Explain process scheduling in multiprogramming

Multiprogramming is able to be defined as a set of following features:

1.      A mix of CPU bound and IO bound processes live in the system

2.      An IO bound process has superior priority that a CPU bound process

3.      Process priorities are static and do not change with time

4.      Process scheduling is preventative a low priority running process is preempted if a higher priority process becomes ready

The following figure exemplify the process state transitions in multiprogramming
