Section-B

Case study

In single user dedicated systems, it is generally obvious when a program goes into an infinite loop. But in the multi-user systems running tens of hundreds of processes, it cannot easily be determined that an individual process is not progressing.

Case problems:

problem5)a) Can the operating systems determine that the process is in an infinite loop?

b) What reasonable safeguards might be built into an operating system to prevent process in infinite loops from running indefinitely?
