TheThree Main parts of a CPU are:
- Control Unit
- Immediate Access Store (IAS)
- Arithmetic And Logic Unit (ALU)
The control unit has three main jobs:
1. It controls and monitors the hardware attached to the system to make sure that the commands given to it by the application software are used. For example, if you send something to print, the control unit will check that the instructions are sent to the printer.
2. It controls the input and output of data so that the signals go to the right place at the right time.
3. It controls the flow of data within the CPU - which is the "Fetch Execute Cycle".
