Design a small network connected to the Internet. Five or six computers should be enough. Think about servers you might need, such as mail, web, dns, etc. What about a print server? How will you connect to the Internet? Will you use wireless? What about a firewall? You need to prepare a diagram that shows how everything is connected and write up a brief description of the diagram explaining what components you chose, why you chose it and what it is for.

For this assignment, you will create a basic network diagram and IP scheme for a small network. The diagram must contain network elements labeled as a network switch, router, firewall, and internet (or WAN). Additionally, you will need to create a simple IPv4 addressing scheme for 4 different sets of hosts on the network. Your subnets should be properly sized for their uses (IE you must have enough addresses for the hosts, but not too many addresses to be wasteful.)...
