Final answer:
TIA/EIA-568-A and TIA/EIA-568-B are the standardized pin/pair assignment methods for twisted pair cabling used for commercial and residential cabling systems respectively.
Step-by-step explanation:
The standardized pin/pair assignment methods for twisted pair cabling are known as TIA/EIA-568-A and TIA/EIA-568-B standards. Developed by the Telecommunications Industry Association/Electronic Industries Alliance, these standards are used to determine design parameters for structured cabling systems for buildings and between buildings in campus environments. The TIA/EIA-568-A standard is used for commercial building telecommunications cabling and the TIA/EIA-568-B standard is used for residential cabling systems. Both of these standards help to ensure that cables are properly twisted and pinned for maximum data transmission efficiency.
