Study Notes
Internal Hardware Devices
- Processor: Situated on the motherboard, interprets and executes commands from hardware and software
- Motherboard: Houses the processor and connects other internal components
- RAM (Random Access Memory): Internal chip for temporary data storage, contents lost when power is off
- ROM (Read-Only Memory): Stores permanent information, contains configuration data and the boot file (BIOS)
- Video & Sound Cards: Handle graphics and audio processing
- Internal Hard Disk Drives: Store data permanently
External Hardware Devices
- Monitor: Displays visual output
- Keyboard: Input device for typing
- Mouse: Input device for navigation
- Printer: Output device for printing
- External Storage Devices: Portable storage options
Software
- Definition: Programs that control the computer system and process data
- Types of Software:
- System Software: Enables hardware to function correctly, provides a platform for application software
- Examples: Operating systems, device drivers, compilers
- Application Software: Allows users to perform specific tasks
- Examples: Spreadsheets, databases, word processing
- System Software: Enables hardware to function correctly, provides a platform for application software
Analogue and Digital Data
- Analog Data: Represented by physical quantities, varies smoothly (e.g., sound waves, temperature, voltage)
- Analog Devices: Measure, manipulate, and work with analog signals (e.g., analog thermometers, vinyl records, analog clocks)
- Digital Data: Discrete, represented using binary digits (0 and 1), understood by computers
- Digital Devices: Work with digital data (e.g., digital cameras, smartphones, digital watches)
CPU (Central Processing Unit)
- Situated on the motherboard
- Interprets and executes commands from hardware and software
- Components: Control unit, Arithmetic and Logic Unit (ALU), registers
