Have you ever explained TCP and UDP to someone, and gone through all the cool features TCP provides... and they come away thinking UDP sucks?

Yea... me too!

This prompted a video that speaks specifically to UDP, and why it doesn't suck =).

What if I told you that you could understand 90% of TCP with only 12 key ideas?

That is how I (attempt to) explain TCP in this recent video:

youtube.com/watch?v=JFch3c…

Sequence numbers, acknowledge numbers, window size, three way handshake... All this and more.
