1. The Network and Transport layers are where the protocol suites TCP/IP reside. This suite of protocols is critical to the operation of the Internet and organizations as we know them today. Do some research via the DeVry library, the Internet, and your textbook, and list and discuss three TCP/IP protocols. What are the primary functions of the Transport and Network layers? What protocols do you use each day?
2. In order to understand a LAN, you need to understand all the parts involved in constructing one. Discuss each of the components of a LAN as described in the textbook and in your research. What are the current standards for each of these components? What improvements are on the horizon? What role does ethernet play in today's LANs?
3. What are the two most important network-layer functions in a datagram network? What are the three most important network-layer functions in a virtual-circuit network?
4. What is the difference between routing and forwarding?
5. Do routers have IP addresses? If so, how many?
