characteristics
දත්ත The entered data is processed and output without any delay.
There are times when the user does not have an interface and there are smaller interfaces.
Responds in less time.
Cost is high.
Has more memory capacity and efficiency.
6. Time sharing systems
A lot of users or applications work by allocating processor time. An example of this is when a number of people connect to the main computer through a network system.
characteristics
Immediate response time
Processor lazy time is short.
