- Sends processed data to output devices.
- Has two main parts:
- Arithmetic Logic Unit (ALU): Does math and logic operations like adding, subtracting, and comparing data.
- Control Unit (CU): Coordinates and controls the execution of instructions, manages the flow of data between different parts of the computer.
- Input Unit:
- Takes instructions and data from the outside world.
- Converts them into a form the computer can understand.
- Sends the converted data to the computer for processing.
- Output Unit:
- Receives processed data from the computer.
- Converts it into a readable form for humans.
- Sends the converted data to the outside world.
- Storage Unit:
- Stores:
- Data and instructions needed for processing (received from input devices).
