What are deadlocks? How can they be avoided?

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.
