The same computer can have several programs related to the network. Therefore they get one or more ports each. This is used e.g. when another computer wants to talk to a certain program, and then asks for the relevant port.
The ports are simply numbers, between 0 and 65536. 0-1024 are special. HTTP typically uses port 80, FTP uses port 21, and email (SMTP) port 25.
