Study Notes
Hardware Components of a Computer
- A computer system consists of physical parts that can be seen from the outside, including the keyboard, system unit, and monitor.
Elements of a Computing System
- Contemporary computers are based on the von Neumann architecture, which includes:
- Input devices
- Processor (CPU) - control unit, arithmetic and logic unit
- Memory
- Output devices
Operations of Computer Components
- Inputting: entering raw data, instructions, and information into the computer using input devices
- Storing: storing data and instructions in primary memory and secondary storage
- Processing: converting raw data into useful information using the CPU
- Outputting: presenting processed data through output devices
- Controlling: ensuring all basic operations are executed in a right manner and sequence by the control unit
Input Devices
