Document Summary

Review questions: explain the key differences between local area networks (lans) and wide area networks (wans). What are the implications of these differences as relates to service and support and economics/budgets. Local area networks (lan): operates entirely on customer premises an office suite, office building, or other property owned by the company or enterprise. The enterprise must service/maintain every aspect of the lan. Ethernet; layer-2 technologies within wans are more costly technologies than. Wan carriers charge monthly fees to enterprises for the wan capacities/connections and services. In wans, as distance increases, the price of transmission increases. Lans provide 100mbps or 1gbps, home wan speeds more typically vary from 1mbps to 50mbps, and these speeds are shared by multiple users. Wide area networks (wan): networks that operate outside the customer premises. Wans connect different sites within an organization or transmit data between organizations. Wans are typically designed with guaranteed performance capacities based on physical connectivity from the customer to the carrier.
