Deadlock Management Strategies – Deadlock Prevention

Deadlocks occur if and only if all the four Coffman conditions are met. Preventing a deadlock is possible if any one or more of these conditions are not satisfied. Deadlock prevention is thus a very important part of the deadlock management strategies.

Elimination of the Mutual Exclusion Condition: – The condition of the mutual exclusion […]

Deadlock Management Strategies – Deadlock Detection

The resources of a system are limited and therefore when the two processes compete for them, a deadlock is likely to occur. Now, since the processes have the right to access the resource and even hold it, the other processes are prevented from utilizing these resources and thus they are put in to a waiting […]
