  Mainframes are large, powerful computers that are mostly used to host and manage the operation of computer systems and networks in the mainframe industry. Mainframes were invented in the 1950s and expanded on the processing power and speed of earlier computers.

  IBM is one of the major manufacturers of mainframes. They are often the backbone of large organizations, processing enormous volumes of transactions, and can be used to maintain supercomputing levels of availability and operational excellence.

• Mini/midrange computers

  Known as 'minis' or 'midranges,' mini computers are mid-sized computers that range between microcomputers and mainframe supercomputers. In the 1990s, the term refered to a certain class of computers that had a multipurpose capability but were also small enough for a single user to afford and thus could sit on the user's desk.

  Often used by small to medium-sized businesses and departments in large companies, mini computers can handle data processing tasks for many concurrent users. The term is not used much anymore, but the concept lives on in contemporary PCs.

• Microcomputer

  Microcomputers, also known as personal computers (PCs), are what most people today think of as computers. They are general-purpose micro-processing digital machines designed for individual and personal use.

  Released in the 1970s, their invention is credited to the development of small, affordable microprocessors such as the Intel 4004, which allowed engineers and hobbyists to build their own PCs. Microcomputers run on an operating system that controls peripheral hardware and allows application software to be loaded and executed.
