Explanation:
- Input Devices – Used to enter data (e.g., keyboard, mouse).
- CPU (Central Processing Unit) – The brain of the computer, which includes:
- Control Unit (CU): Directs operations.
- Arithmetic Logic Unit (ALU): Performs calculations and logic operations.
- Registers: Temporary data storage for quick processing.
- Memory (RAM) – Temporarily holds data for quick access.
- Storage Devices – Used for long-term data storage (e.g., HDD, SSD).
- Output Devices – Displays or prints results (e.g., monitor, printer).
