2. For each of the following, write the ONE correct answer. a) TCP/IP layers are Internet (I), Transport (T), Application (A), Physical (P), Network Interface (N). Which layer deals with modulation in WiFi networks? The layer whose header contains the source MAC address is Answer= Answer= b) The leftmost and rightmost bits in a byte are MSbit and LSbit respectively. For the 2 bytes 10000000 00000001, assume that the first byte is MSbyte and the second byte is LSByte. Assuming that bits are transmitted from left to right, write the transmission order that is bit big endian and byte little endian: Answer= c) Let TP=unshielded twisted pair, CC=coaxial cable, F=fiber, L=lasercommunication. Which of these media Uses a shield for limiting interference Achieves the highest bandwidth across long distances Answer= Answer= d) Of FDMA, CDMA, TDMA and SM (statistical multiplexing), which method is multiplexing primarily based on in LTE networks? Answer= e) Which particular form of FDM is used over optical fiber to achieve very high bandwidth? Answer= f) Of STS-1, STS-3, STS-12, STS-24, STS-96, which one has twice the rate of STS-48? Answer= g) A 4-PSK scheme is replaced by a 64-PSK scheme. By what factor is the data rate multiplied by? Answer= h) Max and min frequencies are 8 KHz and 3 KHz. What is the analog bandwidth in KHz? Answer= i) If a system operates at 1000 baud and uses 16 signal levels, what is the bit rate in Kbps? Answer= j) What is the samples/sec rate in KHz to digitize a signal with highest frequency 10000 Hz? Answer=
