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).
A router is a device that allows multiple devices to connect to a network. It will have several Ethernet ports to which one device per port is attached. For instance, in a home network, various desktop computers, laptops, printers, scanners and CD/DVD drives may be connected through an Ethernet cable to the router.
