Q1 Figure 1 shows a multiplexer in a synchronous Time Division Multiplexing (TDM) system. The bits arrive at the multiplexer is from source \( A, B \), then \( C \) and repeat the sampling in this order. One frame will take 4 bits from each source until all the bits from source A, B and C are transmitted completely. The binary from Source A and B are shown in the figure, while Source C is the binary converted from your student ID based-on modular 2 operation. 1. Draw a diagram to show the structure of each frame. (1 mark) 2. Calculate how many bits in each frame and how many frames in total for sending all the bits. (1 mark) 3. Give the output stream of all the frames. (2 marks) 4. Discuss the advantages and the disadvantages of the synchronous TDM. (1 mark) Figure 1 Synchronised TDM Multiplexing. Q2. Give your understanding about the Internet-based data communication. 1. Why is a layer model used in TCP/IP model? (1 mark) 2. Why did the Internet designers choose packet switching instead of circuit switching as the preferred option? (1 mark) 3. Explain the steps of a router to process the received data. (2 marks) 4. How is a packet moved from the source to destination? (1 mark)
