===Supercomputer===

Supercomputers are the most powerful computers available, which have replaced mainframe computers.  These computers, which generally full large rooms like mainframes, are generally used by government agencies and large corporations.  Since these computers are so expensive, they are reserved for important and complicated computations such as  nuclear simulations and weather modeling.<ref name="Britannica">"Computer."
