       1. n. [common] One file transmission in a series required to get a file
       from point A to point B on a store-and-forward network. On such networks
       (including the old UUCP network and and FidoNet), an important
       inter-machine metric is the number of hops in the shortest path between
       them, which can be more significant than their geographical separation. See
       bang path.
       2. v. [rare] To log in to a remote machine, esp. via rlogin or telnet. “
