The basis for a computer to have a strong memory capability is a storage device with sufficient capacity. Memory can be divided into internal memory and external memory. They enable computers to have powerful memory functions and can store large amounts of information. This information includes not only various types of data information, but also programs for processing these data.

The basis for a computer to have a strong memory capability is a storage device with sufficient capacity.
Memory can be divided into internal memory and external memory, which enable computers to have powerful memory functions. External storage is usually magnetic media or optical disks, which can store information for a long time. Memory refers to the storage component on the motherboard, which is used to store data and programs currently being executed, but is only used to temporarily store programs and data. If the power is turned off or the power is turned off, the data will be lost.
Memory is a memory device used to store information in modern information technology. The concept is very broad and has many levels:
In a digital system, anything that can save binary data can be a memory; in an integrated circuit, a memory that does not have a physical form has a storage function The circuit 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 stick, TF card, etc.
All information in the computer, including input raw data, computer programs, intermediate running results and final running results are stored in the memory. It stores and retrieves information based on locations specified by the controller. Only with memory can the computer have memory function and ensure normal operation.
Main features of the computer:
Fast operation speed: The computer is composed of internal circuits that can complete various arithmetic operations at high speed and accurately. The computing speed of today's computer systems has reached trillions of operations per second, and microcomputers can also reach more than 100 million operations per second, enabling a large number of complex scientific computing problems to be solved. For example: the calculation of satellite orbits, calculations of large dams, and 24-hour weather calculations take years or even decades, but in modern society, they can be completed in just a few minutes using computers.
High calculation accuracy: The development of science and technology, especially the development of cutting-edge science and technology, requires highly accurate calculations. The reason why computer-controlled missiles can accurately hit the predetermined target is inseparable from the precise calculation of the computer. A general computer can have more than a dozen or even dozens of (binary) significant digits, and the calculation accuracy can range from a few thousandths to a few millionths, which is beyond the reach of any computing tool.
Strong logical operation capabilities: Computers can not only perform precise calculations, but also have logical operation functions and can compare and judge information. The computer can save the data, programs, intermediate results and final results involved in the calculation, and can automatically execute the next instruction based on the judgment result for the user to call at any time.
Large storage capacity: The memory inside the computer has memory characteristics and can store a large amount of information. This information includes not only various types of data information, but also programs for processing these data.
High degree of automation: Because computers have the ability to store memory and logical judgment, people can incorporate pre-programmed program groups into computer memory. Under program control, the computer can work continuously and automatically without the need for human intervention.
High cost performance: Almost every household will have a computer, which is becoming more and more common and popular. In the 21st century, computers will surely become one of the indispensable electrical appliances for every household. Computers are developing rapidly, including desktops and notebooks.
