The general term for the arithmetic controller and internal memory of a microcomputer is "host". In a microcomputer, the three parts of arithmetic unit, controller and memory are the main components of information processing. The arithmetic unit and controller are collectively called CPU (Central Processing Unit), and the CPU and internal memory are collectively called the host computer. This is The core hardware part of the computer system.

The general term for the arithmetic unit controller and internal memory of a microcomputer is "host".
The three parts of arithmetic unit, controller and memory are the main components of information processing and processing.
The arithmetic unit consists of an arithmetic logic unit (ALU), an accumulator, a status register, a general-purpose register group, etc. The basic functions of the Arithmetic Logic Operation Unit (ALU) are the four arithmetic operations of addition, subtraction, multiplication, and division, logical operations such as AND, OR, NOT, and XOR, as well as operations such as shift and complement. When the computer is running, the operations and types of operations of the arithmetic units are determined by the controller. The data processed by the operator comes from the memory; the processed result data is usually sent back to the memory or temporarily stored in the operator.
The controller refers to changing the wiring of the main circuit or control circuit in a predetermined sequence and changing the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor. main command device. Composed of program counter, instruction register, instruction decoder, timing generator and operation controller, it is the "decision-making mechanism" that issues commands, that is, it completes the coordination and command of the operation of the entire computer system.
Memory is a memory component used to store programs and various data information. Memory is a collection of many storage units, arranged in order of unit number. Each unit is composed of a number of binary bits to represent the value stored in the storage unit. This structure is very similar to the structure of an array, so in the VHDL language, an array is usually used to describe the memory.
In microcomputers, the arithmetic unit and controller are collectively called CPU (Central Processing Unit), which is the computing and control core of the computer system and is the core of information processing, The final execution unit where the program runs. 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 CPU and internal memory are collectively called the host.
The host refers to the container (Mainframe) used to place the motherboard and other main components in the computer hardware system. Usually includes CPU, memory, hard disk, optical drive, power supply, and other input and output controllers and interfaces, such as USB controller, graphics card, network card, sound card, etc. Those located inside the main chassis are usually called internal devices, while those located outside the main chassis are usually called peripherals (such as monitors, keyboards, mice, external hard drives, external optical drives, etc.). Usually, the host itself (after installing the software) is already a computer system that can run independently. Computers with special purposes such as servers usually only have the host and no other peripherals.
