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.
