The Inter-Process Communication Questions & Answers below include solutions and links to the relevant topic. This is helpful for users who are preparing for their exams and interviews, or professionals who would like to brush up on the fundamentals of the Gunn Diode. Inter-process communication is about the processes establishing communication with each other. It is specifically a mechanism provided by OS among processes and allows them to manage shared data. There are two various processes in the system. One is Independent and the other is cooperating. The processes that don't share their data and remain unaffected by the other processes executing in the system are known as Independent Processes. The processes occurring in the system that allows the data to be shared are referred to as Cooperating processes and are affected by the other processes occurring in the system. Hence Inter-process communication belongs to cooperating processes. There are multiple reasons to allow process cooperation. They are Information sharing i.e., various users can access the same information simultaneously. Computational speedup i.e., a task is split into sub-tasks and is run concurrently and speeds up the system, Modularity is gained and is convenient. Name Email 1).
