Thereof, are Named Pipes bidirectional?

Named pipes may be used to pass data between unrelated processes, while normal (unnamed) pipes can only connect parent/child processes (unless you tryvery hard). Named pipes are strictly unidirectional, even on systems where anonymous pipes are bidirectional (full-duplex).

Additionally, what is the difference between named pipes and anonymous pipes? All instances of a named pipe share the same pipe name. On the other hand, unnamed pipes is not given a name. An unnamed pipe is only used for communication between a child and it's parent process, while a named pipe can be used for communication between two unnamed process as well.

Also, why would you want to use a named pipe?

A named pipe provides many-to-many, two-way communication between one or more processes that are not necessarily related and do not need to exist at the same time. The file name of the pipe serves as an address or contract between the processes for communication.

What are pipes in operating system?

Conceptually, a pipe is a connection between two processes, such that the standard output from one process becomes the standard input of the other process. In UNIX Operating System, Pipes are useful for communication between related processes(inter-process communication).
