What are deadlocks? How can they be avoided?
Ans: Deadlock considers to a particular condition when two or more processes are every waiting for another to release a resource, or much more than two processes are waiting for resources in a circular chain. Deadlock is a general problem in multiprocessing in which many processes share a particular type of mutually exclusive resource termed as a software, or soft, lock. Computers that are intended for the time-sharing and/or real-time markets are often equipped along with a hardware lock (or hard lock) that assures exclusive access to processes, forcing serialization. Deadlocks are specifically troubling as there is no general solution to avoid (soft) deadlocks.
