You have been hired as a consultant to help a start-up organization migrate from its stand-alone computers currently using Windows XP to a more modern multiprogramming, multiuser environment. The company is planning on centralizing databases, file servers, and corporate information in a data center, and it needs help determining what operating system to use for its servers.

Management was pleased with your report and has approved your recommendation. However, they do not understand how a computer system can execute many programs at the same time or what happens when a program is preempted during execution.

They ask you to explain how the operating systems you selected handle deadlock avoidance.

Your task is to provide at least 2 different mechanisms used in interprocess communication and at least 2 mechanisms to handle deadlock in a distributed environment.
