ABSTRACT
Networks based on copper cabling generally use one of two main cable types: coaxial or twisted-pair.ARCnet started with RG-62/U and RG-59/U coaxial cable, but now includes twistedpair and even fiber-optic cabling. Likewise, Ethernet, which was defined in the IEEE 802.3 standard, was originally implemented only on thick coaxial baseband cabling. But the Ethernet standard has expanded to include broadband coaxial, fiber-optic cabling, and twisted-pair.
