In computing, a named pipe (also known as a FIFO for its behavior) is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC). The concept is also found in OS/2 and Microsoft Windows, although the semantics differ substantially.

A traditional pipe is “unnamed” and lasts only as long as the process. A named pipe, however, can last as long as the system is up, beyond the life of the process. It can be deleted if no longer used. Usually a named pipe appears as a file and generally processes attach to it for inter-process communication.

Are Windows named pipes?
Microsoft Windows Pipes utilizes a client-server implementation whereby the process that creates a named pipe is known as the server and the process that communicates with the named pipe is known as the client. By utilizing a client-server relationship, named pipe servers can support two methods of communication.
