Hopefully this clears up the confusion, and you get the basic geometric rule. Concentricity error is exactly one half of the runout error. Still donât believe it, then try it for yourself in your favorite CAD program or with a physical 2D model.
Ethernet (the name commonly used for IEEE 802.3 CSMA/CD) is the dominant cabling and low level data delivery technology used in local area networks (LANs). Ethernet transmits data at up to ten million bits (i.e., 10 megabits) per second (10 Mbps).
Gigabit Ethernet is another term of Ethernet in computing network, for carrying on the traffic at the rate of 1000 Mbit per second. It was introduced in 1999, just after three years of Fast Ethernet.
