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.
IBM mainframe. IBM mainframes are large computer systems produced by IBM since 1952. During the 1960s and 1970s, IBM dominated the computer market with the 7000 series and the later System/360, followed by the System/370. Current mainframe computers in IBM's line of business computers are developments of the basic design of the System/360.
The history of IBM mainframe operating systems is significant within the history of mainframe operating systems, because of IBM 's long-standing position as the world's largest hardware supplier of mainframe computers. IBM mainframes run operating systems supplied by IBM and by third parties. The operating systems on early IBM mainframes have ...
ESA/390. z/Architecture. v. t. e. The IBM System/360 ( S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. [ 1] It was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large.
An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [ 2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions. [ NB 1] Like OS/390, z/OS combines a number of formerly separate, related ...
IBM System p. The IBM AS/400 ( Application System/400) is a family of midrange computers from IBM announced in June 1988 and released in August 1988. It was the successor to the System/36 and System/38 platforms, and ran the OS/400 operating system. Lower-cost but more powerful than its predecessors, the AS/400 was extremely successful at ...
Multiple Virtual Storage, more commonly called MVS, is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF .
IBM 2741, a widely emulated computer terminal in the 1960s and 1970s. (keyboard/printer) A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing [ 1] data from, a computer or a computing system. [ 2] Most early computers only had a front panel to input or display bits ...
