First, no Named pipes1, what is the pipelineA pipeline is one-way, first-out, connecting the output of one process to the input of another process. One process (write process) writes data at the end of the pipeline, and another process (read process) reads the data at the head of the pipe.2. Pipeline CreationNameless pipe: (only) communication between the parent and child processes.Famous pipeline: Communication
