Deadlock vs. Impasse — What's the Difference?

In concurrent computing, a deadlock is a state in which each member of a group waits for another member, including itself, to take action, such as sending a message or more commonly releasing a lock. Deadlocks are a common problem in multiprocessing systems, parallel computing, and distributed systems, where software and hardware locks are used to arbitrate shared resources and implement process synchronization.In an operating system, a deadlock occurs when a process or thread enters a waiting state because a requested system resource is held by another waiting process, which in turn is waiting for another resource held by another waiting process.

A bargaining impasse occurs when the two sides negotiating an agreement are unable to reach an agreement and become deadlocked. An impasse is almost invariably mutually harmful, either as a result of direct action which may be taken such as a strike in employment negotiation or sanctions/military action in international relations, or simply due to the resulting delay in negotiating a mutually beneficial agreement.
