Basic Components of a Computer System
- Computer systems consist of four main functions: Input, Process, Output, and Storage.
- Essential components include input devices, system unit (with the motherboard and CPU), output devices, and secondary storage devices.
Input/Output Devices
- I/O devices handle communication between the computer and external entities.
- Input devices capture data for processing, while output devices convey information to users.
System Unit Details
- Contains electronic circuits for processing data.
- The motherboard connects all components, including the processor and memory.
Secondary Storage Devices
- Also known as auxiliary storage, these devices retain data and instructions when not in active use.
- Examples: Hard disk drives, floppy disks, and other forms of external storage.
Central Processing Unit (CPU)
- The CPU is the core component responsible for executing instructions, performing calculations, and managing data.
- Comprised of two main units:
- Control Unit: fetches and decodes instructions, executes tasks.
- Arithmetic Logic Unit (ALU): performs arithmetic and logic operations.
