hi friend,
Pipes are used to make Interprocess commmunication in the UNIX class systems.
The pipes fall in to 2 categories,
1)anonymous pipes - Used to communicate between parent/child process by fork() mechanism.
2) named pipes or FIFOs - Used to communicate between two different process (that s why named to identify where the pipe is) probably a Client/server process.

A server program can have a FIFO through which all clients can pass their messages.

There are certain limitations in pipes and FIFOs therefore , they implemented the concept of Message Queues to implement Interprocess Communication


I Dont know about how they are internally organised....
