To understand the difference between Ethernet II and 802.3, you first must know how Ethernet works. While Ethernet cables transmit data, their role is relatively simple compared to that of the Ethernet card — also referred to as an adapter. It’s within the function of this card that you find the differences between Ethernet II and 802.3.

“Twisted Pair” is another way to identify a network cabling solution that’s also called Unshielded Twisted Pair (UTP) and was invented by Alexander Graham Bell in 1881. Indoor business telephone applications use them in 25-pair bundles. In homes, they were down to four wires, but in networking we use them in 8-wire cables. By twisting the pairs at different rates (twists per foot), cable manufacturers can reduce the electromagnetic pulses coming from the cable while improving the cable’s ability to reject common electronic noise from the environment.
