Part A While following a treasure map, you start at an old oak tree. You first walk 845 m directly south, then turn and walk 1.19 km at 30.0° west of north, and finally walk 1.00 km at 32.0° north of east, where you find the treasure: a biography of Isaac Newton! To return to the old oak tree, in what direction should you head? Use components to solve this problem. Express your answer in degrees. \theta = 81 \textdegree west of south Part B How far will you walk? Express your answer with the appropriate units. R = Value Units

Q.3 a) 12 PCs and one server are to be connected by an Ethernet LAN. The cost of a 1-Mbps adapter is $10 and that of a 10-Mbps adapter is $100. It is required to backup 1000 MB of data from the hard disk of each PC to a tape drive on the server every day. Which of these two network adapters will you choose? Justify your answer. (5 marks) (b) A link-level protocol uses CRC-8 (whose divisor polynomial is x^3 + x^2 + x + 1) for error detection. When a frame is transferred using this protocol, 9 bits are corrupted. Can the receiver detect the error? Justify your answer. (5 marks) (c) Ten 9600-bps input links are multiplexed using TDM onto an output link. What is the bit-rate required by the output link when fixed TDM is used? Assuming that we wish to limit the average utilization of the output link to 90%, and assuming that each of the input links is busy for 60% of the time, what is the bit-rate required by the output link when statistical TDM is used? (5 marks) (d) What is the baud rate required by 10BASE5 Ethernet and 100 Mbps FDDI ring? Explain. (5 marks) (e) Assume that host A is transferring frames to host B using a sliding window protocol with a window size of 10 through a 100 km-long 10 Mbps link with a propagation speed of 5 us per km. Assume that each frame carries 125 bytes of data and the frames are numbered from 0. What is the current window size when the ACK for frame 0 is received by host A, assuming that the communication is error-free? (5 marks)

7-19 The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown in Figure 7-19. The Lo Shu Magic Square has the following properties: • The grid contains the numbers 1 through 9 exactly. • The sum of each row, each column, and each diagonal all add up to the same number. This is shown in Figure 7-20. In a program you can simulate a magic square using a two-dimensional array. Write a function that accepts a two-dimensional array as an argument, and determines whether the array is a Lo Shu Magic Square. Test the function in a program. 7-20 4 9 2 3 5 7 8 1 6 15 4 9 2 15 3 5 7 15 8 1 6 15 15 15 15 15
