The system calls for process management are
Fork() > create child process
Vfork() > create child process (copy-on-write only)
exec() > exec to do a different task
wait() > wait for a process to complete execution
kill() > to send a signal to a process
signal() > to handle a signal
sigaction() > handle signal
exit() > exit from a process execution
_exit() > same as exit() but with out clean up
