Beginner Topic 16 of 51 Operating Systems

Inter-Process Communication

Mechanisms for processes to exchange data.

How it works

IPC mechanisms include pipes, named FIFOs, message queues, shared memory, sockets and signals. Shared memory is fastest but needs synchronization.

Where it is used

Microservices on one host, shell pipelines.

Common pitfall

Choose by need: simple streams use pipes, bulk data uses shared memory.

Where it fits in the course

Inter-Process Communication is topic 16 of 51 in Operating Systems, rated Beginner. It follows Fork and Exec. The next topic is Pipes and Signals.
