What is required when more than one person uses a central computer at the same time?

A. Light pen
B. Mouse
C. Digitizer
D. Terminal

Check Answer

The correct answer is D) Terminal.

When multiple users need to access a central computer at the same time, they typically use terminals. A terminal is a device that allows users to interact with the central computer by sending commands and receiving data. Terminals can take many forms, including text-based terminals that display only text and graphical terminals that display images and other visual elements. Terminals can be connected to the central computer through a network, serial or parallel port, or wireless connection. The other options listed – light pen, mouse, and digitizer – are input devices used by individual users to interact with a computer, but they do not enable multiple users to access a central computer simultaneously.
