In computer science, a port is a number - commonly used in the TCP and UDP protocols - used to distinguish different applications on a computer. Ports are also used to distinguish different data flows on one computer. For example, if I connect to a Web server, the destination port will be port #80 - that way, the destination computer knows that the data should go to the Web server, and not to some other application. And the origin port might be, for example, port #1024 for one file I get from the server, and port #1025 for another file I get from the same server.
