Special purpose computers
These are computers developed in a way that allows them perform a specific task. NB: these computers cannot perform any other task except the one they were meant to do.
Examples of these computers include;

- Remote – control a specified electronic device’ functionality.
- Mobile phones- used in communication only.
- Calculators- carry out calculations only.Microwave ovens e.t.c
#advantage of using special purpose computers is that, they are very efficient and very fast.
These are mainly General purpose computers that have been dedicated to perform a particular task. E.g. a desktop computer dedicated to document processing or accounting.
