Please answer that question quickly if you do understand that. 

 

1.1> Baud rate and data rate could be used interchangeably because their meanings areequivalent.True_ False_And explain:ADSL uses base band for transmission of signals.True _False_And explain:2.Describe in details at least four cri±ques of the OSI MODEL and its protocols.3.a> If a 16-level signal is sent over a 100KHz channel whose SNR=37dB what is the maximumachievable data rate? Show all your work.b> Explain why Fourier Analysis is one of the most important theore±cal basis for datacommunica±ons. There is no need to give me the formula. Just explain in your own wording.4.List and explain the four methods of framing in the data link layer. Then describe adisadvantage of each of methods.5.We have a simplis±c broadcast subnet. Suppose that ±me is divided into discrete slots, witheach host of the n hosts a²emp±ng to use the channel with probability p during each slot.a>What frac±on of the slots is wasted due to inac±vity?b>What frac±on of the slots is used for successful transmissions?
