The basic units of a computer system are:
Input devices: These devices are used to enter data or instructions into a computer system. Examples include a keyboard, mouse, scanner, microphone, and webcam.
Central processing unit (CPU): This is the brain of the computer system that performs most of the processing and calculations. It is responsible for executing instructions and managing the flow of data within the computer.
Memory: Also known as RAM (Random Access Memory), memory is used to store data and instructions that are currently being used by the CPU. It is a volatile type of memory, meaning that it loses its contents when the computer is turned off.
Output devices: These devices display or output data that has been processed by the computer system. Examples include a monitor, printer, speakers, and headphones.
Secondary storage devices: These devices are used to store data and instructions permanently or semi-permanently. Examples include hard drives, solid-state drives, USB drives, and memory cards.
