The computer hardware system usually consists of five basic parts: input devices, output devices, memory, operators and controllers.
1. Input device: transmits data, programs, text symbols, images, sounds and other information to the computer. Commonly used input devices include keyboards, mice, touch screens, digitizers, etc.
2. Output device: print or display the computer's operation results or intermediate results. Commonly used output devices include: monitors, printers, plotters, fax machines, etc.
3. Memory: The memory stores the information received by the input device in the form of binary data into the computer hardware system memory. There are two types of memory, namely internal memory and external memory.
4. Operator: The operator is also called the arithmetic logic unit. It is a device that completes various arithmetic operations and logical operations on a computer. It can perform mathematical operations such as addition, subtraction, multiplication, division, etc. It can also perform comparisons, judgments, searches, logical operations, etc.
5. Controller: The controller is the center for the computer to command and control the work of other parts. Its working process is the same as the human brain commanding and controlling various human organs.
