A network port is essentially a number assigned for interaction with a given
service or class of services.
Ported software is software that has been converted from one type of system to
another, for example FTP has been ported to MS-DOS, Windows, and OS/2 (and
MANY others) from UNIX.
The Design and Implementation of the 4.4 BSD Operating System from Addison
Wesley is probably the best single resource for finding out what things are
and how and why they work.
I've also seen UNIX glossaries in university book stores, which might be your
best bang for the buck.
The 4.4BSD Manuals (5 vols.) are, of course, a good resource but must be
browsed to be useful since the indexing is less than comprehensive.
And occasionally a command like "apropos port" will lead you to quick online
answers.
