What are TCP and UDP ports? How do ports relate to protocols. Where did they come from? How should they be managed?


In this video, I play fast-and-loose with Internet history, and explain the function and use of TCP & UDP ports. This was an unscripted presentation, so there are multiple mistakes. For example:
- I couldn't remember what port was used by early database programs.
- I overstate the role of IANA in the development of Client/Server computing.
- I accidently imply that Clients might frequently reuse the same dynamic port, when issueing requests to different servers.
- While discussing the Tower of Protocol Babel, I say: "..a really good Internet program..", instead of ".. a really good Internet programmer.."

- I failed to clearly state that only Client activity uses up dynamic ports.

- I say "security programs" instead of "security problems".
- I understated the difference between the Home and Server editions of Windows.
- I have NO idea what port may be used by a Hue Lightbulb service.
- At about 35 minutes in, the rope slips off, and I start wandering out of frame.
