2. Supercomputers

Supercomputers are the fastest and most expensive computers in the World.

They can cost over a hundred million pounds to build and very few organisations can afford to purchase one.

They are mainly used by large universities who do a lot of research projects such as scientific research, weather modelling etc and by large organisations such as pharmaceutical companies for drug research or by the military for weapons research.

Whilst supercomputers are working, they generate so much heat that they need to be housed in specifically designed rooms with environmental controls and air conditioning systems. It is vital that the atmosphere is kept free of dust particles and special filters are used to keep the air clean.

There may be many miles of cables which connect the computer to various peripherals. In order to hide the cables, false floors and ceilings are often needed.

Supercomputers usually need their own back up electricity generator to ensure that they can continue to work even when there is a power failure.
