Context Switching
The Saving the context of one process and loading the context of another process is called CONTEXT SWITCHING.
Each and every time when process is moving from one state to another , the context of the process will change.
Minimum process required for context switching.(Exception:-Round Robin)
The context switching will also take some time , so if the context of the process is more than context switching time will also increase which is undesirable.
context switching time is considered as overhead for the system.It is perform a dispatcher.
Dispatcher:-It is responsible for saving the context of 1 process and loading the context of another process. The context switching is done by dispatcher.
