I just want to know how virtual memory works

Memory plays a big role in a computer, all the programs running in the computer need to go through the memory to execute, if the execution of a large number of programs or a lot, it will cause the memory to be exhausted. In order to solve this problem, virtual memory technology is used in Windows, that is, a part of the hard disk space is used as memory, and when the memory is occupied, the computer will automatically call the hard disk to act as memory to relieve the tension of memory. For example, if the computer only has 128MB of physical memory, when reading a file with a capacity of 200MB, it must use a relatively large virtual memory, and the file will be stored in the virtual memory after being read by the memory, and then the files stored in the virtual memory will be released into the original installation directory.

When running a program, but the actual memory capacity is limited, only some core memory can be reserved, and some threads are only used when needed, so these threads are called into virtual memory, and when they are needed, they will be called into memory.

Most of the processes you see in memory are core processes, and they provide the most basic time that needs to be called at any time, so they remain in memory.

All he tells you is to turn off some unnecessary services. username is the system's and can't be deleted.,Everything else can be deleted.。。

You can also do this under XP by running the msconfig command prompt.

Virtual memory is a folder with hidden properties of the system, which is usually used for memory, but in the case of printing and other situations, it is used to write temporary files, which cannot be replaced. Usually a multiple of the memory, I recommend the maximum, the minimum as large.

Virtual memory is set when Windows uses up the protective memory and causes the system to be unstable, just like Linux swaps.

No, virtual memory is to store a file in the hard disk, when the system memory is not enough, you can use virtual memory.

The above is very detailed.

Regarding the advice not to mess withYou can search for suspicious programs or Google them and make a decision. It is recommended that you disable those services without deleting them yet.

Virtual memory is a memory management technology in Chaqiao computer, with which it can be used as the software needed in daily life, so what is the role of virtual memory, today I will take a look at what the role of virtual memory is.

Virtual Memory FAQ].

Introduction to the role of virtual memory:

1. For each process running in the Windows environment, the operating system will automatically assign them virtual memory space when loading. 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.

Setting up virtual memory can increase your system's page memory usage.

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.

2. The read and write speed of the hard disk is much lower than the real memory, so setting too large virtual memory will affect the speed of your computer.

In general, as long as you check "Automatically manage the paging file size of all drives", the system will automatically adjust the virtual memory size.

In virtual memory, you can call up a job into memory multiple times. When using continuous allocation, a considerable part of the memory space will be temporarily or "permanently" idle, resulting in a serious waste of memory resources, and it is impossible to logically expand the memory capacity. Therefore, the implementation of virtual memory needs to be based on the discretely allocated memory management method.

Virtual memory can be implemented in three ways:

Request paging storage management.

Request segmented storage management.

Request segment paged storage management.

Either way, you need to have a certain amount of hardware to support it.

Its role is basically similar to that of physical memory, but it exists as a "backup force" of physical memory, however, it does not only work when physical memory is not enough, that is, it is possible to use virtual memory when physical memory is enough, and if your virtual memory is set too small, it will prompt "virtual memory is insufficient".

When the memory is not enough, then divide the capacity under the hard disk, and when the memory is used, the speed is not as fast as the real memory, so you set it too big, which will reduce the performance of the computer.

Virtual memory refers to a file created on the local hard disk when your physical memory cannot meet the memory occupation of the application, it can share the pressure of physical memory, if the setting is too large, it will backfire, it is recommended to set it to multiple of the physical memory, Yu, for the sake of me playing so many problems with you, I will put t t in a while

According to Microsoft's recommendations, the minimum value of a virtual memory swap file should be set to a multiple of the memory capacity, but if the memory capacity is 512MB or even 1GB, then it will definitely take up a lot of space. Therefore, when the total memory capacity is less than 256MB, the minimum value of virtual memory is set to multiple; If it is more than 512MB, it is set to half of the memory capacity; Between 256MB and 512MB, it is set to the same value as the memory capacity.

However, in general, the above approach is not recommended - today's software is very memory intensive (especially in 3D).

Recommended configuration: minimum 1024 (may still be small) maximum custom (2G) position, non-system disk.
