Well, they can be on ACTUAL disk space - or on a RAMdisk or just a reserved stretch of RAM. The last one is quickest - but most taxing on run-time resources. > Quoting from this page: > > https://www.geeksforgeeks.org/piping-in-unix-or-linux/# > > In Linux, a pipe is not a regular file but a type of inter-process > communication (IPC) mechanism that acts as a buffer, which can be > used to connect the output of one process to the input of another. > Although pipes are not files, they are implemented using file > descriptors and share many behaviors with files.

IF you are doing multi-threaded/process style pgms then you almost HAVE to use them if you want to xmit more than a few bytes between parents/children. A few years back I was experimenting with TCP/UDP servers and found that it could be very useful to transmit a few dozen bytes worth of active data between parents/children. SO ... learn yer pipes !
