I. Definition of Computer:
A computer is an electronic device that processes data and performs tasks according to a set of instructions or programs. It can store, retrieve, and process information to produce useful outputs.
II. Parts of a Computer System:
- Monitor: The screen that displays the output from the computer.
- Keyboard: A device used to input text and commands into the computer.
- System Unit: The main part of the computer that houses the processor, memory, and other essential components.
- Mouse: A pointing device used to interact with the computer’s interface.
- Printer: A peripheral that produces a physical copy of digital documents.
- Speakers: Output devices that produce sound from the computer.
III. Categories of the Parts of a Computer:
- Input Devices: Devices used to enter data into the computer. Examples: Keyboard, Mouse.
- Output Devices: Devices that receive and display data from the computer. Examples: Monitor, Printer, Speakers.
- Processing Unit: The central part of the computer where data is processed. Example: System Unit (includes CPU).
- Storage Devices: Devices used to store data. Examples: Hard Drive, Flash Drive.
IV. Description of a Computer as an Input and Output Device:
- Input Device: A computer can receive input through devices like the keyboard and mouse, which allow users to provide data and commands to the computer.
- Output Device: A computer can produce output through devices like the monitor and printer, which display or print the results of the computer’s processing.
