True or False? If transmission channels become virtually error-free, the data link layer will no longer be needed. In the next question you must provide 1-3 sentences to explain your answer.

Consider the figure and assumptions in the image for the ARQ problem. Suppose there are no errors. What is the maximum possible window size, Wmax (in number of frames), that can be used for the proper exchange of frames between Node A and Node B? Assume the frames have a 2-bit sequence number, i.e., the frames are counted as follows: F00, F01, F10, F11, F00, F01, F10, F11, etc. If you cannot determine the maximum window, just write Wmax = 2 as your answer. Points for wrong W will be deducted only for this question. Answer Format Wmax = [maxframes] frames (Integer)  

Which encoding scheme, Manchester encoding or the MLT-3 encoding shown on the formula sheet, is the best for i) clock recovery, ii) dc offset, iii) reduced baud rate? In the next question you must provide 1-2 sentences each to explain your answer.  Answer format: For each block, type Manchester or MLT-3 i) The best for clock recovery is [clock]  ii) The best for DC offset is [dcoffset] iii) The best for reduced baud rate is [baudrate]
