Final answer:
The two wiring schemes defined by the TIA/EIA organization for Ethernet installation are T568A and T568B. They specify the arrangement of wires in an RJ-45 connector and are used with UTP and STP Ethernet cables.
Step-by-step explanation:
The two wiring schemes defined by the TIA/EIA organization for Ethernet installation in homes and businesses are T568A and T568B. These schemes specify the arrangement of wires inside an RJ-45 connector.
T568A and T568B use different wire color arrangements, but both provide the same functionality. They define which pin on the RJ-45 connector connects to which wire in the Ethernet cable. For example, T568A assigns white-green to pin 1, green to pin 2, white-orange to pin 3, blue to pin 4, white-blue to pin 5, orange to pin 6, white-brown to pin 7, and brown to pin 8.
UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) are types of Ethernet cables that can be used with these wiring schemes. UTP is the most common type used in homes and businesses, while STP provides additional shielding against electromagnetic interference.
