The four main functions of a computer are input, output, processing, and storage. Input involves entering data through devices like a keyboard or scanner. Output allows users to see and hear processed data through monitors or speakers. Processing is handled by the central processing unit which performs calculations by following instructions in programs. Storage saves data on both a short-term basis in RAM and long-term in devices like hard drives, even when the computer is off.

Four Functions of the Computer
- 1. Four Functions of the Computer
- 2. Input It is the entering or feeding of data or information into a computer. This is done using the keyboard, mouse, or scanner.
- 4. Output Once the data are processed, you can now see, hear, and interact with it. You can see the data in the monitor or hear the sounds through the speaker.
- 6. Processing The central processing unit (CPU) is the part of the computer that handles the data by following a set of instructions called program. microprocessor- carries out complex calculations in less than a second.
- 8. Storage Storage is the component within your computer that allows you to store and access data on a long-term basis. Storage is measured by bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB).
- 9. Two types of Storage •Short term storage refers to random access memory (RAM) which stores information while you are using the computer but it is constantly erased and rewritten as you open and close the files.
- 10. •Long term storage stores and acts as backup even if the power supply is off. .
