This class assignment was for us to build a Ethernet cable. The Ethernet cable is used to connect the PC to another PC or to a router. To understand how to build the cable, we need to understand the color map used to build the cable. Two RJ45 modular plug and a raw ethernet cable is needed. The Ethernet cable can be built in 2 different ways which one is called the straight-through cable and the other is called crossover cable.
