As a process executes it changes state according to its
circumstances. Unix processes have the following states:
1.Running : The process is either running or it is ready to
run .
2.Waiting : The process is waiting for an event or for a
resource.
3.Stopped : The process has been stopped, usually by
receiving a signal.
4.Zombie : The process is dead but have not been removed
from the process table.
