The most common way to connect to an ethernet cable these days is through a CAT5 or CAT6 cable that uses an RJ45 connector. RJ stands for ‘Registered Jack’ and 45 is the designation number of this type of connection:

The simplest kind of ethernet connection you can have with modern equipment is a 100mbit connection. For 100mbit, you only need 4 wires in the cable. The green pain and the orange pair:
