From the above we can observer that, there is a one-one mapping between Protocol and Port on the server.
But on the same page (21), one more statement is like "Although it is possible to run more than one app on the same port if the apps use different protocols"

I believe it should say:
Using one server app per port, a server can have up to 65536 different server apps running (although it's possible to run more than one app on the same port unless the apps use different protocols).

If is not possible to run multiple apps on the same port using the same protocol. So, for example, you could not run FTP on port 80 over TCP and HTTP on port 80 over TCP. Make sense?
