What does the ethernet 10base T connector look like. It says RJ45?
An RJ45 jack is very similar to a regular telephone jack, which is an RJ-11 jack, only larger. Both of them use four wires, but the signals carried on the wires are used differently. An RJ45 connector is used for local area network Ethernet connections, which carry data at 10Mbps. 10BaseT is the term for 10Mbps Ethernet using a twisted pair cable.
