interprocess communication

  • Shared memory permits processes to communicate by simply reading and writing to a specified memory location.
  • Mapped memory is similar to shared memory, except that it is associated with a file in the filesystem.
  • Pipes permit sequential communication from one process to a related process.
  • FIFOs are similar to pipes, except that unrelated processes can communicate because the pipe is given a name in the filesystem.
  • Sockets support communication between unrelated processes even on different computers.[-advanced linux programming]
