Named pipes are a service provided to user-mode applications by the NT kernel. More specifically, the named pipe file system driver (NPFS) implements this functionality. The kernel does, however, provide executive support for NPFS. For example, the native NtCreateNamedPipeFile function is exposed via the kernel's system service dispatch table. The process that creates a pipe is the pipe server. A process that connects to a pipe is a pipe client.

Finally, there is the curiosity if a good concept could be put into good use. windows command-line redirection pipe named-pipe Named Pipes is a Windows mechanism that enables two unrelated processes to exchange data between themselves, even if the processes are located on two different networks. It's very simar to client/server architecture as notions such as a named pipe server and a named pipe client exist.
