Answer Posted / sreekanth gurram
basically schedulers are of 3 types.1)long term scheduler
2)short term scheduler
3)medium term scheduler
long term scheduler selects the processes which are in the
disk(input queue)and load them in to the main memory.
The short term scheduler selects the processes in the main
memory which are waiting for cpu and allocate them to the
cpu for execution.The medium term scheduler selects the jobs
which are waiting for the I/O devices and remove them from
the contest for the cpu and place them in the appropriate
device queue
DISPATCHER:
Another component involved in the CPU scheduling function is
the dispatcher.
The dispatcher is the module that gives control of the CPU
to the process selected by the short-term scheduler. This
function involves:
Switching context
Switching to user mode
Jumping to the proper location in the user program to
restart that program
The dispatcher should be as fast as possible, given that it
is invoked during
every process switch. The time it takes for the dispatcher
to stop one process
and start another running is known as the dispatch latency.
