9: Which of the following access network technologies has a property of asymmetric transmission rates(i.e different transmission rates for upstream and downstream)?
1. DSL
2. Cable
3. Both
4. None
which of the following physical media provides the greatest transmission rate and hence is suitable for backbone links?
1.Coaxial cables
2. Twisted pairs
3. Fiber optics
4. satellite links
9)Ans:- 1. DSL
Digital Subscriber Line technology exits in both symmetric and asymmetric form. It also offers more bandwidth for downloads by sacrificing bandwidth available for uploads.
10) Ans:- 3. Fiber optics
Fiber optics is use for transmission of information as light pulse along a glass or plastic or fiber. Fiber optics is used long distance and high performance data networking . Hence, it is suitable for backbone links. (backbone cables are used to provide interconnection between telecommunication rooms, entrance facilities, equipment rooms or buildings.)
