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

When many people share one central computer at once, each needs a terminal to reach it.

A light pen is a pointing input device, not a shared access station.

A digitizer captures drawings, not multi user access.

A mouse is a single pointing device, not what allows sharing.

A terminal offers a screen and keyboard linked to the central machine.

Add-on: terminals without their own processing power are called dumb terminals.
