1. Calculate the length of time it takes for a signal to pass down an Ethernet bus that is 300 m in length, assuming the velocity factor of the cable is 0.66.
2. For the Ethernet bus in problem 1 and a communication rate of 10 Mb/s, calculate the total number of bits that would be sent by each station before it detected a collision if:
a) both stations begin to transmit at the same time
b) one station begins to transmit at the first possible moment such that its transmission would not be detected by the other station before it began its transmission
3. Discuss the advantages and disadvantages of shorter and longer packets for different link error rates and different types of data.
4. How many addresses are available in IP version 6? Express this as a decimal number in power-of-ten notation.
