1.2. Available Means of Transmission
Ethernet [2] can be a good choice for home networking if home-run Category 5 or structured wiring is available. Ethernet can also be installed within a room with twisted pair patch cables. Bob Metcalfe and his Xerox PARC (Palo Alto Research Center) colleagues developed Ethernet in late 1972 to interconnect personal workstations. The IEEE standards for the first version of twisted pair–based Ethernet, 10BaseT, was released during 1990. 10BaseT has a transmission data rate of 10 megabits per second (Mbps) over two pairs of Category 3 or Category 5 twisted pair cable. The first 100-Mbps version of twisted pair–based Ethernet, 100BaseTX, was standardized during 1995. Network Interface Card (NIC), adaptors, and ...
