What is the main memory in the computer?
This article will explain in detail what the main memory in the computer is, and the editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.
The main memory of computer refers to ROM and RAM. Main memory is an important part of computer hardware. Its function is to store instructions and data. It can be divided into two categories: read-only memory [ROM] and random access memory [RAM].
The main memory of a computer refers to ROM and RAM.
Main memory (Main memory) is referred to as main memory. Is an important part of computer hardware, its function is to store instructions and data, and can be directly randomly accessed by the central processing unit (CPU).
Random access memory (RAM) can both store and read information from the designated unit. Any information stored in the RAM will be lost after a power outage, so the RAM is volatile memory.
Read-only memory (ROM) operates in a non-destructive readout mode and can only read out information that cannot be written. Once the information is written, it is fixed, and even if the power is cut off, the information will not be lost, so it is also called fixed memory. The data stored in ROM is usually written before loading into the whole machine, and can only be read out during the working process of the whole machine, unlike random access memory (RAM), which can quickly and easily rewrite the storage content. The data stored in ROM is stable, and the data stored after power outage will not change, and the structure is simple and easy to use, so it is often used to store a variety of fixed programs and data.
This is the end of this article on "what is the main memory in the computer?" I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, please share it for more people to see.
