A minicomputer, or colloquially mini, is a type of smaller general-purpose computer developed in the mid-1960s [1] [2] and sold at a much lower price than mainframe [3] and mid-size computers from IBM and its direct competitors.
One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has value, as it provides a ranked categorization of devices. It also ranks some more obscure computer sizes.
An IBM System z9 mainframe. A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
Midrange computers, or midrange systems, were a class of computer systems that fell in between mainframe computers and microcomputers. [1] [failed verification]This class of machine emerged in the 1960s, with models from Digital Equipment Corporation (PDP lines), Data General (), and Hewlett-Packard (HP 2100 and HP 3000) widely used in science and research as well as for business - and ...
From Minicomputer: A minicomputer (colloquially, mini) is a class of multi-user computers that lies in the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems (microcomputers or personal computers). The class at one time formed a distinct group with its own ...
The best-known [citation needed] early system was the Altair 8800, introduced in 1975. The term "microcomputer" has practically become an anachronism as it has fallen into disuse. [1] These computers include: Desktop computers – A case put under or on a desk. The display may be optional, depending on use.
These PCs later formed the basis for the system console on VS7000 and later series of the Wang mid-frame series, being used for the initialisation of the boot process. One of the distinguishing features of the Wang PC was the system software. Similar to the Wang VS minicomputer, the command line was not evident.
