Multiplexing: Multiple users simultaneously use the same CPU on their terminals.
Independence: Users can operate independently of each other, mutual interference, and not confuse each other.
Timeliness: Users in a short period of time can be a timely response to the system.
Factors that affect response time: The number of terminals, the size of the time slice, the amount of information exchanged, the speed of information exchange.
