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).
Ethernet crossover cable is used to connect a computer network made up of two or more computers. This type of network cable eliminates the need for network switches or routers. The cable also allows the computers to be connected using their network adaptors, such as the network interface card (NIC). Fiber optic network cables are used for networks that span large distances. As a result, this type of cabling has several layers of protective coating.
