What is virtual memory on a computer? What does virtual memory mean in a laptop

Virtual memory is the use of disk space to replace it due to the computer's lack of physical memory, which can speed up the running of a program. (You can see the physical memory size in the computer right-click - properties, at the bottom of the regular page, **memory,**is).")

Right-click on the computer -- Properties -- Advanced -- Performance -- Advanced -- (you can see that there is virtual memory in the bottom box) Change -- click on the number in the page file at the top box (that is the current virtual memory size) and select "Custom Size", and fill in the initial size and Maximum value with the virtual memory size you want to adjust.

Generally, the virtual memory is set to be a multiple of the physical memory (if the computer memory is 1g, the initial size is set to 1024, and the maximum value is 2048··· The conversion is: 1GB = 1024MB

If a computer lacks random access memory (RAM) that is required to run a program or operation, Windows compensates with virtual memory.

Virtual memory combines your computer's RAM with the temporary space on your hard drive. When RAM is running slowly, virtual memory moves data from RAM into a space called a "paging file." Moving data in and out of a paging file frees up RAM to get the job done.

Generally speaking, the more RAM a computer has, the faster the program will run. If your computer's speed is slowed down due to a lack of RAM, you can try increasing the virtual memory to compensate. However, computers can read data from RAM much faster than they can from hard drives, so increasing RAM is a better approach.

Right-click on the "My Computer" icon on the desktop and select the "Properties" option in the context menu that appears to open the "System Properties" window. Click on the "Advanced" tab in the window, and a dialog box for advanced settings appears.

Click the "Settings" button in the "Performance" area and select the "Advanced" tab in the "Performance Options" window that appears to open its dialog box.

In this dialog box, you can see the area about virtual memory, click the "Change" button to enter the "Virtual Memory" setting window. Select a partition with a large free capacity, check the box before "Custom size", fill in the specific values in the "Initial size" and "Maximum" columns, then click the "Set OK" button, and finally restart the computer to make the virtual memory settings take effect.

The size of the virtual memory is related to the running speed of the computer, and the network speed has nothing to do with it, you can change it, right-click on my computer - Properties--- Advanced --- point the first setting--- then click Advanced --- then click Change--- change the initial size to 2046 and the maximum value to 4092 points OK.

As the name suggests, virtual memory is the use of a small portion of the capacity of a hard disk as memory. There are many ways to modify it, you can search for it. Change it slightly to a bigger one, and it's OK

This is when the default amount of virtual memory is more than you actually need, and the virtual memory is a space that the computer has created on your hard drive (usually the C drive) to store the system cache.

If you're using XP's system, the solution is simple:

1. Right-click on My Computer and select Properties.

2. In the properties dialog box, select the Advanced tab.

3. In the Performance section (there are these words below: Visuals, Processor Plan, Memory Usage, and Virtual Memory), click the Settings button to open the Performance Options dialog box.

4. In the performance options dialog box, select the advanced column, here you can see that there is a change button in the virtual memory column, and you can also see the amount of virtual memory set by the current system, click the change button.

5. In the custom size, you consider how to set the minimum value and the maximum value according to the remaining space of your computer's hard disk, and after adjustment, if the setting is reasonable, it should not be so easy to have insufficient virtual memory.

Setting example: Suppose your C drive has 5G free space, you can set the minimum 1000 and the maximum 1500

When your computer's physical memory is insufficient, it will borrow a little from the hard disk to use it as physical memory, which is called virtual memory! ~

That is, when the physical memory is not enough, the system can use a part of the hard disk as "memory", which is virtual memory, of course, the storage speed is far less fast than the physical memory.

A portion of the space on the hard disk is used for caching. The size is proportional to your physical memory. It was determined when the system was installed, but it can also be adjusted manually.

The memory settings are mainly set according to the size of your memory and the purpose of your computer. The so-called virtual memory is to use a part of the hard disk space as memory when your physical memory is not enough, but because the speed of hard disk transfer is much slower than the memory transfer speed, the use of virtual memory is slower than physical memory. The value that the individual actually needs should be adjusted many times by himself.

If you set it too much, it will cause a lot of debris, which will seriously affect the speed of the system, and if it is too small, it will not be enough, so the system will prompt you that the virtual memory is too small.

All the programs running in the system are submitted to the CPU through memory before they are executed, but if the executed programs take up a lot of memory or a large amount of memory, it will lead to memory exhaustion. In order to solve the problem of internal exhaustion, the Windows operating system uses virtual memory technology, which simply means that a part of the hard disk space is used as memory, although the hard disk is far less fast in reading and writing than the speed of memory modules. However, it can effectively avoid the problem of system crash caused by memory exhaustion.

However, when running large or some or memory-eating software programs, there may be a shortage of virtual memory.

2. How do I set up virtual memory? Set the size of the virtual memory.

1.Right-click on the My Computer icon to adjust the properties to the System Properties window.

Or just find the control panel in the Start menu and open it"system"Double-clicking to open it has the same effect.

After selecting it, you will see a virtual memory at the bottom, and a button to change (c) at the bottom.

4.After opening the settings, the virtual memory memory window will pop up.

By default, the system sets the virtual memory on the system disk (generally the system disk is installed on the C disk, and some are not installed on the C disk).

Select the drive letter for the C drive, then select the unpaginated file as shown, and then select the settings button as shown. This setting only sets the virtual memory of the system disk to none by default.

5.After setting the virtual memory of the system disk to none, you need to set the virtual memory to a different disk.

After selecting the D disk, select the single item of custom size (c), and fill in the initial size text box: 2048 This 2048 is according to your own memory. Generally, people now use 2G memory, which is 2048MB of memory.

If you are 4g, fill in 2048. It is best to have the same memory size as yourself.

The maximum value is recommended to be a multiple to 2 times the initial size.

After that, the system can be restarted.

It is used as memory when the physical memory is running out, and there is also data that needs to be exchanged with the hard disk to store here.

When the computer is low on memory, it will automatically call the virtual one.
