3.2.4.2 Multi-user systems 

A multi-user operation system is designed to allow more than one user to access and use a computer at the same time. In this case, the CPU time is shared by the users working simultaneou sly. Since the same processor caters the needs of many users (using time-slicing technique) the response time will decrease when the numbers of users increase. Such systems are also known as time-sharing systems.
