What is the cache memory of a computer? We can interpret it as that allocated size of memory that constitutes a space that occupies a functional role in the performance of the computer, and it has several levels that have not undergone any direct change.
What is cache memory :
A cache memory is a fast-performing memory that acts as an intermediate tool between the CPU and the central memory, both in Computers, phones, or even other electronic equipment, which are used to store certain sets of instructions intended for immediate use in order to speed up performance.
The bottom line is that cache is a chip-based computer component that makes retrieving data from computer memory more efficient. This applies to phones as well.

Cache (cache telephone):
It is the temporary data of any program and this cache or data Temporaries need their own "cache memory".
There are several cache memory in the computer
1- The cache memory of the "CPU"
2- The cache memory of the "RAM"
3- The cache memory of the "hard page file"
The cache memory of the CPU:
The memory size here is a maximum of 64MB, and this size varies according to the processor, and here is the cache or temporary data It is closest to the processor and its processing or execution is the fastest of the Ram and then the Page file.
The cache memory of the RAM:
The size of the memory here is between 2 GB and 32 GB, and this size varies according to the size of the RAM, and here the cache or temporary memory is closer to the second-class processor As for the processing speed, it varies according to the speed of the BUS in the RAM. The speed ranges from 600 to 3200 MHz, and the higher this number is, the faster the data processing and execution speed.
The cache memory of the hard drive:
The size of the memory here is about 2 gigabytes, and here the cache or temporary memory is closer to the third-class processor.
As for the speed of its processing, it is slow Very much by comparing it to the CPU memory and then the RAM memory.
Explanation of the memory cache:
When you open more than one program, let's assume that you open Google Chrome and there are many pages in it, and you also open the Photoshop program with the PES game in the background, as well as the Download Manager program Here, the data of all previous open programs is first stored in RAM, then part of the data stored in RAM is transferred to the CPU memory ..
But if the RAM memory is full due to many open programs, data from those programs is transferred to the page file, here Switching between these programs is slow.
- I do not mean by the word (mobility) moving or copying files, but returning to the program
- Increasing the size of the RAM, for example, from 2 to 8 GB or more It does not increase the speed of movement between programs because the bus or the speed of the RAM is responsible for the speed of movement.
