Explain your decision.Compare and contrast the use of leased lines in a WAN or LAN setting. Then recommend what you would use if you were a CIO. Support your response with evidence or examples.ÿClassmates:ÿ ÿ ÿBoth DSLandÿcable high speed Internet services are available to millions of residential and business consumers worldwide.ÿDigital subscriber Line uses a sophisticated ÿa sophisticated modulation scheme ÿto pack Internet in to the same pair of copper wires that brings you your phone service .DSL ÿuses two existing copper telephone line connected to the premise and don’t tie your phone as a dial up connection does.DSL ÿconnects to multiplexers with some combination of a synchronous transfer mode ATM ,Frame Relay or Internetÿprotocol Internet ÿthrough this connection the signals are put on high speed backbone line.ÿCable Internet is a ÿbroadband Internet connection that is designed to operate through TV’s local cable by means of a modem.Cable Internet works by using TV channel space for data transmission, with certain channels used for downstream transmission , and other channels for for upstream transmission. because the coaxial cable used by cable tvÿprovides much greater bandwidth than telephone lines .A cable modemÿcan be used to achieve extremely fast access to web.ÿ ÿ ÿ ÿWith DSL there is access to both the Internetÿand phone line at the same time , it is a ÿfaster speed than dial up :and it offers an ability to choose different connections ÿbetween different connection speed and pricing from the providers.on the other side cable offers performanceÿthat is not based on a distance from ÿa providers central location;it s a ÿspeed faster thanÿboth dial up and more than likely DSL. DSLÿis not a shared connection ;It uses an existing phone lines which is often exclusive to a home or an office . more people sharing the cable bandwidth affects the network speed .which makes DSL more favorableÿthan Cable.Leased line WAN connections enable you to link your business ‘s sites together .your leased WAN don’t have to be the same size .besides linking yourÿ,offices together, your WAN would increase resilience of your business.Leased WANÿlines can be used to carry phone calls .Calls made over leased lines are usually cheaper.LAN , which refers to local area network , is the name given to a computer ÿnetwork spread in a limited geographicalÿarea. .computer networks found in a limited area such as a home ,school ,office building can be identified as local area network . both wired and wireless media can be used for interconnections where Ethernet over twisted pair and Wi-Fiÿare the most used methods for LAN .Since limited to a small Area , the cost for the network is relatively low.Also, the speed is high.Being ÿa CIO I will recommend the LAN because ÿit carries more advantages than WAN ieÿthe amount of errors in LAN is much less than the amount in WAN , Its easy to troubleÿshootÿin LAN than WAN,the maintenancesÿcost for a LAN is much lesser than maintenance cost for WAN and lastly the congestion in LAN is typically lesser than the congestion in a WAN.ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿ ÿReferenceselectronicsÿdesign.com/communication s/what-s-difference -between -cable -and -dsl-broadband-accessdiffer.com/different /cable_vs_DSLDifferencebetween.com/difference -between -lan-and-vs -wan
