This article mainly introduces what the memory capacity in the computer usually refers to, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it with you.

The memory capacity of a computer usually refers to the capacity of random access memory (RAM), which is the key parameter of the memory bar. The memory capacity is in MB, which can be abbreviated to M. The capacity of memory is generally the integral power of 2, such as 64MB, 128MB, 256MB, etc. Generally speaking, the larger the memory capacity, the more conducive to the operation of the system.

The memory capacity of a computer usually refers to the capacity of random access memory (RAM).

Random access memory (Random Access Memory, abbreviation: RAM), also known as main memory, is an internal memory that exchanges data directly with CPU. It can be read and written at any time (except when refreshed), is fast, and is usually used as a temporary data storage medium for the operating system or other running programs. RAM can write (store) or read (read) information from any specified address at any time while working. The biggest difference between it and ROM is the volatility of data, that is, the data stored in the event of a power outage will be lost. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results.

Memory capacity is a key parameter of memory bars. Memory capacity is measured in MB, which can be abbreviated to M. The capacity of memory is generally the integral power of 2, such as 64MB, 128MB, 256MB, etc. Generally speaking, the larger the memory capacity, the more conducive to the operation of the system.

At present, the mainstream memory capacity of desktop computers is 256MB or 512MB, 64MB memory, 128MB memory has been rarely used. The system recognizes memory in Byte (bytes), and each byte is composed of 8-bit binary numbers, namely 8bit.

Memory: in the structure of a computer, there is a very important part, that is, memory. Memory is a component used to store programs and data. for a computer, only with memory can it have memory function and ensure normal work. There are many kinds of memory, according to its use can be divided into main memory and auxiliary memory, main memory also known as internal memory (referred to as memory), auxiliary memory also known as external memory (external memory).

External memory is usually magnetic media or optical disc, such as hard disk, floppy disk, magnetic tape, CD, etc., which can store information for a long time, and does not rely on electricity to save information, but driven by mechanical parts, the speed is much slower than CPU.

Memory refers to the storage components on the motherboard, which CPU communicates directly with and uses the components to store data. Its physical essence is one or more groups of integrated circuits with data input and output and data storage functions. Memory is only used for temporary storage of programs and data. Once the power is turned off or power outage occurs, the programs and data will be lost.

Thank you for reading this article carefully. I hope the article "what does the amount of memory in a computer usually refer to" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel. more related knowledge is waiting for you to learn!
