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. The Ethernet protocol is by far the most widely used one. Ethernet uses an access method called CSMA/CD (Carrier Sense Multiple Access/Collision Detection). This is a system where each computer listens to the cable before sending anything through the network.If the network is clear, the computer will transmit.thernet.
