Unlike pipes. FIFOs persist in the system until explicitly removed. This persistence allows them to be used for longer-tem communication channels which can survive across different executions of processes or even system reboots, provided the FIFO file is recreated.
fifo persist beyond the lifespan of the processes that use them. They remain as files in the file system until explicitly removed. This allows different processes to communicate even if they start and stop at different times.
