Crosstalk is a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit. In an telephone circuit, crosstalk can result in your hearing part of a voice conversation from another circuit. The phenomenon that causes crosstalk is called electromagnetic interference (EMI). It can occur in microcircuits within computers and audio equipment as well as within network circuits.
shared media LAN A local area network (LAN) that shares its total available bandwidth with all transmitting stations. Ethernet is the primary example, although Token Ring and FDDI networks were earlier examples. In the past, when shared media LANs ran out of capacity to serve their users effectively, they were upgraded by replacing the network hubs with switches. See hub vs. switch, LAN switch and Ethernet switch.
