Hop count

In telecommunication, the term hop count refers to the number of devices through which data must pass between source and destination in a telecommunications network. In some contexts, only devices operating at the network layer, such as routers and gateways, count as hops; in others, the hop count may include any signal-regenerating devices, including repeaters and bridges. A packet-switched network may base a packet's time to live on hop count. A traceroute displays the count of network layer hops in the first column.
