OS2: Process Synchronization-Unit 1: Race Condition

A race condition or race hazard is a flaw in a system or process whereby the output of the process is unexpectedly and critically dependent on the sequence or timing of other events. The term originates with the idea of two signals racing each other to influence the output first. Race conditions arise in software when separate processes or threads of execution depend on some shared state. 2.0 Objectives At the end of this unit you should be able to: • Define Race condition • Describe some real life examples of race condition • Describe computer security in view of race condition
