2. Starter
List as many computer systems as you can.

3. Part 1 – Computer Systems The general purpose machine?
A computer is any machine or device that can be programmed with a set of instructions. Most computers with a CPU, such as smartphones and PCs, can be described as general purpose machines because they can be used for many different things. Software enables a computer to be a games machine, web browser, word processor and perform a wide range of functions.
