry's developments, new hardware firewalls focus on "intelligent" tasks. Instead of relying on the fully listed virus and attacking the vector, analyze large datasets to identify malware and cyber bots based on irregular activities.

Another advantage of the hardware firewall is that they are always running. There is no need to worry about this. That the workstation hosting your solution will crash. Because these devices are designed for 24/7 security, this type of solution requires only the negative monitoring and maintenance level. Hardware firewalls are extremely complex and managing them is not easy.

Software firewall

This software is exaggerated to call a piece of "firewall", installing it on a local hard drive is like the lock on a door compared to an impenetrable wall. When the software is scanned by the data for the dangers of the firewall. The information contained in it passes through your router, network switch and finally your local hard drive.

Once the whole cycle is over. Then the software firewall may prevent risky activities based on blacklisted IP addresses, known malware definitions, and suspicious application requests.

Although these solutions have value, they can not guarantee. It does not spread malware in other systems before scanning each pack of data. Unless they are on the internet at the entrance to your business. And whenever a computer with a firewall is locked, whatever it saves. She is left without any protection.

Cloud Firewall

The most recent, and undoubtedly the best, network perimeter security solution is the "cloud" firewall. These are on-site pieces with a software interface. Which can be remotely managed by certified security professionals.

This means the service model. Which will monitor the performance and security of your network for specialist anomalies, while your team runs on its business as always? There is no need for onsite twist and updates - all this can be done remotely.

You must have heard many experts say that the age of on-site hardware has passed. And everything in the cloud can be done. The next wave of remote administration network can be. But the need for hardware will never end.

Which firewall is best

Now that you know that every kind of firewall is best for you. So you are ready to decide which firewall is right for you. For more information about how to select a firewall on our head for that guide, what type of firewall is best for your network?

Another tool to keep the mind in mind is that you can run both hardware firewalls and software firewalls at the same time. A hardware firewall will not slow down your computer. And it will provide protection to the gaming console and other network devices, as well as provide an AdBlock to the whole house. You can add your own dedicated software to the firewall to provide each computer, tablet or phone content-based security.

Difference between Hardware and Software, Special Classification

Difference between Hardware and Software. That hardware is a physical device capable of performing and performing tasks based on the software. While the software is a group of instructions given to the computer or other hardware to perform a certain task. There is a different difference between hardware and software. And in this tutorial, we will cover them one by one.

Hardware and Software

Hardware and software are essential components of the computer. And so both are dependent on each other. That's why all readers are advised to get the maximum benefit for visiting this tutorial and explain their concepts about the general question of the difference between hardware and software.

In this article, you will learn:-

• Hardware


• Software


• Difference between Hardware and Software

What is Hardware?

Hardware is any physical device. Which is capable of performing tasks and operations on the basis of software. Hardware is made of electronic devices such as transistors. The hardware is tangible and it can be touched in real time. The hardware is that which works on a computer system. Without any hardware, the computer will not do any work.

And the software will have nothing to run near. Meanwhile, hardware and software work together to work. The software tells the hardware, which tasks to do. And how to perform it. It is a combination of software and hardware as well. Who makes a good system.

Difference between Ram and Rom

Hardware can be classified as input devices (mouse/keyboard), output device (monitor), secondary storage device (RAM / ROM), and internal components (ALU, registers). In the computer system, you can see and touch hardware mouse, keyboard, monitor, processor, RAM, hard drive, printer, scanner and anything within the device.

Hardware failure is random. Failure in hardware may be due to poor manufacturing, sudden voltage spike or environmental factors such as temperature variation, dust, and pollution. Once the hardware gets damaged, it can be replaced with new hardware. Or it can be repaired. The hardware is changed or upgraded to make the system faster and better.

Examples of Hardware

• Mouse, Keyboard, Monitor, Printer, USB, CD Drive, RAM, Hard Drive, Joystick, Scanner, DVD, CPU, Motherboard, Etc.

What is Software?

The software is a group of instructions given to the computer to perform some tasks and tasks. Software is an important part of the computer. Which tells the hardware what to do. And how to perform it. It is much easier to change than hardware components. That's why it is called "soft".

The software has been developed by writing instructions in a programming language. And it is not tangible and it can not be touched in real time.

Software failure is systematic. Failure in software may be due to application failure, virus or other bugs. Once the software gets damaged, it can be replaced with its backup copy. The software is upgraded by rearranging the instructions.

There are several types of software, the main software programs that are commonly used are:

application software:
The application software, as its name suggests. It is designed to achieve the needs of a specific user.

system software:
System software allows to control, operate and extend the computer's processing capacity. The system software provides an interface between the hardware and the end user. The system software is required to run machinery and application software.

Examples of Software

Example of application software is as follows. 

• Chrome browser allows browsing websites and the internet. Media Player allows videos and audios to play, Microsoft Word allows for writing documents.

Example of System software is as follows.

• Windows, Android, Drivers, C, C++, Java, Compiler, etc.

6 Special Differences in Ram and Rom, Types of Ram

Difference between Ram and Rom

 

6 Special Differences in Ram and Rom. When we study computers or artificial intelligence machines, often we hear the names of these RAM and ROMs. By the time you are not in IT, it can be very difficult to understand everything. How computers work and stores data even if you are using the device every day. Each computer needs memory to operate and you may have heard of RAM and RAM. You can also know what they are standing for. But answering the question of how RAM and Rome can be different. it's not that easy. Let's analyze both types of memory in detail. To see what they are all about. let's get started!...

In this article, you will learn:-

• Difference between Ram and Rom


• RAM


• ROM

What is RAM?

The full form of RAM is random access memory, it is used to store data. Safe data can be used by the machine randomly.

Data can be arranged in any order so that the data can be easily accessed by the machine.

The use of RAM allows direct access to the machine or computer to use the data so that the programs or apps present in the computer work easily and quickly, this is the reason that the more RAM a mobile or computer has, the faster function Does it

In RAM we can do reading and writing operations.

RAM acts like a volatile memory i.e., when the computer is shut down, then the data is lost in the RAM ie there is nothing to save.

RAM is of two types

• Static RAM 


• Dynamic RAM 

RAM is used for operating systems, processes and programs.

 

What is ROM?

ROM's full form is a read-only memory, the use of ROM is also used to store data. The data stored in it can be read only by machine or computer but can not be changed so it is called read-only memory.

ROM could only have a reading process.

ROM has often a data store data such as when a computer is started, then it starts booting, the information or instructions related to it are safe in the computer's ROM and it is already stored by the company in ROM Which cannot be changed later, can only be read by the computer.

 What is CPU?

ROM is non-volatile memory ie, when the computer system is closed, data is saved in it, which means the data is not deleted if it is closed.

Rome is used for booting because the booting program remains in it.

These can be the following types of PROM, EPROM, and EEPROM.

What is Big Data: Full Information about Big Data

The term "Big Data" has been around for some time. But what does this really mean? There is still much confusion about this. In truth, the concept is constantly evolving and being reconsidered. Because it is the driving force behind many waves of artificial transformation, including artificial intelligence, data science, and the Internet of Things. But what is really Big Data and how is it changing our world?

In this article, you will learn:-

• What is Big Data?


• Features of big data


• How to analyze Big Data?


• What tools are used to analyze big data?

 

What is Big Data?

There is no hard and fast rule about it that a database should be considered "big" for its size data.
Instead, which usually defines big data New technologies and equipment are required to be able to process it.

Because to use large data You need to run several physical or virtual machines that work together in concert to process all of the data at the right time.

To get programs on multiple machines to work together efficiently so that each program can know which components of the data need to be processed.

And then able to bring results from all machines to get an understanding of a large pool of data. Special programming takes.

Because it is usually too fast for programs to use locally stored data instead of a network.
Therefore the distribution of data across the cluster and how those machines are networked together. This is also an important consideration when thinking about big data problems.

Features of Big Data

While the word "big data" is relatively new, the task of collecting and collecting large amounts of information for the final analysis is old.
This concept gained momentum in the early 2000s when industry analyst Doug Lanai clarified the definition of now-mainstream of large data as three verses.

1- Volume:-

Associations gather information from an assortment of sources, including business exchanges, web-based life, and sensor or machine information from the machine. Before, Store it was anything but an issue. Be that as it may, new innovations, (for example, Hadoop) have decreased the weight.

2- Speed:-

Information streams at a phenomenal speed and ought to be managed in an auspicious way. RFID labels, sensors, and savvy metering are kept running in the close continuous need to manage deluges of information.

3- Variety:-

Information comes in a wide range of arrangements - organized in conventional databases, from numerical information to reports, messages, video, sound, stock ticker information and money related exchanges without documents. In SAS, we consider two extra measurements when it discusses substantial information.

4- Variability:-

Notwithstanding rising speed and assortments of information, information stream can be very incongruent with occasional pinnacles. Is there some pattern in web-based life? Overseeing information heap of every day, regular and occasion trigger pinnacles can be testing. Significantly greater unpredictability with unstructured information.

5- Complexity:-

Nowadays information originates from numerous sources, making it hard to connect, coordinate and supplant information over the framework. In any case, it is essential to include or relate connections, chains of importance and numerous information linkages, or your information can be rapidly wild.

How to analyze Big Data?

One of the most famous ways to turn raw data into useful information is known as Map Reduce.
Map Reduce is a method to pick up a large data set and calculate it on multiple computers in parallel. It acts as a model for the program and is often used to refer to the actual implementation of this model.

• In short,
  Map Reduce consists of two parts.
  Sorting and filtering the map function takes data, and puts it inside categories so that it can be analyzed.
  Reducing the function summaries this data by adding them all together. Although Google is largely responsible for research, Map Reduce is now a general term and refers to the general model used by many techniques.

What tools are used to analyze big data?

Perhaps the most influential and established tool for analyzing large data is known as Apache Headop. Apache Hadop is a setting for massive stacking and is of data, and it is completely open source.

Network Topologies

Hadoop can run on commodity hardware, making it easy to use existing data centers or even analysis in MP3. Hadoop is divided into four main parts:

1.  MapReduce, as is the above description, a model for large data processing;


2.  YARN, a platform for Hadoop's resource management and scheduling programming, which will run on the Hadoop infrastructure;


3. Hardp Distributed File System (HDFS), which was designed for a very high total bandwidth, is a set file system;


4.  A normal set of modules and other modules to use.

Other tools are also out. What attracts attention is the Apache Spark The main selling point of SPARC is that it collects a lot of data for ice in memory for protests in Drive. Which can be very fast for any kind of analysis.
Based on the operation, the analyst could see a hundred times faster or more results. Spark can use HDFS. But it's also capable of working with other data stores like Apache Casandra or OpenStack Swift.
Spark is easy to operate on a local machine, it is easy to test and develop.

What year was the Internet Invented and Who Invented?

What year was the Internet Invented and Who Invented? The Internet is a network of many other connected computers which connects any computer in the world through routers and servers. In other words, in order to exchange information, the connection established between two computers through the TCP / IP protocol is called the internet. The Internet is the world's largest network.

What year was the Internet Invented?

In fact, long before technology existed to build the Internet, many scientists had already anticipated the existence of a worldwide network of information. Nikola Tesla played at the beginning of the 1900s with the idea of "world wireless system", and conceived mechanisms, searchable storage systems of books and media in the 1930s and 1940s, such as Paul Olett and Vanessa Bush's visionary Thinkers have Nevertheless, the first practical schematic for the Internet did not come until the beginning of the 1960s, when MIT's JCR Liquidator popularized the idea of a computer's "intergalactic network". Soon after this, computer scientists developed the concept of "packet switching", which is a method for effectively transmitting electronic data that would later become one of the main building blocks of the Internet.



The first working prototype of the Internet came with the creation of ARPANET, or advanced research projects agency network in the late 1960s. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single computer. In the 1970s, scientists Robert Kahn and Winton Serf continued to develop a communication model to develop the Transmission Control Protocol and Internet Protocol, or TCP / IP, which is a communication model that can transmit data between multiple networks. It sets the standard for it. ARPANET adopted TCP / IP on January 1, 1983, and from there the researchers began collecting "Network of Network" which became the modern Internet. The online world took a more recognisable form in 1990 when computer scientist Tim Berners-Lee invented the World Wide Web. While it is often confused with the Internet, the web is actually the most common means of accessing online data in the form of websites and hyperlinks. The web helped popularize the Internet among the public and acted as an important step in developing a large group of information, most of us now access on a daily basis.

 

Who Invented the Internet and which year?

There are many important players in this development of many different communication and technology tools, who do not judge any person with credit for contributing to the invention of the Internet, all of which were so important.

There are many urban legends and so many folklore around the internet. Often, a story is told about the birth of the Internet, which means that it was made in the eyes of either an event or a person.

In 1960s, Dr. ARPANET will be promoted by the JCR Licklider in terms of the worldwide network of computers. In the paper "Man-Computer Symbiosis" published in 1960, Licklider provided a guide to follow decades of computer research. Larry Roberts, ARPANET's chief architect, will give credit to Miller's vision.

One of the main differences between communication before the Internet is that the flow of information with new standards known as Internet Protocol is the concept of packet switching. In the 1960s, the "On Distributed Communications" of Paul Barn and Rand Corporation defined the concept of packet switching as an integral part of the new technology that would become the Internet. The idea of packet switching allows for a system that can route traffic to an area around the field. If there was a problem, the packet would be rooted just around it. What year was the Internet Invented?

The next step in the development of the Internet will be the work of Bob Kahn and Winton Cerf to create TCP / IP in the 1970s. This new standard of rules will enable different types of computers to communicate with different hardware and software platforms despite their differences.

Who Invented Mouse? History of Douglas Engelbart? The mouse is another important tool to communicate with computers. Generally, it is known as a pointing device. It lets you point objects on the screen, clicks on them, and moves them. At present, the mouse is the most popular Pointer Device. Used to create graphics or graphics, as well as to click on a button or menu. With this help, we can use our keyboards without using the keyboard. Can control. Do you know, Who Invented Mouse?

Who Invented Mouse?

 

When Douglas Engelbart invented a computer mouse in 1960, he made it from wood. Angel Burr died in the past, but, in the journey until now, the mouse has crossed all the halves. It has now become wireless too.

 

Let's learn some interesting facts about the computer mouse.

When Douglas Engelbart invented the mouse in 1960, at that time there were computers with large rooms. These machines were filled with data by Punch Card.

In 1963, Bill English created a wooden mouse based on the sketch of Douglas, in which two wheels were used. In 1968, Douglas delivered the first mouse demonstration at the Computer Conference of San Francisco. Who Invented Mouse?

Jack Holly and Bill English were very impressed with this work of Douglas. He designed the first digital mouse based on the same Xerox Park in 1972. There was no need to convert the mouse from analog to digital, it would send the information straight to the computer. For the first time, a mouse was mounted in this mouse.

In 1970, Douglas Engelbart patented the mouse; His name was 45 patents of invention besides the mouse.

Initially, the mouse was known as a 'bug', but it was called a mouse because the size of the mouse developed at the Stanford Research Institute was exactly like the mouse. Who Invented Mouse?

What Is Inverter?

Who Invented Computer?

Twenty years after Douglas's performance, the mouse came in the market in 1981 for use with a ball and two buttons. It was sold with Xerox Star 8010 personal computer. At that time the price of this computer was $ 16,000.

 

• Mouse ball was invented in 1970 by Bill English.

• Microsoft introduced the first mouse launch in 1983.

 

First Wireless Mouse

 

In 1991, Logitech introduced the world's first wireless mouse, in which radio frequency transmission was used.In 2004 the Logitech company launched the first laser mouse market. The speed of this mouse was 20 times more than the optical mouse.The speed of the mouse is counted in Mikey unit. A Mickey is the 200th part of an inch.It is known as the mouse in many languages, including English, Spanish, Italian, German, French and Russian.

History of Douglas Engelbart?

Douglas Engelbart (Doug) did the initial work on not only mouse but also on e-mail, word processing, and teleconferencing. He was born on January 30, 1925, in Portland, near Oregon. His father was Radio Mechanic and mother Housewife. After working in electrical engineering, he worked as a radar technician in World War II. After this, he started working as an electrical engineer in NASA's organization Naka.  Who Invented Mouse?

Attribution

He soon quit his job and went to the University of California at Berkeley for his doctoral degree. He later established his laboratory under the name of the Augmentation Research Center. His laboratory collaborated in the development of ARPANET, which later became the form of the Internet. He got the Lemelson-MIT Award in 1997 and was awarded the National Medal for Technology in 2000 to prepare the foundations of personal computing. Who Invented Mouse?

Network Topology- Ring Topology, Star Topology, Bus Topology

Network Topology

Network Topology- Ring Topology, Star Topology, Tree Topology, Bus Topology. Today, we want to know about network topologies network topology. It is a layout of the network that computer networks are either physical or network connected. So this means that, when a data transfer occurs in a predefined layout, then it is logical. Network Topology

Topology

Topology:-

 

That's the main cable to talk about the first topology here. And many computers are connected to the main cable, this type of topology is known as just topology in this topology. All computers are connected to the main center or the main cable bus data flows in the same direction. It is cost-effective, it is used in small households in your home. It's easy to expand. But it is slow and dependent on the main cable. Which means, if the main cable fails, then all networks will fail to proceed to the next topology. network topology

 

1- Ring Topology:-

Network Topology. These are computers that are connected in the structure of a ring, which is now known as the ring topology in this topology data. The statement that the unity is flowing in the strictest, from here to here, sometimes it can also be on the other side. This type is now known as the double ring topology. It is unaffected by high traffic. It is very cheap to install. But it is prone to failures. This means that if a computer fails from one ring, then all networks will fail. network topology

What Is Voltage Stabilizer And What Is Its Work?

2- Star Topology:-

 

Let's go to the next topology, now it's a hub or switch and all the computers are connected to that central center. This type of topology is known as Star Topology in this topology. There is a dedicated connection for all computers. Which perform very fast. And easily upgrade the hub but the installation cost is high. And the entire topology network is dependent, which means. If the hub fails then all networks will go down. network topology.

 

3- Point to Point Topology:-

 

There are four computers and servers to go to the next topology and the server is connected to everyone. Computers are connected with each other. This type of topology is known in the topology as the topology of the topology. It has an N (N-2) / 2 channel for the device. There are two ways for data transfer that routing.  network topology. Computers or hubs already know all. And there is an algorithm that finds the best and the shortest way to send data. This topology is strong, it is fully connected. And the best example of S ecology and this topology is P2P connections such as UTorrent. network topology.

 

4- Tree Topology:-

 

Now going to the next topology, this is the main bus. And as you can see. That's hubs and in those hubs, computers are connected in star formation. This type of topology is known as tree topology. Because it is a combination of two topologies bus and star topologies. Now it is used in the van. Which means that the wide area network easily expands the nodes. Which means that you can easily add many other devices and Star Networks easily. Maintaining this network is very easy. But this central center is also dependent. This means that if the main bus fails. So all the networks will now fail to move forward in the next topology. network topology.

 

5- Hybrid Topology:-

 

This is the main bus and as you are watching. Topology is a ring topology with a ring topology. And if more than two types of topologies are combined, the ring topology is connected to the central center. Then this type of topology is known as hybrid topology. Which is used to handle large amounts? This topology, if any computer fails. So easy to identify and remove it has improved network performance easily. But on the negative side, it is very expensive.

 

6- Bus Topology:-

 

Network Topology. One approach to consider a transport topology is that the line associated with the majority of the gadgets or hubs in the system resembles a path along which a flag makes a trip so as to discover the hub to which it is to be conveyed. Normally, the link in the transport topology has two end terminals that hose the flag with the goal that it doesn't continue moving from one end of the system to the next. Diverse sorts of transport topology can be alluded to as straight or appropriated transport topology.

 

A straight transport topology suggests that there is only one line related with two unmistakable endpoints. In a dispersed transport topology, there might be more than one direct example associated with the system. Transport topologies are regularly esteemed for their straightforwardness and lower cost of execution. Notwithstanding, one downside is that if the focal line is endangered, the whole system will go down. Additionally, it very well may be hard to investigate these sorts of frameworks, and issues like information flag misfortune can happen with a more drawn out straight link. network topology.

What is Floppy Disk | Major Parts of Floppy Disk Drive

What is Floppy Disk? Major Parts of Floppy Disk Drive. Do you know what is Floppy Disk? There was a time when the floppy disk drive (FDD) was the only primary means. To add data to the computer only then until the CD-ROM drive became more popular. If so, then these FDDs were very important components. For personal computers that too for almost 20 years. A floppy disk was such a storage medium that had a thin and flexible magnetic disk. Within a plastic carrier, it was used much in the 1970s. By early 2000, they had more storage capacity than other storage devices, they gradually replaced it.

Floppy Disk

These floppy disks are a type of magnetic storage medium. In a computer system, in order to read and write data in the floppy disk, you must have a floppy disk drive (FDD) in your computer system. In the past, the use of floppy disks was stored on the computer's operating system. So today I thought why you should be given full information about the definition of a floppy disk to the people. From which you found people to know something about this old Storing device. So start without delay and know.

 

What is Floppy Disk?

 

Floppy Disk is a kind of data storage device. It was first created in 1969, the year in which the Internet was started. It is part of Secondary or External Memory. These magnetic disks are very thin and flexible so they are called floppy disks or diskettes. It is made of a plastic sheet of a mailer and its two and magnetic material is sticking.

Magnetic discs are locked in other plastic jackets and a small part of the magnetic disk is kept open. Floppy disk size used in computers is of 5.25 inches (also called mini floppy) or 3.5 inches (also called micro floppy).

Floppy disks can store data in very small quantities. It used to be used more in the first computer but since the introduction of the CD, its existence was over because it had more storage capacity. All data in the floppy disk is stored in a spherical magnetic plate and from there the entire data is read.

Technical Terms

(A)- Tracks:-

The area of the disk is divided into several balls and given the number. These are called sphere tracks. The number of outermost shells is 0 and it grows inside. This track is just a logical field, not physical.

(B)- TPI (Tracks Per Inch):-

This is the number of tracks per inch that shows the density of the data. The larger the TPI, the more data will be kept.

(C)- Sectors:-

This is the smallest storage unit on the disk. There are several sectors of a track. Each sector is given a number. An index hole is used to identify the first sector. Sectors are given in two ways -

Soft Sectoring: In this, Sector is created by Software. These disks are called soft-sector discs. This is more reliable. Hard Sectoring: There is a hole in it for your identity. Such a disk is called hard-sector disc.

(D)- Clusters:-

This is the smallest unit in the disk that can be given to the file. It has one or more ones at the same time. This is a group of sectors for a specific file and sectors depends on the type of disc.

(E)- FAT (File Allocation Table):-

This table is managed by the operating system, which contains all the available clusters. In FAT, there is information about the location of each cluster and whether it is in use or not, is bad or not. Without FAT the disk cannot be used. A computer also cannot access it because it has the address of the file.

 

Major Parts of Floppy Disk Drive

• 
  

  Let us know about the important parts of this Disk Drive.

  
  

(A)- Read/Write Heads:-

They are located in both parts of a diskette, they move simultaneously in the same assembly. Their heads are not directly opposite, the second is a foam, which is a Fayad that protects it from being written together in every media surfaces. In the same head used for reading and writing, one is to use a second wider head to erase the track. This allows it to write data in a wider "clean slate", with the analog data of the adjacent track without any interfering.

(B)- Drive Motor:-

A very small spindle motor engages the metal hub in the center of the diskette, which spines it into 300 or 360 rotations per minute (RPM).

(C)- Stepper motor:-

This motor assesses the stepped revolutions of a precise number, from which to move into the read/write head assembly, the proper track position. It goes fastened to the read/write head assembly with stepper motor shaft.

(D)- Mechanical from:-

This is a system that opens the levers of the little protective window in the diskette, which allows read/write heads to touch with the dual-sided diskette media. An external button allows the diskette to eject, at a point where the spring-loaded protective window is close in the diskette.

(E)- Circuit Board:-

It contains all the electronics used in reading or writing data, in Diskette, it also handles these things together. It also controls these stepper-motor control circuits, which is used to move read/write heads to each track.

A capacity of a floppy disk

File Transfer: These 3.5-inch floppy disk drives were used as a universal standard. With compression utilities between computers for file transfers, these files used to be compressed. Because 3.5-inch floppy disk drives were standardized, the data could easily be transferred. This technology was incorporated only because of its efficiency and increasing popularity due to its efficiency and reliability. In Apple and UNIX-based systems, it was possible to have file transfers within two different platforms.

Data Storage: Floppy disks were used to back up the important information according to the data storage and backing up. That was the best way at that time. This medium of retaining data is considered to be very efficient. Because at that time it had the highest capacity. Which was 1.44 MB, with cross-platform compatibility?

Software and Drivers: One of the most important applications was the 3.5-inch floppy disks, their distribution of programs and services in which software and driver updates were the main. They were easily used by Floppy Disk. Well, this method is not used anymore. Because now things can easily be downloaded from the Internet easily.

How do we increase the battery backup of this post laptop to all these basic tips today? , Which will help you to get a battery-backed improvement of your laptop and that also gives you some flexibility. So let's know about those basics tips. How to increase the battery backup of a laptop?

How to increase the battery-backup of the laptop?

 

1- Dim the screen:-

One of the most power-drains of your laptop is the screen's backlight. This is the same LCD screen that you see in the form of colors. This is the most effective on your battery backup

By dimpling the screen, you can save 30 minutes or more of the battery. Mostly we use our laptops in places like indoor, home, office or college, and at these places, we do not even need more brightness. So work only with keeping less brightness in these places.
You can set it according to your laptop's brightness settings and set your brightness level to automatic mode so that the brightness automatically adjusts according to the need and illumination. You can also control it with the help of keyboard shortcuts. How to increase the battery backup of a laptop?

 

2- Remove unneeded applications or features:-

 

Do u know? There are many types of features in your laptop, including Wi-Fi, GPS, Bluetooth, Hotspot, Location. Even when you are not using them, these features continue to use your laptop's battery. So do not forget to discontinue or discontinue the features that you are not using. Use these features only when you need it. Now when you're out of Wi-Fi area, turn off your Wi-Fi, otherwise, it will ruin your laptop's battery. Similarly, remove the applications that you do not need.

This will keep your laptop battery backed up, and then you will be able to use your laptop for a long time.

 

3- Turn off automatic updates:-

Yes, automatic updates are not perfect at all for your battery-backup. Often you should have seen whenever any new updates come, it is installed without asking you, so that the battery of your laptop ends very quickly. This is also one of the reasons why the battery does not last long. So install it only if you need it. Turn off automatic updates by going to the Windows Updates Settings so that you will not have any problems ahead, as well as speed up your internet speed.

4- Use Compatible Charger:-

Not using the right charger is also a danger for the battery-backup of your laptop. Most of the people do not know this and they use any charger without thinking, without which the battery-backup gets damaged very soon, and the battery does not last long. There are many chargers in the market, from which you have to take the right charger, while taking the charger, check out its output voltage and find out if its output voltage meets the charger of your laptop, if the output voltage decreases, So it will not be able to fully charge your laptop battery or take a lot of time to charge. And if the Output Voltage is high, then the battery can also have a Short Circuit. That's why you should use the right charger. How to increase the battery backup of a laptop?

 

5- Do not charge again and again:-

Avoid charging your laptop repeatedly. This sounds a bit strange to you, but repeated charging has a great effect on laptop battery backup. Often whenever we use our laptop, we put it on charge. This deteriorates the battery-backup of the laptop. Therefore, while using us, we should not be charging repeatedly. Now whenever you want to use your laptop, firstly charge it once full, and then use it. And do not charge it until you get the warning for battery charging again.

6- Keep the laptop in sleep mode:-

Instead of shutting down the laptop, keep it in sleep mode. Often whenever we suddenly miss any part of our work, we shut down our laptop without having to save some of our necessary files or projects. Because of which we have to start those programs, again and again, we have to repent. As you know, after shutting down, we can not bring those files back again. But if you think that you will settle your work in half an hour, then it is better to shut down the laptop so that you put it in sleep mode. And then you will be able to save them even by completing their remaining tasks. How to increase the battery backup of a laptop?

 

7- More tips for battery-backup:-

 

• While using the Internet, do not open more than one tab.


• Do not leave your laptop overcharging overnight.


• Keep as little as possible, brightness.


• Do not play more games on your laptop.


• If not required, close the background app running in your laptop.


• Turn off the laptop when it gets warmer.


• Use the right charger only.


• Do not work on a lot of files together.


• Do not make the wrong settings in your laptop.


• Only install the correct Drivers.


• Keep junk files clean.


• Uninstall non-workable applications.

What is VPS, by- Tecrv.com

What is VPS?, if you run the Internet and keep a little bit of information about it. So you must have heard something about VPS or Virtual Private Server because it is quite in operation nowadays. If you only know about it and want to know what this is and what is its work. So you have come to the right place. Because in this post we will talk about what is VPS? What is used for it? And how it works, keeping all these questions in mind, let's know the answer to all of these. 

What is VPS?

Friends, VPS i.e. Virtual Private Server is also called Virtual Dedicated Server. So there is nothing to be confused with. As you can see in its name. Virtual is connected in that I am not talking about any physical or real server. Rather here's talking about something that has been created virtually. 

Virtual Private Server is an online service. In which you get almost all control. Just like you get in your computer. And in many VPS servers, you can also use the operating system. This will give you the same flexibility as the Normal Physical server and you will feel like you have a separate server of your own and you can do anything in it.

VPS

But in reality it is not a complete server, it's just a virtual server built from virtualization technology inside a large server. Which is only part of that large server? But its most important thing is that it makes you feel like a normal physical server. Many small virtual servers are created inside such a large physical server. And they are given to different people. And use them all according to their own accord. They are used by most business owners to host their website. Apart from this, it has many uses like if you are working on a big project. And you do not have to create a computer or server separately, you can look at VPS. 

VPS is a very new technology. And it can do quite well in the coming time. Because it is very cheap to build a physical server and we can use it for our own needs.

There are multiple VPSs in one server and each VPS has its own separate operating system and hence every VPS owner gets almost complete control of its.

 

1- What is Virtualization?

In computers or related things, virtualization means. Create a virtual version of something which does not exist in the real. Nowadays we use virtualization to virtually install an operating system. Where we use software like Virtual Box or VM. And create virtual machines. Actual allows virtualization. Running different copies or images of operating systems on our PC Virtualization has been deflected so that precious processing power can be prevented from being wasted. 

 

2- What is Web Hosting or Hosting?

Web Hosting means simple. Take a place on the Internet on which we can keep our website and our website can be accessed from anywhere through the internet. We refer to this place as Web Server. A web server is a computer that is more powerful than our computer and connected to 24 *7 internet. These servers are of different types and we are just talking about one of these types.

 

3- When and why are VPS used?

We can not consider Virtual Private Server as a replacement for Shared hosting because VPS is a powerful and costly Service. We can not use that to host small websites or create a simple blog. Because if we do this then it will become costly to our website and we will not even be able to use its full power. 

• Therefore, there are some criteria to use VPS such as

 

(A)- Having more than one good traffic websites:-

If you have websites with more than one good traffic and hosted on Shared Hosting, then you should definitely try hosting. Because there is a lot of traffic on Shared Hosting, website speed slowly starts slowing down. If you have a very good traffic on the same website, then you should definitely try it once you get the information about VPS.

(B)- To Create a Powerful Web Application:-

If you are a developer and want to create a powerful web application such as a photo editor, For those who use more resources, if you use shared hosting, you may find many problems. So if you ask to make such application then you will recommend VPS only. Apart from these, there may be many reasons for using a VPS. For that, all you need to remember is that VPS is more powerful than hosting, more controllers and more costly too.

 

4- Benefits of VPS:-

• Some benefits are being given below to read them carefully.

(A)- More on Server:-

The biggest thing of VPS is that you get more control over shared hosting. Because in it you can do almost everything according to your own. It is a complete server of the whole, in which all you have to control. Just like you do to your computer. If you have to host the website in it then you have to do all the setup. So you need to have proper information about it. 

(A)- Any operating system you want:-

Another very good thing about VPS is that in this you can choose from the operating system of your choice. In which you get very wide variety, you get many kinds of operating systems such as Windows, Linux Ubuntu, Debian, Mint etc. But in the case of Windows, you would prefer Linux only because security gets very good in Linux.

(C)- Cheap | Less Costly:-

If you want to prefer your own server instead of VPS So let me tell you that it will be quite less costly to hit a whole server and there is no need to worry about the cost of maintenance. If you are thinking about building your own server So you are going to spend a lot on creating and maintaining it. While there is nothing like this in VPS and from the top you can leave it whenever you want.

(D)- More powerful:-

We have talked a lot about it's so no one can say that this is a lot faster than a normal shared server. And as I have told you earlier that you are making a web application using more resources. So you should use VPS. When you are taking VPS service you will also have the option of how to RAM and processor in it. The kind of hardware you choose here, you get the speed of its own.

 

5- Disadvantages of VPS:-

 

Talking about VPS, we will also see many loopholes and shortcomings in this. As if talking about the first deficiency in it, it is that you have to manage everything in it. And if you do not have complete information about it then you will not be able to manage it properly and due to lack of proper management, many servers are hacked. 
Apart from this, if you want to host your own small website. VPS will not be so beneficial for you, so you have to use VPS as a lot of thinking.

 

Friends, I hope you have what VPS gave me. This information would have been liked this Post And what is used for it? Information about this has to be found. Now, if you think that this post can be a work of friends too. So share it with them as well.

What is Hard disk in Computer | hdd and ssd

What is a hard drive?

What is Hard disk in Computer? - Hard disk or HDD is the same thing, it is a physical disk which we use to store all the big small files of our computer. Whenever you save any file on your computer, that file is saved in your computer's hard drive, if you are interested in parts of the computer then you must read the hard drive.

 

Hard disk

The difference between hard disk and RAM is that hard disks are used to store things, but RAM comes in handy to keep things stored in that storage. When we shut down the computer, anything read in RAM gets cleared. But in the HDD the data is not erased even when the computer is switched off. what is hard disk in computer?

 A disk rotates inside the hard disk, the faster the disk rotates, the data can be stored or read as fast as possible. We measure the speed of hard disk rotation in RPM (Revolutions Per Minute). Most of the hard disk is 5400 rpm or 7200 rmp, obviously the 7200 rmp hard disk is faster than 5400 rmp. What is hard disk in computer?

 

1- Why is the hard disk slow?

Whenever we store the data on a hard disk, it is stored in pieces, and many times those pieces move in different parts of the hard disk. When there is more data on our hard disk then our computer has a little difficulty in finding things on the hard disk, due to which it gets slow. What is Hard disk in Computer?

If you have to keep the hard disk fast, then from time to time, defragment your hard disk with your computer's software. By defragment the hard pieces of all files come together rather than at different places, and our computer has no problem finding the files on the hard disk. What is hard disk in computer?

 

2- What are External Hard Drivers?

The External Hard Drivers are exactly like our computer's hard drive from within, just the difference is that external HDD is externally used by USB port on our computer.

Due to the USB connect, External HDD works slightly slower than the internal HDD. The advantage of External HDD is that you can take this with you anyway.

 

3- What is SSD?

The disk rotates in a hard disk, but there is no chip in SSD, no drive revolves in it. Due to no physical rotation drive, the speed of the SSD is that the speed of the Solid State Drive is multiplied by the speed of the HDD. But the problem is that SSD is costly because of its internal texture.

 

SSD

SSD takes less power to run and is fast. Because of this, nowadays all the ultra-books come in SSD. Such as SSD in Apple's Mac-book Air, comes in advance already. What is hard disk in Computer?

 

4- Note:-

Whenever you delete some kind of data from any of the storage devices, it will never be deleted because one of its images is saved on your storage device so that you can accidentally delete the data in case your data is deleted. With the help of any data recovery software, you can take it back again and the same applies in case of a hard drive. The most popular data recovery software is Pandora which can be easily downloaded from its official website. What is hard disk in Computer?

Unit of data storage measurement:-

The smallest unit to measure storage is byte and you can understand them in this way in increasing order.

• 1 KB-1024 Bytes


• 1 MB-1024 KB


• 1 GB-1024 MB


• 1 TB-1024 GB


• 1 PB-1024 TB

 


Thank you for the post ( What is Hard disk in Computer? ). I think you have got to learn something from this post.

How cpu works | How To Work CPU | Classic Computer

How To Work CPU?

How To Work CPU? We were focused on classic computing based on the CPU. Classic computing is essentially the digital computer, almost every computing device on the market today is a classic computer. How To Work CPU? 

Classic computers operate in serial, in other words, as mentioned in the first article in the series, Computing Origins, executing various instructions extremely fast in 'order', but to the average user, it appears to be running them in parallel, meaning multiple instructions at a time. How To Work CPU?  This is due to many hardware and software optimizations to allow for asynchronous operation. 

How to work CPU

By the end of this article the distinction between parallel and asynchronous operation will become clear, but first, let's see how the classic computer works. As a disclaimer, the concepts we will be discussing are an over generalization of computing architecture, but for the sake of getting an abstracted understanding of classic computing, functionality will serve well.

RAM and CPU combination:-

Alright so first let's bring in the central processing unit, the CPU is the brains of the computer. Let's also bring in memory, the RAM, this is where the CPU accesses stored information it needs. How To Work CPU? Now the CPU also has built-in memory, this is called the cache. The cache is considerably smaller than the RAM, with sizes ranging in the order of 32 kilobytes to 8 megabytes. 

The purpose of the cache is to give the CPU the information it needs immediately. The CPU and RAM are separate objects, so when the CPU needs information, it takes time, albeit a very small amount of time to read the data from the memory. This time can add considerable delay to computer operation. With the cache being right on the CPU reduces this time to almost nothing.

The reason why you don't need much cache storage is that it just needs to store little bits of important information that the CPU will need to use soon or has been using a lot of recently. How To WorkCPU? There are various methods implemented to determine what goes on to the cache, what should be kept on the cache and when it should be written back on to the RAM. How To Work CPU? In a typical CPU, there are various levels of cache, each with different read and write times and sizes, for the sake of simplicity we'll assume a single cache for our CPU. 

So now with the basic components out of the way, let's get into how the computer operates. When a CPU executes an instruction there are five basic steps that need to be completed:

(A)- Fetch:-

Get the instruction from the memory and store in the cache in some cases.

(B) Decode:-

Get the appropriate variables needed for the execution of the instruction.

(C) Execute:-

Compute the result of the instruction.

(D) Memory:-

For instructions that require a memory read/ write operation to be done.

(E) Write Back:-

Write the results of the instruction back into memory.

Nearly every instruction goes through the first three and final step, only certain instructions go through the memory steps such as load and stores but for the sake of simplicity, we'll assume every instruction requires all five steps. Now each step takes one clock cycle, this translates to a CPI, clock cycles per instruction, of five. As a note, most modern processors can execute billions of clock cycles per second, for example, a 3.4 gigahertz processor can execute 3.4 billion clock cycles per second. How To Work CPU? Now a CPI of 5 is very inefficient, meaning the resources of the CPU are wasted.

This is why pipelining was introduced, bringing the asynchronous operation into computing. How To Work CPU? Pipelining essentially makes it so each step can be executed in a different clock cycle, translating to 5 instructions per 5 clock cycles, or in other words, one instruction per clock cycle, a CPI of 1. Essentially what pipelining does is take the segmented steps of an instruction and execute them in each clock cycle, since the segmented steps are smaller than the size and less complex than a normal instruction, you can do the steps of other instructions in the same clock cycle.

For example, if a step for one instruction is fetching the data, you could begin decoding another, executing another, etc - since the hardware involved for those steps isn't being blocked. How To Work CPU? Superscalar pipelines add to this performance further. Think of pipelines as a highway, now typical lane in the highway can execute one instruction per clock cycle. With superscalar processors, you add more lanes to the highway, for example, a 2 wide super

What is RAM | How does RAM work in Mobile

What is RAM?

What is RAM? How does RAM work in Mobile? With this word, almost all people using smartphones are familiar when you are going to pick a new mobile, you have the same question in your mind that you should take a mobile with a ram so that you do not face any problems in the mobile. Talking about RAM, this is a computer or mobile device is a very important thing because it makes any device work better if you do not even know, then we are going to tell you what Random Access Memory is and your mobile or computer How much RAM should be there. 

 

RAM

Telling you that the full form of RAM is Random Access Memory, then there is nothing known about the Random Access Memory from its full form, so it will be understood through a simple example. Suppose you are sitting in an office and you need a file to work, and the file is kept in another room when you have to work, you will get that file from another room and keeping it on the desk that file Will start working on. There is a time when you have to do a lot of work together and you will need a lot of files for this, for this extra work, you will also need a big desk to keep more files. When you have to do some work, you will be able to pick up his file from the desk. When you get the job done, then you will put the father in the same room.

 

1- How does RAM work in Mobile?

In the mobile, Random Access Memory also works in a way that is the second room with the file, you can consider the internal memory in which all your files or apps and the desk is the Random Access Memory that you work on, here its work You have to run an app according to your order and run it. It takes a few seconds for an app to open it. This is because the speed of the Random Access Memory is very fast. You can predict that the cost of making 1GB RAM is as much as the 16GB memory card Happens in.

RAM is required to send the Random Access Memory to the file as soon as it is required when you install a game, it is not installed in Random Access Memory, but it is installed in the internal memory of the phone. When you click on that game, it runs on the Random Access Memory memory to run and Random Access Memory starts working. Meanwhile, there is a very rapid exchange of information between the CPU and the Random Access Memory. But when your computer or mobile ram is low and you are running many big app shells, mobile or computer hangs in this situation, it is said that more Random Access Memory is useful for multitasking.

 

2- What is the need to be RAM?

You must have known what Random Access Memory is, and now you will also want to know how much Random Access Memory is necessary. Nowadays, any mobile should have at least 2GB of RAM, because the size of the current app is growing slowly as if talking about Facebook, if it is open then 200 to 300 MB Random Access Memory is spent. Not only facebook but with the size of the app being suspended, their size is also increasing. So if you want to do multitasking in the mobile then there should be at least 2GB of Random Access Memory in mobile, so that the problem of mobile hanging does not come in front.  By the way, you can also look at the 3GB or 4GB smartphones, because now you will be given 2GB but in the future, you will encounter problems in 2GB.

So now you may have known a lot about Random Access Memory, you may have come to know that what Ram is, you have one more thing to tell you that you should buy as much Random Access Memory as possible, because RAM is something that can not be extended later Although the computer has an option to increase the RAM, but this option is not available for mobile, some apps that change the memory of the phone after being root but it will have some advantage Land but mobile first and becomes even slower.
