Operating Software
... In multi-user systems, the computer checks each terminal in turn by “polling” or “round robin” to see whether the user needs it. This happens so quickly, and CPU speeds are so fast, that the user thinks he has continuous use of the system. The response-time may be slowed, however, if the system is b ...
