2) Hosts A and B are on two different TCP/IP networks, Net 1 and Net2, respectively. Net 1 and Net 2 are interconnected through a router. Host A is sending a packet to Host B. Host A has both Host B's and the router's IP address. Explain
(a) How Host A determines whether Host B is on Net 1 or Net 2?
(b) What Host A does so that the packet can delivered to the router first?
3) Networks based on the TCP/IP standard employee three types of addresses: symbolic, numeric and physical. All of them are used to identify a given host (so that excludes the port number). Provide an example of each type of address? How are these addresses assigned? How are these addresses used in message transmission?
4) What is NAT, and how does it work? Use a specific example. What are the benefits of using NAT?
5) What is the difference between DHCP and DNS?
6) List at least 3 wireless propagation issues and explain?

9) What is the difference between Peer-to-Peer and Client/Server?
10) What is the email difference between Tier3 Web server and Tier2 Client Server (Micro Exchange Server)? In other words, how would they send emails to each other?
11) Explain relationship between cell size and channel size?
12) What is the difference between IPv4 and IPv6? What about their length?
13) What were the symbolic, unique and physical (MAC address) addresses?
14) How to assign Subnet IP masks?
