T-1 Lines.  Please respond to the following:

• From the e-Activity, analyze the multiplexing techniques of DSL and cable modem Internet and suggest the one you prefer. 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.

     Both DSLand cable high speed Internet services are available to millions of residential and business consumers worldwide. Digital subscriber Line uses a sophisticated  a sophisticated modulation scheme  to pack Internet in to the same pair of copper wires that brings you your phone service .DSL  uses two existing copper telephone line connected to the premise and don't tie your phone as a dial up connection does.DSL  connects to multiplexers with some combination of a synchronous transfer mode ATM ,Frame Relay or Internet protocol Internet  through this connection the signals are put on high speed backbone line.

 Cable Internet is a  broadband 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 tv provides much greater bandwidth than telephone lines .A cable modem can be used to achieve extremely fast access to web.

       With DSL there is access to both the Internet and phone line at the same time , it is a  faster speed than dial up :and it offers an ability to choose different connections  between different connection speed and pricing from the providers.on the other side cable offers performance that is not based on a distance from  a providers central location;it s a  speed faster than both dial up and more than likely DSL. DSL is 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 favorable than 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 your ,offices together, your WAN would increase resilience of your business.Leased WAN lines 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  network spread in a limited geographical area. .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-Fi are 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  a CIO I will recommend the LAN because  it carries more advantages than WAN ie the amount of errors in LAN is much less than the amount in WAN , Its easy to trouble shoot in LAN than WAN,the maintenances cost 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.
