What is the purpose and essence of the use of virtual memory?

The purpose of adopting virtual memory is to expand the storage space of the main memory, which is expanded as follows:

Virtual memory is a technology for memory management in computer systems. It makes an application think that it has contiguous usable memory (a contiguous complete address space), when in reality it is usually divided into multiple physical memory fragments, and some are temporarily stored on external disk storage to exchange data when needed. Most operating systems use virtual memory, such as the Windows family's "virtual memory"; Linux's "swap space", etc.

Virtual memory is also known as virtual memory. Programs running on a computer need to be executed through memory, and if the program is executed that takes up a lot of memory or a lot, it will cause the memory to be depleted. To solve this problem, virtual memory technology is used in Windows, that is, a portion of the hard disk space is used as memory usage.

When the memory is depleted, the computer will automatically call the hard disk to act as memory to relieve the strain on memory.

If the computer runs out of order or if there is not enough random access memory (RAM) required for operation, Windows compensates with virtual memory. It combines your computer's RAM with your hard drive's temporary space. When RAM runs slowly, it moves data from RAM into a space called a "paging file".

Moving data into a paging file frees up RAM so you can get the job done. Generally speaking, the more RAM a computer has, the faster the program will run.

If your computer's rate is slowed down due to lack of RAM available space, you can try to compensate by adding virtual memory. However, computers can read data from RAM at a faster rate than from a hard drive, so expanding the RAM capacity (with memory sticks) is the best option.

Hello, it is a pleasure to serve you and give you the following answer: The purpose of virtual storage is to solve the problem of insufficient storage space in computer systems. It can copy data and programs from physical memory to the hard disk so that when the physical memory is low, data and programs can be recovered from the hard disk.

The steps to solve this stalking problem are as follows:1First, virtual storage software needs to be installed in the computer system to be able to copy data and programs from physical memory to the hard disk.

2.Then, you need to set up a virtual memory in the virtual memory software so that you can copy the data and programs in the internal memory of the object to the hard disk. 3.

Finally, you need to set up a virtual memory in the virtual storage software so that you can recover data and programs from the hard drive when the physical memory is low. Personal tip: Using virtual storage can effectively solve the problem of insufficient storage space in a computer system, but before using virtual storage, you need to be familiar with the use of virtual storage software so that you can set up the virtual storage correctly to achieve the best results.
