Baldeo Persaud NT 1210 Unit 5 Assignment 1 Ethernet LANs: A collection of devices, including user devices, LAN switches, routers, old hubs, and cables, all of which use IEEE Ethernet standards at the physical and data link layers, so that the devices can send Ethernet frames to each other. 802.3: The name of the original IEEE Ethernet standard, as well as the overall base name of all IEEE Ethernet LAN working committees. Fast Ethernet: The informal name for one particular Ethernet standard, originally defined formally as 802.3u, which was the first Ethernet standard to surpass the original 10-Mbps speed to run at 100 Mbps. Gigabit Ethernet: The informal name for one particular Ethernet standard, defined formally in 802.3z (for fiber) and…show more content…
Wireless-only LAN edge: A campus LAN design term referring to campus LANs with only wireless connections between end-user devices and APs, and no wired Ethernet LAN connections at the edge. Wired/wireless LAN edge: A campus LAN design term referring to campus LANs, with the edge of the LAN having both wireless connections plus wired Ethernet LAN connections. Shorthand name (IEEE): The term for a type of name for IEEE standards. These names begin with a speed, list “BASE-” in the middle, and end with a suffix, for example, 10BASE-T. Edge switch: In a campus Ethernet LAN design, this term refers to the Ethernet LAN switch to which the end-user devices connect. Duplex: A networking link that allows bits to be sent in both directions. Half duplex: A networking link that allows bits to be sent in both directions, but only one direction at a time. Full duplex: A networking link that allows bits to be sent in both directions and at the same time. Straight-through cable: A UTP cabling pinout in which the wire at pin x on one end of the cable connects to pin x on the other end of the cable. Crossover cable: A UTP cabling pinout in which the wires in a wire pair connect to different pins on opposite ends so that one node’s send logic connects to the other node’s receive logic. In Ethernet, pins 1,2 connect to 3,6, and pins 4,5 connect to 7,8. Ethernet header: A data structure that an Ethernet node adds in front of data supplied by the next higher layer to create an Ethernet
