1) Two hosts, A and B, are separated by 15,000 km and are connected by a 10-Mbps direct link. The propagation

speed over the link is 2.5 * 108 m/s. If you are sending 10-million bits of information, what is the maximum number of bits that will be on the link at any given time?

2) Suppose that there are four routers between a source host and a destination host. If a 1,400-byte message (i.e., there is no fragmentation) is sent from the source host to the destination host, how many forwarding tables are indexed?

3)Suppose that datagrams are limited to 1,500 bytes (including headers) between Source-Host A and Destination-Host B. Assume that you have a 40-byte IP header and a 20-byte TCP header. How many datagrams would be required to send an MP3 message consisting of 16-million bits?

You are working for a company that has developed a new speaker that is supposed

to reproduce any and all signals in the frequency range of 20 Hz to 20 kHz with a flat frequency response. You have been selected to test the speaker in order to verify the operation. You are supplied with a microphone that has a flat response, a perfect power amplifier, a white noise generator, and an anechoic chamber. How do you utilize Fourier transforms to test the speaker?
