- Control Unit this part controls the input and output devices.
- Arithmetic Logic Unit this is the part that does all the working out: it does all the maths and makes the
decisions.
- It is also known as microprocessor or processor

- Random access memory
- Memory
- Virtual memory
- V-M
- Only used when the device is lacking R.A.M
- Slower
- Bigger than R.A.M
- Virtual memory is simulated memory that is written to a page file on the hard drive.
- Virtual memory is used by operating system to simulate R.A.M sizes by using hard disk drive.
- Allows us to to run more applications on the system
- The primary benefits of virtual memory include freeing applications from having to manage a shared
memory space
- Virtual memory is a memory management capability of an operating system that uses hardware and software to
allow a computer to compensate for physical memory shortages by temporarily transferring data from
R.A.M to hard disk drive storage.
- V-M
- Clock speed
- 1MHz is 1 million instructions per seconds
- 1GHz is one billion instructions per second
- 1GHz is one billion instructions per second
- 1MHz is 1 million instructions per seconds
