Term used to describe a large and power computer and its associated storage devices. Users may be provided with small terminal units resembling personal computers; these have software that enables the user to access the data on the mainframe. The terminal units are linked to each other and to the mainframe by a computer network. Today's personal computers and laptops are much more powerful than early mainframe machines, so many tasks once carried out by mainframes are now done on PC's or mobile devices.
