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.
