What is virtual memory and what is it used for 50

Virtual memory, which is virtual rather than actual hardware, is set up to meet the operational requirements of the program and expand the available "memory" space.

Here's how to set up the virtual memory:

1.Right-click My Computer and select the Properties command from the context menu to open the System Properties dialog box.

2.Click on the "Performance" option, and in its "Advanced Settings" area, click on the "Virtual Memory" button. The Virtual Memory dialog box is displayed.

3.In the Virtual Memory dialog box, select the appropriate disk and disk partition. It is suggested here:

For hard disk partitions, you should choose one with enough space; For hard drives, you should choose the fastest one. If two hard disks are installed, you can save the Windows virtual memory swap file to the two hard disks separately, but not in two partitions of the same hard disk, which can effectively improve the system's access performance to the virtual memory swap file. For memory settings, select the "User-specified virtual memory settings" radio button, and then set the exact value of the virtual swap file size in the "Minimum" and "Maximum" options, respectively.

4.After the settings are complete, click the "OK" button, save the settings to exit, and restart the Windows system.

Ladies and gentlemen, if you are helping others, you must help them to the end. Saying so much, how can this brother understand.

To put it simply, memory is like a person has a cerebral cortex, which is a temporary memory center. In the computer, it's the one next to the CPU, which is long and narrow, and there are a lot of black chunks on it. That's called physical memory, and virtual memory is used by the operating system to create a place on the hard disk and virtualize it into memory.

Because the physical memory is not enough for the operating system. However, virtual memory cannot be banned just because it is large. The role is not the same.

Don't blindly believe the so-called optimizations on the Internet that ban virtual memory.

01 Virtual memory.

Physical memory can be mitigated.

Insufficient pressure is conducive to improving resource utilization, and virtual memory needs to be set according to its own situation, which can be set to about twice the actual memory.

02 Virtual memory is to use hard disk to simulate memory usage, objectively speaking, if your memory is large enough, virtual memory is not needed. But in fact, this is often not possible. In order to make better and efficient use of memory resources, the operating system usually loads the most commonly used modules into the cache, then puts the commonly used modules into memory, and puts the least commonly used modules into the hard disk that need to be called during operation.

03 The role of virtual memory: Every process running in the Windows environment will automatically assign virtual memory space to them when they are loaded. To put it simply, virtual memory technology is a technology that uses external access devices, such as hard disks, to hold information that is not enough in physical memory.

04 Setting up virtual memory can increase the page memory usage of the system. This page memory (virtual memory) is not comparable to real memory. This is a compromise feature for a small memory system under Windows.

Prevents system crashes when the memory capacity is exhausted.
