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

Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

configuring inter-VLAN routing using the router-on-a-stick model? (Choose two.) Each subinterface should be configured with its own IP address‚ subnet mask‚ and unique VLAN assignment. The physical interface of the router must be connected to a trunk link on the adjacent switch. The number of physical interfaces on the router should match the number of VLANs. Different static VLANs should be assigned to different interfaces of the router. The router should be configured as the VTP server. 6
