Document Summary

The main components of a computer (cpu, memory, storage devices, input/output. There are four main computer hardware components that this notes will cover: cpu, memory, storage devices, input/output devices. Collectively, these hardware components make up the computer system. The computer"s central processing unit (cpu) is the portion of a computer that retrieves and executes instructions. The cpu is often simply referred to as the processor. The alu performs arithmetic operations, logic operations, and related operations, according to the program instructions. The cpu is composed of five basic components: ram, registers, buses, the alu, and, the control unit. How cpu (central processing unit) works: creation and development, improvement of the cpu, fetch, decode and, execute the fundamental functions of the cpu, input unit. The input unit provides data to the computer system from the outside. So, basically it links the external environment with the computer.
