What Is The Virtual Memory Of A Computer?

What is the virtual memory of a computer? How does virtual memory work? What are the advantages of virtual memory? Friends, in today’s article, we will know, what is the virtual memory of a computer? So friends, read the article completely so that you can fully know about virtual memory.

You might have heard a lot about RAM and ROM memory technically. System and device memory must be good for good work. So in the same way in this article today we will talk about virtual memory.

Hello, friends welcome to all of you once again in Digital Tech Akshay Blog where you get complete information about different digital platforms, computers things, social media, the internet things, make money online.

Computers are all used today and there are many different types of memory that computers have. In addition to these two memory RAM and ROM on the computer also has another memory, we call it virtual memory. So, friends know in detail about virtual memory.

What Is Virtual Memory?:-

Multiprocessing work is always going on in a computer and for this, a lot of RAM is required. Multiprocessing means opening many programs at once. Such as Microsoft Word, File Manager, running any software simultaneously. RAM is used to run various applications and programs on any computer.

Every time we open different programs in the computer system, the space of RAM is filled to run these programs. And sometimes, such a situation comes that the space of RAM that is left completely becomes full due to running these applications.

After that, no programs and software run on the computer. So in such situations, the computer uses virtual memory. Virtual memory is used for the alternative task of RAM in the computer by taking up the hard disk space of the computer.

Virtual memory provides a separate RAM to the computer. Which is completely different from physical RAM. This is different because physical RAM is in the form of a chip in a computer system which is hardware.

And virtual memory is software. So the work of virtual memory is that if there is less RAM space in the system then that deficiency can be bridged by using virtual memory on the computer.

You will know that RAM is limited to every computer. When we open more than one file and application on the computer, then the RAM space is full. For this reason, the speed of the computer system slows down.

At that time, virtual memory sends RAM data to hard-disk space. Due to which the space of RAM starts emptying. And then the computer is able to perform every task better.

How Does Virtual Memory Work?:-

Whenever the RAM space in the computer starts decreasing, then the operating system of the computer checks those applications and files. Which we keep open in our system.

And whatever files and applications are minimized in the system, that is, the user is not working on them at that time but they remain open. So the computer transfers the data of RAM to all of them with the help of paging files in virtual memory.

When data is transferred from physical memory to virtual memory, the OS divides the application programs into page files.

And also adds the address of a fixed number with each page file. So to transfer data, the computer looks at areas of RAM that have not been used recently and copies them to the hard-disk virtual memory.

Every page file is collected by going to a hard disk. This causes our RAM page to be blank. And the application on which the user is currently working in the present is very smooth in a very good way.

With that, the new application also gets easily loaded. So when we open the applications that we have kept minimized. At that time, the OS sends the file address that was transferred to the hard disk virtual memory by copying it back from the hard disk and sending it back to RAM.

So that we can work on that program and application. The OS does not load files from hard disk to RAM until they are needed. This process can increase the size of the RAM in the computer so that while running more than one program on the computer, you can get rid of the problems of low-size RAM.

Virtual memory has been a physical memory of a computer, rather it is such a technique that permits the exclusion of large programs. Which cannot be completely stored in primary memory? Virtual memory is the part of the operating system that helps in completing the RAM work.

And all the applications which were not able to access earlier will now be able to easily do this through this memory.

What Are The Advantages Of Virtual Memory?:-

Virtual memory was created at a time when RAM was quite expensive. And due to limited RAM in the computer, the memory of the computer used to be full. Especially we used to run multiple programs together.

With virtual memory, we can almost double the RAM of our computer. This increases the speed of the computer more than before. And the biggest advantage of this is that programmers can write big programs to make applications.

Because virtual memory is much larger than physical memory. So you can easily run programs of large size on your computer. Because of this region, virtual memory is best for those people.

Those who do not want to upgrade their computer system. That is, does not want to buy new and large-sized RAM. But want to work fast on the computer.

It can be used without interruption by opening more than one application at a time in the system. But there is also a drawback of virtual memory.

Keeping more page files on the hard disk slows down the process of getting those files. Because the compression of accessing data from RAM in RAM takes a lot of time to access data from hard disk. That is why it takes some time to run multiple applications.

Virtual memory is primarily a technique to expand the capacity of RAM for the user. Virtual memory can be used in all large operating systems.

Friends, this is virtual memory that comes in handy after the computer’s RAM is full, in today’s article, what is virtual memory? Go about it If there are any questions, please comment and ask.
