What is the basis for computers to be able to automatically complete calculations or processing processes?
Article Introduction:The basis for computers to automatically complete calculations or processing processes is "stored programs". In the computer, a program written according to a specific problem is stored in the memory, and then the first instruction of the program is executed according to the first address of the stored program in the memory, and then other instructions are executed in the order specified by the program until the program ends; Therefore, stored programs are the basis for computers to automatically control processing.

What are the basic knowledge points of computer network
Article Introduction:Ⅰ. Division of network levels In order to establish computer networks on a larger scale, the International Organization for Standardization (ISO) proposed the "Open System Internet Reference Model" in 1978, which is the famous OSI (Open System Interconnection) model. In addition to the standard OSI seven-layer model, the common network layer divisions include the TCP/IP four-layer protocol. The corresponding relationship between them is as follows: Ⅱ. OSI seven-layer network model, whether it is the OSI seven-layer model or TCP/IP In the four-layer model, each layer must have its own exclusive protocol to complete its own corresponding work and communicate between the upper and lower layers. Let’s start with the detailed description of OSI’s seven-layer model: (1) Physical layer The physical layer is the most basic network structure.

Is a Turing machine a computer?
Article Introduction:The Turing machine is not a computer. It is a theoretical computing model used to describe the basic principles and processes of computing. It was proposed by the British mathematician Alan Turing in the 1930s. The design of the Turing machine is inspired by the process of human mathematical calculations. It is considered one of the theoretical foundations of computers. It consists of an infinitely long paper tape, a read-write head and a series of states. The paper tape is divided into grids, each grid can write a symbol, the read-write head can read and write symbols, and perform state transitions based on the current state and the read symbol.

What is an analog computer?
Article Introduction:Analog computers refer to computers that use a continuously changing analog quantity as the object to be calculated based on the principle of similarity. Analog computers use electronic circuits to form the basic computing component, which is composed of computing components, control components, layout boards, input and output devices, etc. The analog computer is based on parallel computing and has fast calculation speed; and it appropriately combines arithmetic units with fixed functions, so the program is relatively simple, but the flexibility of problem solving is relatively poor.
