The memory capacity of a computer usually refers to the capacity of the random access memory RAM, which is a key parameter of the memory stick. The memory capacity is measured in MB, which can be abbreviated as M. 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 the Random Access Memory (RAM
), which is the key to the memory stick Parameters, the memory capacity is measured in MB, which 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 storageUsually magnetic media or optical disks, such as hard disks, floppy disks, tapes, CDs, etc., can store information for a long time and do not rely on electricity to store information, but are driven by mechanical parts , the speed is much slower than that of the CPU. 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 groups with An integrated circuit with data input and 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.
