Jarrod Darnall: Basically, list each node on the network, then list which services are running on each node, like routing, web, mail, FTP, etc.
Coleman Coscia: You'll probably want a router to connect to the internet, which in turn connects to a firewall, which then connects to an ethernet switch, and then has ethernet cable's going to the PC's and Servers. It can be more complex if you want.The easiest way I explain TCP/IP ports to people:Imagine the old telephone operator's switchboard represents a single TCP/IP address. A "tcp/ip port" would be one of the holes in that switchboard. For example, http (used to surf the internet) uses port 80. SMTP (for email) uses port 25, and FTP used to transfer files uses port 23. Since you know you can surf the web and do email at the same time, you therefore know that your single IP address has multiple ports that can function at the same time within that IP address.A protocol is what is used for communications between ! computer systems. Stuff like when to talk, how much to say, how do I know what I sent is what you got, that sort of thing. http (hyper text transfer Protocol), SMTP (simple mail transfer Protocol), FTP (file transfer protocol). Even TCP/IP stands for Transport Control Protocol and Internet Protocol.that's a start for you. It's alot easier than it sounds. good luck!...Show more
