Interprocess communication allows one process to send or receive a message to or from another process. Normally, in Unix, processes are in a separate address space and cannot exchange information. With interprocess communication, they are allowed to exchange information to each other.
They have different models of interprocess communication. In Windows, processes generally communicate to each other by sending "messages". These messages can carry some data. In Linux processes can communicate in a number of ways: * Sending Signals to each other (used for simple signalling, the signals do not carry data). * Using files and network sockets, which allows two-way communication between processes, but involves more programming overhead. * Other IPC (interprocess communication) methods such as System-V message queues, semaphores, and shared memory.
An anonymous pipe, in computing, is a first-in first-out communication channel which may be used for one-way interprocess communicaion.

You don't indicate what you mean by "communication". Since there are many different answers your question needs to be more specific.

Processes might need to communicate to each. Interprocess of synchronization is the?æ management of resource among process. It ensures only a single thread (process) access a resource at a particular time.
When the two or more process run simultaneously at same time, the systems allocate the resources to both the process, so that both the process can run unitteruptly, this phenomenon is called Interprocess Communication.
No. If cooporating processes are to actually cooporate with each other, there must be some kind of inter-processing communication between them so they know when to wait for the other process to complete some task that is needed by the first process.
vxworks is used to control network and communication devices. vxworks is similar to unix but it uses less processing power than unix.
SystemV IPC covers: messages (msgctl, msgget, msgrcv, msgsnd), semaphores (semctl, semget, semop) and shared memories (shmat, shmctl, shmdt, shmget)
Typically, all functions in any program constitute a single process. Multiple processes can communicate via Interprocess Communication (IPC), but are usually regarded as separate programs.
