Q. Explain about System Deadlock?

A deadlock denotes to the condition when simultaneous processes are holding resources and putting off each other from finishing their execution.  

 The consequent situations can avoid deadlock from happening:

 1)   Mutual exclusion: All processes are given exclusive control of resources allotted to it.

 2)  Non-preemption:  A process isn't permitted to free its resources until task is completed.

3)  Wait for: A process may hold resources at the same time as waiting for extra resources.

4) Circular wait:  Many processes wait for resources from other processes in a circularly dependent circumstance.
