==Terminology==

'''Desk-size Computers''', as a slang of '''MiniComputers''' due to their size and usual appearance, are a type of smaller general-purpose computer with size, price, and extensibility less than a mainframe computer, but still higher than microcomputers, later commonly known as personal computers (PCs). Usage and demands of minicomputers have greatly shrunk and are being taken over by PC-based server clusters over the years, but some of them are still serving irreplaceable roles for their high reliability and extensibility.

'''Supercomputers''' are computers specifically built for high-performance mathematical/scientific calculation with a high level of performance as compared to a general-purpose computer.
