Study Notes
Computer Definition
- A computer is an electronic device that takes input, processes information, stores data, and produces output.
Computer Components
- A computer consists of hardware, software, and firmware components.
- Hardware components include input devices, processing units, storage devices, and output devices.
- Input devices include keyboard, mouse, and scanner.
- Processing units include CPU, ALU, and control unit.
- Storage devices include RAM, ROM, and hard disk.
- Output devices include monitor, printer, and speaker.
Information Processing Cycle
- The information processing cycle consists of four stages: input, processing, storage, and output.
- Input stage involves receiving data from users through input devices.
- Processing stage involves executing instructions and performing calculations using the CPU.
- Storage stage involves storing data and programs in storage devices.
- Output stage involves presenting the results to users through output devices.
