Time Sharing System

A time sharing system has many (even number of) user terminals connected to the same computer simultaneously. Using this terminals, multiple users can work on the system simultaneously. 

 Advantage:

a)      Reduces CPU idle time.

b)      Provides advantages of quick response time.

c)      Offers good computing facility to small computer.
