Abstract

Suppose you work in an office that is organized as follows:

• The databases that are used by everyone are stored on a mainframe, which has two separate disk drives for backing up daily work.

• Text and graphics are handled by a minicomputer that is connected to a laser printer and a plotter.

• Statistical work is handled by another minicomputer, which also requires a laser printer and plotter.

• Each employee uses a personal computer for preparing reports, accessing information on the mainframe, and working with either text and graphics or statistics.
