Sheet1 Page 1 1) What type of communication is used in a TV remote? a. Half duplex b. Full duplex c. Simplex d. None of the above (a) 2) Which layer do routers function in? b. Physical, data link and network (b) 3) Which type of situation is Ethernet NOT suitable in? a. Hosts send data sporadically in bursts b. Most of the times the hosts are idle but sometimes they all want to transmit data at the same time c. Hosts do not send data most of the time but they send data sometimes. (b) 4) A 4kHz Analog signal is to be transmitted such that it obeys Nyquist's Theorem. The quantization is done such that after quantization 1 byte represents each sample. what will be the minimum data rate required to carry such a signal? a. 6Kbps b. 64Kbps c. 128kbs d. 32Kbps input signal = 4KHz Nyquist theorem (padha tha engg mein) says that for faithful reproduction back from digi to ana, sampling should be done at a sampling frequency is 8KHz samples being input to the quantizer at a rate of 8Ksamples/second each of these samples is represented by a byte 8Ksamples/sec * 8bits/sample = 64Kbps 5) If a host knows only it's MAC address. What protocol can be used to identify it's IP address? a. IGMP b. ICMP c. ARP d. DHCP (d) DHCP 6) ARP protocol is used to identify the host's ________ address given it's __________ address.
