What is a pipe operating system?

Pipe is used to combine two or more commands, andin this, the output of one command acts as input to anothercommand, and this command's output may act as input to the nextcommand and so on. It can also be visualized as a temporaryconnection between two or more commands/ programs/processes.

What is the difference between named pipes and anonymous pipes?

All instances of a named pipe share the samepipe name. On the other hand, unnamed pipes is notgiven a name. An unnamed pipe is only used for communicationbetween a child and it's parent process, while a namedpipe can be used for communication between twounnamed process as well.
