'''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. | '''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).

Notice that the identification and distinction between PC-based clusters/servers, minicomputers, mainframes, and supercomputers aren't based on size, performance, or price, but system architecture, extensibility, and reliability; As integrated circuit technology evolves, a mainframe could be the size of a minicomputer (e.g. IBM System 390 Integrated Server 3006), a minicomputer could be a size of a relatively big personal computer/PC based server (e.g. IBM i5 515), while a regular laptop PC could achieve the performance of multi-million dollar mainframe in 1980s just by emulating it. | Notice that the identification and distinction between PC-based clusters/servers, minicomputers, mainframes, and supercomputers aren't based on size, performance, or price, but system architecture, extensibility, and reliability; As integrated circuit technology evolves, a mainframe could be the size of a minicomputer (e.g. IBM System 390 Integrated Server 3006), a minicomputer could be a size of a relatively big personal computer/PC based server (e.g. IBM i5 515), while a regular laptop PC could achieve the performance of multi-million dollar mainframe in 1980s just by emulating it. | ||
