If a network address is thought of as a physical address for a building then a port would be a room within the building. THe function of a port is to allow software to listen for or send out communication that is specifically related to it's function. For example, most internet (http) traffic is on port 80, FTP (File Transfer Protocol) sends and listens on Port 21, other services use other ports. This allows a single computer with a single IP address to be both a web server and a file server.

How do i wire a laptop through a router to the internet?

first, make sure the router is wired to your dsl/cable modem (network cable is pluged on your router's internet port & the another of that goes to the port of your modem). Get another network cable, plug it to your laptop (there's one or two socket that fits that network cable on any side of your laptop), then plug the other end of the network cable to any port numbers of the rtr.....hope that'll help! ;)
