Definition of mainframe in English English dictionary: A large, powerful computer able to manage very many simultaneous tasks and communicate with very many connected terminals; used by large, complex organizations (such as banks and supermarkets) where continuously sustained operation is vital; A "mainframe" originally meant the cabinet containing the central processor unit of a very large computer After minicomputers became available, the word mainframe came to refer to the large computer itself The older computers used many large vacuum tubes and generated a lot of heat, thus requiring specially air-conditioned rooms A single computer might have hundreds of users at a time Today, because the large vacuum tubes have given way to transistors, a desktop personal computer can have as much power as a mainframe computer that once filled a whole room Mainframes in use now often have smaller computers as front end processors; This is a type of computer that is associated with centralized rather than distributed computing; A mainframe or mainframe computer is a large powerful computer which can be used by many people at the same time and which can do very large or complicated tasks. a large powerful computer that can work very fast and that a lot of people can use at the same time. Digital computer designed for high-speed data processing with heavy use of input/output units such as large-capacity disks and printers. They have been used for such applications as payroll computations, accounting, business transactions, information retrieval, airline seat reservations, and scientific and engineering computations. Mainframe systems, with remote "dumb" terminals, have been displaced in many applications by client-server architecture; A large, expensive, enterprise computer that can support many simultaneous users and processes; a large digital computer serving 100-400 users and occupying a special air-conditioned room; A mainframe is any computer larger than a small piece of furniture A modern mainframe is more powerful than a modern workstation, but more expensive and more difficult to maintain; (computer science) the part of a computer (a microprocessor chip) that does most of the data processing; the CPU and the memory form the central part of a computer to which the peripherals are attached; A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously In the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers; Typically, a large-scale computer normally supplied complete with peripherals and software by a single, large vendor, often with a closed architecture (Not recommended ) See OSI; Mainframes are ultra-high-performance computers made for high-volume, processor-intensive computing They are typically used by large businesses and for scientific purposes In the hierarchy of computers, mainframes are right below supercomputers, the most powerful computers in the world However, a mainframe can usually execute many programs simultaneously at a high speed, whereas supercomputers are designed for single processes; A large, multiuser machine, generally accessed by terminals and supporting a large number of users A single large mainframe (KSUVM) hosts all of KSU's academic administration functions Before the advent of microcomputers, almost all computing was done on mainframes, many of which cost several million dollars; A very large computer capable of supporting hundreds of users running a variety of different programs simultaneously Often the distinction between small mainframes and minicomputers is vague and may depend on how the machine is marketed Example of a mainframe: the OIT-administered IBM computer that supports TSO and WYLBUR; A large computer, usually at a central location, which serves many users and is capable of turning out much work; Mainframe is an industry term for a large high-level computer that is dedicated to intensive computational operations "Dumb" terminals are usually connected to a mainframe; A high level computer designed for the most intensive computer tasks; Traditionally, a computer with a very large memory and storage capacity, capable of serving many users simultaneously As personal computers and networks have become more common and powerful, they are serving many of the needs once met by mainframes; A computer, usually in a computer center, with extensive capabilities and resources to which other computers may be connected so that they can share facilities; n 1 A large computer featuring downloadable microcode, rich I/O paths, substantial integrity enforcement, degradated mode capability, multiple virtual machines, and terabyte address spaces 2 The central patch panel for a facility's cabling system 3 slang Any computer bigger then a PC or Macintosh See also MiniComputer; A very high-powered computer - used to process large volumes of data or transactions, mainframes support multiple users at dumb terminals, though they can connect to PCs via "middleware" or by using a terminal emulator; A high-level computer often shared by multiple users connected by individual terminals; A mainframe is a large host computer; {i} main computer which can serve many users simultaneously (Computers); A large computer supporting many users; Mostly a mainframe is only a mainframe when compared to a desktop computer It's bigger and much more powerful Sometimes it's called a server or CPU; This word represents an entire computing paradigm Typically, mainframe computers are very large, are housed in a central, secure location, and offer memory and disk-storage capacities that desktop microcomputers heretofore could not match Historically, SIUC mainframes have been set up to handle (1) noninteractive (sometimes called "batch") computing jobs through the Multiple Virtual Storage (MVS) operating system and (2) multiuser, interactive computing through networked workstations and dumb terminals Microcomputers have shrunk in size, dropped in price, and grown in memory and disk capacity, and they now approach the lower-end mainframes in computing power The time-sharing paradigm used by the mainframe has been replaced with the client/server paradigm; The central processing unit of a large computer, usually receiving input from a number of terminals; A powerful computer capable of organizing and executing multiple processing tasks at high speeds A mainframe often acts as the controlling agent in a centralized computing system; A large computer, usually one to which other computers and/or terminals are connected to share its resources and computing power; A large, centralized computer system; users are networked to the mainframe, and their individual workstations consist of terminals without independent processing units or storage
