Write a short note on FIFO

Question

Write a short note on a FIFO?

Answer 1

FIFO is otherwise termed as 'named pipes'. FIFO (or first-in-first-out) is a special file that is said to be data transient. One time data is read from named pipe, it can’t be read again. As well, data can be read only in the order written. It is employed in interprocess communication where a process writes to one end of the pipe (or producer) and the other reads from the other end (or consumer).
