In layman s terms, what is memory? Don t go into a long speech, it s mostly in layman s terms

To put it simply, memory is a channel that connects your information input and storage, one end is the operation of your keyboard and mouse, and the other end is your hard disk and other things that store information, memory is just a bridge!

Memory is internal storage, as opposed to external storage. The memory module in your machine is the memory. Hard disks, floppy disks, USB flash drives, optical discs, etc. are all external memory.

If the CPU is the brain.

Memory is the computer's scratch paper, which is thrown away when you use it, and stored things temporarily.

A hard drive is a workbook, and the content can be viewed by others.

Memory is the most direct unit of data transfer to the CPU (and then to other units such as hard disks), and any data transfer has to pass through it, so its role is critical

Memory is the amount of storage on your computer!!

A computer is likened to a factory:

CPU: Worker;

Memory: the place where work is done;

Hard Disk: Warehouse;

Software: Programs that do the work;

Input: your command;

Output: Its product.

A computer is likened to a person;

CPU: the material structure of the brain;

Memory: the brain's temporary memory;

Hard disk: the permanent memory of the brain;

Software: Programs that do the work;

Input: your command;

Output: It works.

Let's put it this way: the hard disk is like a pot, the memory is the bowl, you can't always drink soup with the pot, put the food you want to eat in the bowl before eating.

Let's take a big analogy.

CPU your brain.

Motherboard your skeleton.

Hard disk your brain cells.

Memory your stomach.

The computer is used to store files and applications is the hard disk in your computer, which belongs to external storage, all the files and programs you install and the Windows system, drivers, etc. are placed in the hard disk, the capacity of the hard disk is divided by g, there are 40g, 80g, 120g, 160g, etc., the larger the storage of things! The maximum game in general is more than 4G, so you should be able to install 80G! If your computer is 80G, and a game is 1G, it means that you can install 80 games in your computer, this is an example, the general computer says 80G, and you can't install the game when you have 80G capacity for you, because there is also a Windows system!

It also takes up space on your hard drive! And the "memory" that the computer says refers to the computer's dynamic memory, which belongs to the internal memory! It's a transit point for computer processing programs!

To put it bluntly, when the computer processes a program or command, it first calls up the processed program in the hard disk and puts it in the memory for processing, and the larger the memory, the faster the processing speed! The 512m and 256m and 128m on the hard disk refer to the capacity of the hard disk, which is a unit of capacity! The capacity is divided into b, kb, m, g!

where 1kb = 1024b

1mb=1024kb

1gb=1024mb

Got it! The memory only processes the files sent by the hard disk, so the capacity does not need to be too large, generally 512M to 1G is enough!

1.Computers generally refer to memory modules! Generally, there are 1g, 2g, 4g, 8g, 16g, etc. Mainly used as a transfer station for the CPU to process data, not to store files for a long time (the files disappear after the power is off), all without being as big as a hard disk!

2.Some mobile phones refer to RAM as a computer memory, and some people refer to ROM and computer hard disks for long-term storage of files!

Pool Paged Bytes and Pool Non-Paged Bytes monitor the pool space for all processes on the server. Page file: Windows page file, virtual memory Virtual bytes counter can be passed, lltpxx

Memory is constantly refreshed, such as the CPU cache, and your memory module.

You can think of it as a potential state.

A high potential means 1 and a low potential means 0

So once the power is out.

It doesn't mean anything.

Because of this, it can be read directly without conversion. So it's fast, but the capacity doesn't increase easily. It cannot be persistently stored.

External memory refers to disks, tapes, optical discs, USB flash drives, and other dismantling media. They all rely on magnetism, optical pits, and storable semiconductors, which can be stored without powering on to maintain the medium, so they can store data permanently, but when they read the data, they all need to dismantle the royal banquet.

Photoelectric conversion, or magnetoelectric conversion, requires a conversion process, so the speed is relatively slow compared to the memory of the bank. The capacity can be made relatively large according to the characteristics of the medium, and the data can be stored permanently.

Blindly pursuing large memory does not have much effect on improving speed.

We all know that the speed is directly related to the motherboard, CPU, memory, and hard disk.

Hardware has its speed limit, now the CPU is the fastest relative to other hardware, but we still feel that the computer is too slow, that is because other hardware is slower than the CPU, so the CPU is in the cycle waiting time most of the time, so the speed seen in the CPU performance monitoring is constantly changing.

Relatively large memory is good, under normal circumstances, most of the software or load multiple software memory is still surplus, but it does not mean that the speed has been improved, although there are multiple software in the memory, are consuming memory and CPU resources, in the case of human operation, in fact, only one program (software) can be run at a time, and the others are just temporarily occupying memory resources.

Another computer to maximize the performance of the operating system is also related to the operating system, the operating system manages and controls the hardware, and provides people to control the computer, which is the role of the operating system. If the operating system is not good, it will not be able to give full play to the performance of the hardware, so the operating system is also constantly developing and improving. The Windows series of operating systems is divided into 32-bit version and 64-bit version, the 32-bit version can only manage memory, and the 64-bit version can manage theoretical 128GB memory, but in practice, it is limited by the motherboard, and the personal computer supports up to 16GB memory.

The above is about the hardware and operating system of each computer, and the server hardware and operating system are different.
