Well, in a nutshell, your computer has things called 'ports' that can run 'services'. These 'services' 'listen' for a connection(from another computer), and perform a 'service'(depends on the situation) for the other end of the connection.
For instance, by viewing this website, your computer opened a connection to answers.yahoo.com on port 80. Port 80 on the answers.yahoo.com webserver is called 'open' because it can accept connections from other computers. Anyways, you opened a connection to this website on port 80; the service listening on that port on answers.yahoo.com then recieves commands(meh...can't remember what they're really called..haven't read the RFC in a while) from your computer, and does the requested work. It then returns the output(the webpage).
Also, don't know if that's what you wanted, but please be more specific with your question.

Open ports = risk
Closed ports = secure
