POWER9 is a family of superscalar, multithreading, multi-core microprocessors produced by IBM, based on the Power ISA.It was announced in August 2016. [2] The POWER9-based processors are being manufactured using a 14 nm FinFET process, [3] in 12- and 24-core versions, for scale out and scale up applications, [3] and possibly other variations, since the POWER9 architecture is open for licensing ...
The IBM System/3 was an IBM midrange computer introduced in 1969, [1] and marketed until 1985. It was produced by IBM Rochester in Minnesota as a low-end business computer [ 2 ] aimed at smaller organizations that still used IBM 1400 series computers or unit record equipment .
The IBM 2841 Storage Control Unit [3] [15] was a Direct Access Storage Device (DASD) control unit introduced with System/360, first shipped in 1965 and offered until at least 1975. The 2841 was a microprogrammed [ 16 ] control unit "intended for use in controlling access to a disk or strip file or a slow-speed drum storage unit."
IBM POWER is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by IBM. The name is an acronym for Performance Optimization With Enhanced RISC. [1] The ISA is used as base for high end microprocessors from IBM during the 1990s and were used in many of IBM's servers, minicomputers, workstations, and ...
IBM enhanced one of GM-NAA I/O's successors, the SHARE Operating System, and provided it to customers under the name IBSYS. [1] [2] As software became more complex and important, the cost of supporting it on so many different designs became burdensome, and this was one of the factors which led IBM to develop System/360 and its operating systems ...
Initially, model 1 (4952, Model C), [4] model 3 (IBM 4953) and model 5 (IBM 4955, Model F [4]) processors were provided. Later processors were the model 4 (IBM 4954) and model 6 (IBM 4956). Don Estridge had been the lead manager on the IBM Series/1 minicomputer. He reportedly had fallen out of grace when that project was ill-received.
Lotus 1-2-3 is a discontinued spreadsheet program from Lotus Software (later part of IBM).It was the first killer application of the IBM PC, was hugely popular in the 1980s, and significantly contributed to the success of IBM PC-compatibles in the business market.
On September 11, 2012, IBM extended the end of service for V6.1 by a full year, to September 30, 2013, and announced new version-to-version migration incentives and assistance. [27] It is a Java EE 1.4 compliant application server and includes the following function:
