What are the five major logical components of a computer?

The five major logical components of the computer: 1. Input device, a device that inputs data and information to the computer; 2. Output device, which is the terminal device of the computer hardware system; 3. Memory, the memory unit is actually sequential logic A type of circuit; 4. Calculator, a component in a computer that performs various arithmetic and logical operations; 5. Controller, which 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 motor. The main command device for starting, speed regulating, braking and reversing.

What are the five major logical components of a computer

The five major components of a computer are input devices, output devices, memory, arithmetic units and controllers.

1. Input device: a device that inputs data and information to the computer. It is a bridge between computers and users or other devices. Input devices are one of the main devices for information exchange between users and computer systems. Keyboards, mice, cameras, scanners, light pens, handwriting input tablets, joysticks, voice input devices, etc. are all input devices.

#2. Output device: It is the terminal device of the computer hardware system, used to receive computer data output display, printing, sound, control peripheral device operations, etc. It also expresses various calculation result data or information in the form of numbers, characters, images, sounds, etc. Common output devices include monitors, printers, plotters, image output systems, voice output systems, magnetic recording devices, etc.

#3. Memory: The memory unit is actually a type of sequential logic circuit. According to the type of memory usage, it can be divided into read-only memory (ROM) and random access memory (RAM). The functions of the two are quite different, so their descriptions are also different.

#4. Calculator: A component in a computer that performs various arithmetic and logical operations. The basic operations of the arithmetic unit include 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 shifts, comparisons, and transmissions. It is also called the Arithmetic Logic Unit (ALU).

5. 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 and braking of the motor. and reverse master device.

is composed of program counter, instruction register, instruction decoder, timing generator and operation controller. It is the "decision-making mechanism" that issues commands, that is, completes coordination and Directs the operation of the entire computer system.
