Create a matrix of five common, well-known UDP ports and five common, well-known TCP ports. For each port: [Port #], state the applicable port number (1 port # per row); [Use of Port] in plain English, give a functional description of how the port is used; [Port Service], name the service that runs on that port (usually a short name), [Secure] identify whether it is a secure communication port with a simple Yes or No, [Lab] finally indicate any labs you completed in Week 1 or 2 of this course in which you saw that port (if this port wasn't seen, enter None).
