What is the memory module on the computer used for?

Memory is like a big road, the memory is large, the road is big, the vehicle is fast, the memory is slow, in the same way, the memory is large The computer reflects fast, and the memory is small and the reflection is slow.

Memory refers to internal memory.

Compared to hard disks, his input and output speeds are much faster.

Because he is directly chip integrated circuit storage, and the speed of the current is about the same.

The hard disk is disk storage, which is only 5400 7200 10000 revolutions per minute.

Memory is mainly used to store data temporarily.

For example, the data called in the computer needs to be read from the hard disk, sent to the memory, and then the memory is sent to the CPU

It can also be understood as a cache between memory and CPU, because the ALU (Virtual Register) in the CPU is much faster than the hard disk.

Therefore, memory is needed to communicate between the CPU and the hard disk.

Of course, all external memory such as optical discs and floppy disks use memory as a bridge.

Let's take an example of if you copied something.

In the state that you did not paste or did not save after pasting.

This data is stored in memory temporarily.

There are two parts to memory.

Random Access Memory (RAM).

That is, it is used to store data temporarily, and the data is lost after the power is off.

So if you copy something, and you don't paste it, you won't be able to paste the data you just copied when you start the computer again.

For example, when you play a game, you feel that the computer speed has slowed down just after playing the game, which means that the memory is occupied by the game data.

The speed returns to normal after starting the computer from scratch, which is when the RAM in the memory frees up the data.

The other part is read-only memory (ROM).

He's dead, can't be deleted, and can't overwrite other data.

It is mainly used to store memory manufacturers, models, etc.

Virtual memory is generally used when memory is low.

The system automatically calls up the space on the hard disk to temporarily replace the insufficient memory work.

Since virtual memory uses hard disk space.

The read and write speed of hard drives is much lower than that of real memory.

So setting too much virtual memory will affect the speed of your computer.

And it's best to set up virtual memory on disk partitions that you don't use often.

Because of the less fragmentation of the partitions that are not commonly used, the head reads and writes smoothly and is relatively fast.

It's the memory, plugged into the motherboard, the larger the memory, the better.

For example, the bookcase is a hard drive, and the larger the bookcase, the more books you will keep, but if you want to check the information, you have to take the books in the bookcase to the desk and flip through one, two, three. n Ben. Set up a desk, the more books can be placed on the desk, and the more books can be placed on the desk, the more books will be full, and the desk is like memory.

Some people liken memory to a workbench, where all kinds of tools and materials are brought and made. When it is done, it is put back in the warehouse, and the warehouse is equivalent to a hard disk.

That's probably what it means, the metaphor is not always 100% accurate, but the meaning is pretty much the same.
