Inter-Process Communication (IPC) refers to the exchange of data among multiple threads in one or more processes, either locally or on remote computers connected in a network. The available methods of IPC vary based on the bandwidth and latency of communication between the threads, and the type of data being transmitted. IPC includes subtopics such as message passing, synchronization, shared memory, and remote procedure calls (RPC).
