== Description ==

A port is a number between ''0'' and ''65535'' which allows a [[server]] or [[client]] to know which which application the remote connection is trying to connect.

Together with an [[IP]] (which specifies the exact computer, either [[server]] or [[client]], with which some computer is trying to connect to) it specifies the exact destination the connection must get to. It is written in the form ''IP:PORT'' most commonly.

== Examples ==

For example, [[aMule]] usually uses port ''4662''. So let's suppose your [[IP]] is ''80.0.0.1''. Now let's say some computer somewhere sends a [[packet]] to ''80.0.0.1:4662''. This [[packet]] is going to be sent to ''80.0.0.1'', which is your computer, and once there, it will be delivered to port ''4662'', which most probably will be a port where [[aMule]] will be listening, so it will get to [[aMule]]. [[aMule]] will read the [[packet]] and act depending on what its content is.

If the packet was sent to ''80.0.0.1:21'' it will also get to you, but (probably) not to [[aMule]] since [[aMule]] will no be listening on that port. If some other application is listening to it (possible some [http://www.faqs.org/rfcs/rfc959.html FTP] [[server]]), it will read its contents and act depending on what they are. If no application is listening to that port, then the [[packet]] will just fail to be delivered. Though it got to your computer, no application was waiting for it, so it will be refused.
