What is actually inter-process communication and how can one handle and create this in Linux environment. I want to know about this term in detail as I do not have a least idea about this term

The Linux IPC also called as Inter-process communication facilities provide a method for multiple processes to communicate with one another. Some of the various IPC used in Linux environment are:
Half-duplex UNIX pipes
FIFOs (named pipes)
SYSV style message queues
SYSV style semaphore sets
SYSV style shared memory segments
Networking sockets
Full-duplex pipes (STREAMS pipes)

UNIX pipes mentioned above form a IPC tool or method because it is a method of connecting the standard output of one process to the standard input of another. They are termed as Half-duplex UNIX pipes because they provide a method of one-way communications between processes.

The FIFO or named pipe is similar to that of pipe with some differences namely named pipes exist as a device special file in the file system and when all I/O is done by sharing processes, the named pipe remains in the file system for later use.
