RJ45 Connector
A lot of Ethernet local area networks use 10BaseT
twisted pair wiring. 10BaseT networks are
physically laid out in a star topology, where each
piece of equipment on the network is connected to
a central hub. The wiring is connected to devices
using a plug that resembles a phone jack, called
RJ45.
