Inter-process communication {{#invoke:main|main}}

When processes communicate with each other it is called "Inter-process communication" (IPC). Processes frequently need to communicate, for instance in a shell pipeline, the output of the first process need to pass to the second one, and so on to the other process. It is preferred in a well-structured way not using interrupts.

It is even possible for the two processes to be running on different machines. The operating system (OS) may differ from one process to the other, therefore some mediator(s) (called protocols) are needed.
