Supercomputers are fastest of all computers, needed where vast numbers of calculations are carried out e.g weather forecasting. Supercomputers run few programs very fast rather than lots of programs at the same time.

Computer Systems- system is a collection of parts that work together for a particular purpose. i.e transport and banking system. A computer system is a collection of items working together and controlled by a computer i.e mobile phones, microwaves and car engines.
