UTP cables.

The Telecommunications Industry Association (TIA) and the Electronic Industries Alliance (EIA) worked together to provide the TIA/EIA cable specifications for LANs. Two of the most common TIA/EIA cable specifications include the 568-A and 568-B standards. Both of these standards typically use the same Cat 5 or Cat 6 cable, but with a different termination color code.

There are three different types of twisted pair cables that are used in networks:

Straight-through – Connects dissimilar devices, such as a switch and a computer, or a switch and a router.

Serial cable

Another cable type that is common in networks is a serial cable. A serial cable is typically used to connect the router to an Internet connection. This Internet connection may be to the phone company, the cable company, or a private ISP.
