Memory is a Memory device used to store information in modern information technology. Its concept is very broad, there are many levels, in the digital system, as long as can store binary data can be memory; In the integrated circuit, a circuit without physical form with storage function is also called memory, such as RAM, FIFO, etc.; In the system, the storage device with physical form is also called memory, such as memory bar, TF card, etc. All information in a computer, including raw input data, computer programs, intermediate runs, and final runs, is stored in memory. It stores and retrieves information at locations specified by the controller. With the memory, the computer has the memory function, can ensure the normal work. The memory in the computer can be divided into main memory (memory) and auxiliary memory (external memory) according to its purpose. There are also classification methods for external memory and internal memory. External memory is usually magnetic media or CD, etc., which can store information for a long time. The memory is a storage component on the mainboard that stores the data and programs being executed. The memory is only used to store the programs and data temporarily. If the power is turned off or disconnected, data will be lost.
