Size independent.
The maximum capacity of virtual memory is determined by the address length of the CPU. The actual capacity of virtual memory is determined by the address length of the CPU and the external memory.
When the address length of the CPU is much larger than the external memory capacity, the actual capacity of the virtual memory is the sum of the memory and external memory capacity.
When the external memory capacity is much larger than the CPU word length.
The actual capacity of virtual memory is determined by the CPU word length. In general, the address length of the CPU is larger than the external memory capacity.

Anonymous users2024-02-06Virtual Memory: In the case of a hierarchical memorycomputer systems, the automatic partial loading and partial replacement functions can provide users with a much larger and addressable than physical storage capacityMain memory
Virtual memory. All the programs running in the computer need to go through the memory to execute, and if the programs executed are large or numerous, 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 is necessary to use a relatively large virtual memory, and after the file is read by the memory, it will be stored in the virtual memory first, and after waiting for the memory to store all the files in the virtual memory, the files stored in the virtual memory will be released to the original installation directory.

Anonymous users2024-02-05Note: The virtual memory capacity is generally set to about 5-3 times of the physical memory is the most appropriate, according to the calculation that 1G is equal to Changfan 1024MB, set the appropriate number of virtual memory to the value of hailstorm.
Generally speaking, the size of the initial guess key is equal to the capacity of the memory, for example, the memory is 2G, which is set to 2000MB; The maximum value is 5 times the memory capacity, 3000MB is fine. Virtual memory is also known as virtual memory.
The maximum capacity depends on the CPU address, and the actual capacity depends on the sum of internal and external memory and the CPU address.
Virtual storage was introduced mainly to solve the problem of insufficient memory space. >>>More
The similarity is that they all use the principle of program locality, divide the program into many information blocks, and automatically schedule the information blocks from slow memory to fast memory during operation, and use a certain replacement strategy to improve the hit rate when continuing to run. They use the same address transformation, address mapping method, and substitution algorithm. >>>More
Cache is physical storage The previous memory speed was very slow, so it was very slow when exchanging data with the processing area, which caused the machine to run very slowly, so this thing was born, because the speed of memory reading is relatively fast, so he first put the data in the memory into the cache Cache is very fast, so the processing speed will be accelerated for a long time! Wait until you're done and go back to memory! This solves the bottleneck that greatly affects the processing speed due to the memory transfer speed! >>>More
The purpose of adopting virtual memory is to expand the storage space of the main memory, which is expanded as follows: >>>More
Control Panel System Advanced Performance Settings Advanced Virtual Memory Change You can customize the size of the virtual memory (click on the C drive, enter the size, and click the settings next to it to finish) You can also choose no paging file (that is, you said turn off the virtual memory, not recommended).
