There are several mechanisms for inter-process communication (IPC) in UNIX systems, including message queues, shared memory, and semaphores. Message queues allow processes to exchange data by placing messages into a queue that can be accessed by other processes. Shared memory allows processes to communicate by declaring a section of memory that can be accessed simultaneously. Semaphores are used to synchronize processes so they do not access critical sections at the same time.

4. UNICAST AND MULTICAST IPC When communication is from one process to a single other process , the IPC is said to be a unicast. e.g. Socket communication. .When communication is from one process to a group of processes , the IPC is said to be a multicast. e.g. Publish/Subscribe Message model.
