What does a computer's memory capacity usually refer to?

The memory capacity of a computer usually refers to the capacity of random access memory (RAM), which is a key parameter of the memory module. The memory capacity is measured in MB and can be abbreviated as M. The memory capacity is generally a multiple of 2, such as 64MB, 128MB, 256MB, etc. Generally speaking, the larger the memory capacity, the better it is for the operation of the system.

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

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

Memory capacity is a key parameter of the memory module. The memory capacity is measured in MB and can be abbreviated as M. The memory capacity is generally a multiple of 2, such as 64MB, 128MB, 256MB, etc. Generally speaking, the larger the memory capacity, the better it is for the operation of the system.

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

Memory: In the computer structure, there is a very important part, which is the memory. Memory is a component used to store programs and data. For computers, only with memory can they have memory functions and ensure normal operation. There are many types of memory, which can be divided into main memory and auxiliary memory according to their uses. Main memory is also called internal memory (referred to as memory), and auxiliary memory is also called external memory (referred to as external memory).

External memory is usually magnetic media or optical disks, such as hard disks, floppy disks, tapes, CDs, etc., which can store information for a long time and does not rely on electricity to store information, but is driven by mechanical parts and is faster than the CPU It seems much slower.

Memory refers to the storage component on the motherboard. It is a component that the CPU communicates directly with and uses to store data. It stores the data and programs currently being used (i.e., being executed). Its physical essence is One or more integrated circuits with data input, output and data storage functions. The memory is only used to temporarily store programs and data. Once the power is turned off or a power outage occurs, the programs and data in it will be lost.
