Q5 State whether the following statements are TRUE (correct) or FALSE (wrong). 1. The physical size of metropolitan-area networks (MAN) is smaller than local- area networks (LAN) 2. We use Cross-Over cable for connecting two devices with the same type a 3. Fibre optics can support higher bandwidth compared to wireless transmission 4. Single bit error is more likely to happen in serial transmission 5. Network physical topology concerns with how the nodes of a network are connected together 6. The TCP and UDP protocols belong to the internet layer of the TCP/IP model b State the different layers of the OSI model in order. Consider a transmission medium that has a bandwidth of 2 MHz, an average signal power of 155 units, and an average noise power of 5 units. c Determine the channel capacity. If we decide to use 80% of the channel capacity to transmit a signal, what d. should be the number of signal levels?
