This article mainly explains "what are the reasons for the lack of virtual memory in computers?" Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let Xiaobian take you to learn "what are the reasons for the lack of virtual memory in computers"!

1. Infection with virus

Some viruses take up a lot of memory space when they break out, causing the system to run out of memory. Hurry up to antivirus, upgrade virus library, and then anti-virus measures to do well!

2. Improper virtual memory settings

Improper setting of virtual memory may also lead to insufficient memory. In general, the virtual memory size is twice the size of physical memory. If it is set too small, it will affect the normal operation of system programs. Resize virtual memory Take WinXP as an example, right-click "My Computer," select "Properties," then in the "Advanced" tab page, click the "Settings" button in the "Performance" box, switch to the "Advanced" tab page, then click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and restart the system after completion.

Virtual memory files are in the system disk by default. For example, the virtual memory file name of WinXP is "pagefile.sys". If the remaining space of the system disk is too small, resulting in insufficient virtual memory, there will also be insufficient memory. The system disk must retain at least 300MB of remaining space, of course, this value depends on the actual needs of the user. Users try not to install various application software in the system disk, ensure that there is enough space for virtual memory files to use, and it is best to place virtual memory files in non-system disks.

3, because the SYSTEM user permissions are not properly set

When an NT kernel-based Windows system boots, the SYSTEM user creates virtual memory files for the system. Some users use NTFS file system for system security, but cancel the permissions of SYSTEM users to "write" and "modify" in the system disk, so that virtual memory files cannot be created for the system, and when running large programs, there will be insufficient memory. The problem is easily solved by re-granting the SYSTEM user write and modify permissions, but this is limited to users using the NTFS file system.

Simply put, under the Windows operating system (Windows 2000/XP) pagefile.sys this file, it is the system page file (that is, we all know the virtual memory file), its size depends on the number of open programs and you originally set the minimum maximum value of the page file, is constantly changing, sometimes only a few tens of M, sometimes up to 600M or more.

At this point, I believe that we have a deeper understanding of "the reasons for the lack of virtual memory in computers," so we may as well actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
