Redirected from Minicomputers
The term evolved in the 1960s to describe "small" server-class computers, usually taking up one or a few cabinets, compared with mainframes that would usually fill a room. They cost far less than mainframes.
As microcomputers developed in the 1970s and 80s, minicomputers filled the mid-range area between micros and mainframes. Microcomputers were single-user, relatively simple machines running simple program-launcher operating systems like CP/M or MS-DOS, while minis were much more powerful systems that ran full multi-user, multitasking operating systems like VMS and Unix. The classical mini was a 16-bit computer, while the emerging higher performance 32-bit minis were often referred to as superminis.
As of 2001, the term "minicomputer" is no longer used for the mid-range computer systems, most of which are now referred to simply as servers. This has come about as a result of several factors, including:
A number of pioneering computer companies first built minicomputers, such as DEC, Data General, Hewlett-Packard, and IBM.
Today's personal computers are descendants of the microcomputers, but architecturally their CPUs and operating systems have evolved largely by integrating features from minicomputers.
The class of minicomputers includes:
