2. What are the advantages of having a good mix of CPU bound and I/O bound programs, while scheduling the shortterm scheduler? Discuss briefly.
Answers
Answer:
Scheduling (Computing):
In computing, scheduling is the method by which work is assigned to resources that complete the work. The work may be virtual computation elements such as threads, processes or data flows, which are in turn scheduled onto hardware resources such as processors, network links or expansion cards.
Explanation:
• We have seen that a major task of an operating system is to manage a collection of processes, and that (in some cases) a single process may be structured as a set of individual threads.
• Both of these situations raise the following issue: on a system with a single CPU (or on a multi-processor system with fewer CPU's than processes), how is CPU time divided among the different processes/threads that are competing to use it?
• The component of the operating system that addresses these issues is called the scheduler. As we shall see, scheduling is often handled on several levels, with CPU scheduling being the lowest level. So we will want to discuss scheduling in general and CPU scheduling in particular.
