What does microcomputer host mean?

Microcomputer host refers to the CPU and memory; the CPU is one of the main equipment of the electronic computer and the core accessory in the computer, while the memory is one of the important components of the computer. It is the external memory that communicates with the CPU. Bridge, all programs in the computer run in memory.

Usually the host of a microcomputer refers to the CPU and memory.

Computer hardware is composed of two parts: host and peripherals. The host part includes CPU and memory.

CPU

Central processing unit (CPU) is one of the main devices of electronic computers and a core accessory in computers. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is the core component of the computer that reads instructions, decodes them, and executes them. The central processing unit mainly consists of two parts, namely the controller and the arithmetic unit, which also include cache memory and the data and control bus that realize the connection between them. The three core components of an electronic computer are the CPU, internal memory, and input/output devices. The main functions of the central processing unit are to process instructions, perform operations, control time, and process data.

In the computer architecture, the CPU is the core hardware unit that controls and allocates all hardware resources of the computer (such as memory, input and output units) and performs general operations. The CPU is the computing and control core of the computer. The operations of all software layers in the computer system will eventually be mapped to CPU operations through the instruction set.

Memory

Memory is one of the important components of the computer. It is the bridge between external memory and CPU. All programs in the computer run in memory. The strength of memory performance affects the overall performance of the computer. Memory is also called internal memory and main memory. It is used to temporarily store operation data in the CPU and exchange data with external memories such as hard disks. As long as the computer starts running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation. When the operation is completed, the CPU transmits the result. The operation of memory also determines the speed of the overall computer operation. The memory stick is composed of memory chips, circuit boards, golden fingers and other parts.
