- Arithmetic Logic Unit: performs
arithmetic and logic operations on data.

- Buses
- Address Bus: carries address of the location
of the memory. Unidirectional.
- Data Bus: carries data between CPU
and memory. Bidirectional.
- Control Bus: carries command signals from control
unit to other components. Bidirectional.

of the memory. Unidirectional.
- Registers
- Provide fast, temporary storage for
instructions and data.

- Clock
- Sends electronic signals at intervals to
components to synchronise all actions.

- Translators
- Compiler
- All code translated prior
to being executed
- All code translated prior

- Interpreter
- Each line of code
translated one at a time
- Because the source code is translated
line by line while execution is underway,
so the program runs more slowly
