Rating: 4.0; Vote: 1
Today, we're going to talk about how the Internet works. Specifically, how that stream of characters you punch into your browser's address bar, like youtube. com, return this very website. Just to clarify we're talking in a broader sense about that massive network of networks connecting millions of computers together, not just the World Wide Web, which is a portion of the Internet, and our topic for next week. Today, we're going to focus on how data is passed back and forth - how a domain name is registered by the Domain Name System, and of course how the data requested or sent gets to the right person in little packets following standard Internet Protocol, or IP. We'll also discuss two different approaches to transferring this data: Transmission Control Protocol, or TCP, when we need to be certain no information is lost, and User Datagram Protocol, or UDP, for those time sensitive applications - because nobody wants an email with missing text, but they also don't want to get lag-fragged in their favorite first person shooter. Want to run traceroute on your computer? See directions below. Remember you can replace dftba. com with whatever website you want! Traceroute on Windows 1. Press the Start Button 2. Type CMD and press Enter 3. In the Command Prompt type tracert dftba. com Traceroute on Mac 1. Click on the Go drop down menu 2. Click on Utilities 3. Open Terminal 4. Type traceroute dftba. com Traceroute on Linux 1. Open Terminal by typing CTRL+Alt+T 2. Type: traceroute dftba. com

The video is totally worth watching!
Now i get it:
IP - is simply what and where to send
UDP - on top of IP provides ports and packaging but does not ensure the delivery, just informs when the data is corrupted
TCP - on top of IP also provides ports and packaging, but insures the delivery (thus increasing the network load)

This is exceptionally well done. Brilliant animations and love the discussion on abstraction (used a lot in CS topics and something that can add confusion at first but eventually becomes super helpful and you get why its done so much. Gonna watch all of your vids now. Cheers.

I-m so so sick of English people calling a router a rooter. She can pronounce traceroute correctly and route but some how they can-t pronounce router. Every time I hear it, my head explodes. Excellent series very informative but stop saying roooooooter!

Jokes on you- I didn-t stream this. I sent someone to download this video, burn it on a disk, then play it for me off an old portable DVD player. Now he-s writing this comment for me. Checkmate, computer lady.

At 8: 45, when I do that, I get a different message:
This site can-t be reached
ldfkgdofg. com-s server IP address could not be found.
Anyone care to explain why and how it is different?

Two Professors with PhDs in computer science spent 6 hours in lectures trying to explain this in my Master's lectures. You guys did it in 12 mins, phenomenal!

This video sums up my entire networking course in a thousandth of the time. Truly amazing stuff, I absolutely love the level of detail that goes into these videos!

These videos would be great if she actually slowed down in her talking, she just goes of rambling with no break or breath in between, it's rushed and unnatural.

Good video, but I have no idea why so many of the narrators on videos like this rush through the explanations. Slow down. People are learning.
