Imagine that pipe and fifo are initialized between two pairs of processes, respectively. What difference can there be in their work if they interact in the same way?

    The main difference that comes to me immediately is that pipes can be made only between related processes. Further, if the pipe is closed, then it is lost, and you can always re-open the fifo, and with new parameters.

      @mikillskegg, and what are related processes? Multiple processes run by a single shell command - they are related. Then yes, named pipes are addressed by name and family ties are optional. - alexlz

      Here I meant the processes "parent-child" or "fraternal". - skegg
