Application interoperability is one of the fundamental requirements for group-work as well as network computing. Applications have a need to interoperate in numerous ways and one of the imperatives for interoperability is the availability of flexible and efficient communication mechanisms. Communication Mechanisms, here, are software abstractions that enable processes to exchange information between one another, in other words, abstractions that enable interprocess communication (IPC). The purpose of this report is to bring out the various features of commonly available IPC mechanisms and the effectiveness of these mechanisms in building distributed systems.
