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.
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.
As of 2010, while mainframe technology represented less than 3% of IBM's revenues, it "continue[d] to play an outsized role in Big Blue's results". [ 27 ] IBM has continued to launch new generations of mainframes: the IBM z13 in 2015, [ 28 ] the z14 in 2017, [ 29 ] [ 30 ] the z15 in 2019, [ 31 ] and the z16 in 2022, the latter featuring among ...
As a generalization, the price targets for these smaller computers were one-tenth of the larger supercomputers. Several notable technical, economic, and political attributes characterize minisupercomputers. First, they were architecturally more diverse than prior mainframes and minicomputers in hardware and less diverse in software.
HP 3000 Series III. The HP 3000 series [1] is a family of 16-bit and 32-bit minicomputers from Hewlett-Packard. [2] It was designed to be the first minicomputer with full support for time-sharing in the hardware and the operating system, features that had mostly been limited to mainframes, or retrofitted to existing systems like Digital's PDP-11, on which Unix was implemented.
An additional 370 channel card can be added to provide mainframe-specific I/O such as 3270 local control units, 3400/3480 tape drives or 7171 protocol converters. Although a single-card product, the P/370 ran three times faster than the 7437, attaining 3.5 MIPS, on par with a low-end IBM 4381. [17]
Computer division merged with CII's minicomputer division to become Société européenne de mini-informatique et systèmes (SEMS) Tava Corporation — United States: 1983: 1984: Acquired by Replitech: Terak Corporation — United States: 1975: 1985: Acquired by Sanders Associates: TeleVideo — United States: 1975: 2011: Dissolution: Teleram ...
For example, the computers behind the first Space Shuttle simulator consisted of thirty-six 32-bit minis inputting and/or outputting data to networked mainframe computers (both IBM and UNIVAC), all in real-time. The 8/32 was used in the Lunar and Planetary Laboratory, Department of Planetary Sciences at the University of Arizona for research ...
