A large digital computer serving 100-400 users and occupying a special air-conditioned room. At any given point in development of computer technology, the mainframe will be faster, have large main memeory, and be more capable than a minicomputer, which will in turn be faster and more capable than a personal computer. The typical personal computer in 1999 is faster than a mainframe was in 1970.

This is a type of computer that is associated with centralized rather than distributed computing.
A very large 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.
Roughly speaking, a large computer designed to support many users simultaneously.
1. 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. Note: the term usually refers to the hardware only: main storage, execution circuitry, and peripheral units. 2. (IRM) A large and powerful computer that is capable of supporting thousands of simultaneous users.
A large-capacity computer system with processing power that is significantly superior to PCs or midrange computers. Traditionally, mainframes have been associated with centralized, rather than distributed, computing environments. Skilled technicians are required to program and maintain mainframes, although client/server technology has made mainframes easier to operate from the user's and programmer's perspectives. They are generally used by large organizations to handle data processing for enterprisewide administrative tasks like payroll or accounts payable.
A large, multi-tasking computer that is used by many users.
a very large computer that is able to support thousands of users at the same time. Users access the mainframe through a terminal.
Basically, a large and powerful computer designed to be very fault tolerant. Historically, mainframes with lots of memory and disk space are hooked to a bunch of dumb terminals that can be used to access data on the mainframe, but can do nothing without the mainframe.
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. Microwave – Part of the electromagnetic spectrum between radio and light waves, microwaves can be used to transmit data from point to point. Often used to connect sites separated by a road or river, microwave links are also used to provide long distance links by telecoms network providers.
The first generation of computers. Still in use today, these very large computers are used by only the most demanding users to handle very large amounts of data. Although they are designed very differently than a PC, they share many of the same components including disk drives, memory banks and system I/O. Some design features of PCs are based on mainframe design principles, such as the backplane. Processing on a mainframe is done in “batch” mode, in which jobs are scheduled at the console. Mainframes typically do not run interactive application software such as word-processors or spreadsheets.

Mainframe is an industry term for a large computer, typically manufactured by a large company such as IBM for the commercial applications of Fortune 1000 businesses and other large-scale computing purposes. Historically, a mainframe is associated with centralized rather than distributed computing. Today, IBM refers to its larger processors as large servers and emphasizes that they can be used to serve distributed users and smaller servers in a computing network.
A computer used to control large databases, perform high volume transaction processing, and generate reports from large databases.
A large, powerful computer that works with large data chunks and supports a myriad of users simultaneously.

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.
