PPT-Hubs, Switches and Bridges

University of Calgary CPSC 441 LAN Interconnection We need to break down big networks to subLANs Limited amount of supportable traffic on single LAN all stations must share bandwidth Limited length 8023 Ethernet specifies maximum cable length For 10 Mbps. To meet these increasing perform ance demands designers must pay special attention to timing delays and skews in clock signal generation syn chronization and distribution Designers face the challenge of creating a clocking system that meets tighter Traditionally bypass switches were built by using individual switchdisconnectors connected with conversion kits ABB offers a modern solution one single device consisting of three switches and no conversion kits This does not only have a high perform Suspension Bridges. A suspension bridge is a type of bridge which is built by suspending the roadway from cables attached to a master cable which runs above the length of the bridge. . They are strong and lightweight.

Q and A for Ch. 17 IS 333, Spring 2016 Intro: What is a LAN? Q: What is a LAN? A: A local area network is a layer-2 network, where any machine can send data directly to any other machine on the LAN. I.e., each packet can be addressed with the destination’s address and sent to it without any changes to the packet’s addressing.
