Question 1:
Describe the two layers: LLC & MAC, and how are they different from what is available in the TCP/IP protocol? Why do we need these two extra layers for a LAN?

Question 2:
An asynchronous device,such as teletype, transmits characters one at a time with unpredictable delays between characters. What problems, if any, do you foresee if such a device is connected to a LAN and allowed to transmit at will (subject to gaining access to the medium)? How might such problems be solved?

Question 3:
Explain why is it when a load exceeds the network capacity, delay tends to increase?

Question 4:
What is the difference between a hub and a layer 2 switch ?

Question5:
A tree topology is to be provided that spans two buildings. If permission can be obtained to string cable between the two buildings, one continuous tree layout will be used. Otherwise, each building will have an independent tree topology network and a point-to-point link will connect a special communications station on one network with a communications station on the other network. What functions must the communications stations perform? Repeat for ring and star.
