Uplink
1. A port found on network hubs, switches, and routers that enables them and all computers or devices connected to them to connect to a larger network. For example, a home network may have a router or switch that connects to a broadband connection through the uplink port, enabling it to share that broadband connection with all computers that are connected to it.
2. An uplink is also a one-way connection from a users device such as a cell phone to a network or server.
