Commonly Used Ports And Protocols

This test I think is a hard one, but if your a genius with dealing with networking and security, it should be fairly easy. If your not, you can gain a bit more knowledge of services or applications that use common ports and protocols. Some of these maybe configured differently depending on the network, but they are commonly used. (hint) protocol will be either tcp or udp and some use both. I will stop at 81 questions because there are thousands more.
