The operating system chooses a job from the job pool and begins executing a job, when such job requires waiting for any I/O operations the CPU is switched to other job.

Default label: The destination for all values employed in a switch statement expression which do not contain explicit case labels. The default label is not obligatory.
State Space Reduction: JPF is a so-called explicit-state model checker, as it enumerates all visited states, and therefore suffers from the state explosion problem inherent in analyzing large programs. It also contains garbage collection, because a ty
