If you look at Ethernet cables, you will see Cat 5, Cat 5e type. It is installed on the computer LAN port. It is called RJ 45 connector.
Now, this connector is used to connect one computer to another. So you need to know how to connect the colors of the wires in this cable. This cable is called an unsuited twisted pair (UTP) cable. It has 8 wire cables.
This Ethernet cable is referred to as the T568-A and T568-B, so the T568-A is the T568-A cable storage method. Where the T-568A is used on both sides of the LAN head (as shown below), it is used to connect a computer to an intermediate switch or hub (also known as a straight-line method). Where the T-568B is used on both sides of Lan’s head (as shown in the figure below), it is used to connect a computer to an intermediate switch or hub (also called a direct connection method).
