💻 Main Functions of a Computer System

All computer systems perform five basic operations to convert raw input data into meaningful information for users:

1. 🖱️ Inputting

• The process of entering data and instructions into the computer system.

• Examples: Keyboard, mouse, scanner, microphone.

2. 💾 Storing

• Saving data and instructions so they are available for initial or future processing.

• Storage can be temporary (RAM) or permanent (hard drive, SSD).

3. 🧮 Processing

• Performing arithmetic or logical operations on data to convert it into meaningful information.

• This is handled by the CPU (Central Processing Unit).

4. 🖥️ Outputting

• Producing useful information or results for the user.

• Examples: Printed reports, visual displays on monitors, audio output.

5. 🎛️ Controlling

• Directing the manner and sequence in which all the above operations are performed.

• Managed by the control unit within the CPU.
