hop

hop  1. n. 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 {UUCPNET} 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. To log in
   to a remote machine, esp. via rlogin or telnet. "I'll hop over to
   foovax to FTP that."
