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).
Techopedia explains Ethernet Adapter. The most common kind of Ethernet adapter is a PC card, which has an Ethernet connection and a circuit board. Some versions of these adapters can be simply fitted into a corresponding hole in the plastic tower of a desktop computer.
