Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are

PreLab 1. Describe the different between a LAN switch/bridge and a router. LAN switch/bridge operate at the data link layer(layer2) and works based on the MAC address‚ while a router operates at the IP layer (layer3) and works based on IP addresses. 2. What is the difference between an Ethernet switch and an Ethernet hub? Which is more suitable for a network with a high traffic load‚ a switch or a hub? Explain. Ethernet switch is a store-and-forward device that operates at layer2

A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home‚ school‚ computer laboratory‚ or office building using network media.[1] The defining characteristics of LANs‚ in contrast to wide area networks (WANs)‚ include their smaller geographic area‚ and non-inclusion of leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but Ethernet over twisted pair cabling‚ and Wi-Fi are the two most
