TAILIEUCHUNG - Lecture Operating system concepts - Lecture 27

This chapter examines two problems that plague all efforts to support concurrent processing: deadlock and starvation. We begin with a discussion of the underlying principles of deadlock and the related problem of starvation. Then we examine the three common approaches to dealing with deadlock: prevention, detection, and avoidance. | CSC 322 Operating Systems Concepts Lecture - 29: by Ahmed Mumtaz Mustehsan Special Thanks To: Tanenbaum, Modern Operating Systems 3 e, (c) 2008 Prentice-Hall, Inc.

Check whether the next state (change in system) may end up in a deadlock situation; avoid it. Plotting of Graph (Next Slide) Explains the idea!!!
