  • communicate with other processes, regardless of where they are running

    Advanced Programming in the UNIX Environment Third Edition
     
    In the previous chapter, we looked at pipes, FIFOs, message queues, semaphores, and shared memory
    the classical methods of IPC provided by various UNIX systems.These mechanisms allow processes running
    on the same computer to communicate with one another.In this chapter, we look at the mechanisms that
    allow processes running on different computers (connected to a common network) to communicate with
    one another network IPC.
    In this chapter, we describe the socket network IPC interface, which can be used by processes to communicate
    with other processes, regardless of where they are running — on the same machine or on different machines.
    Indeed, this was one of the design goals of the socket interface. The same interfaces can be used for both
    intermachine communication and intramachine communication. Although the socket interface can be used to
    communicate using many different network protocols, we will restrict our discussion to the TCP/IP protocol suite
    in this chapter,since it is the de facto standard for communicating over the Internet.

    Processes are often seen as synonymous with programs or applications. However, what the user sees as a single application may in fact be a set of cooperating processes. To facilitate communication between processes, most operating systems support Inter Process Communication (IPC) resources, such as pipes and sockets. IPC is used not just for communication between processes on the same system, but processes on different systems.
