1. The X25-Demodulator machine does not provide a mechanism for interrupts; any process in the X25 OS is non-preemptive. In addition, the OS does not provide a means for selecting the next job to run. Provide the design and justification for your mechanism that supports process dispatching.
2. A spawned process (child) may proceed independent of the parent, as one method of OS process hierarchy management; another design is to have spawned processes directly linked to its parent, thus a child may only exist if the parent exists. Discuss the design advantage and disadvantage of each approach throughout the process lifecycle.
