Establishing Connections With TCP's Three Way Handshake | Network Fundamentals Part 8

Establishing Connections With TCP's Three Way Handshake | Network Fundamentals Part 8
TCP is connection-oriented, while UDP is connectionless. TCP achieves this with a process called the three-way handshake.

This is three messages between the client and server, which use the SYN and ACK flags in the TCP header.

There is a corresponding process when closing the connections. This time the FIN flag in the header comes into play.

And in other cases, the RST flag is used. This is in the case of an error, which can help with troubleshooting.

In the next video, we’re looking how TCP manages errors, and how it uses a process called ‘windowing’

You have no idea how much simplicity you've brought to every thing that has been going on... You're the best!

[benkeefe]

I really do appreciate this kind of free education. Thanks for the great content!

[brianfrancis]

Clear and concise explanation. Well done.

[abdallanofalable]

Great series, you do know how to explain the complicated ideas in a brilliant way.

The quizzes answers are your way to thank patrons, I subscribed to patrons mainly not for answers but rather it is my own way to say Thank You!

[brianmisasa]

You did a great job explaining the concept

[sportsboy]

you describe it perfectly 10 on 10. awesome video presentation as well.

Nicely explained..i m going to watch all your videos now.. Thanks

[samaradryburgh]

Great video - Ive been reading this as explained and described in a textbook but you brought it to life so clearly! Thanks :)

[TrickyMicky]

Thanks for all this great information. I have looked at various sources online and have tried to teach myself but none of it made sense. This series on yt along with the quizzes and bits on patreon are brilliant!

[manikandanm]

Great job bro.Thanks a lot..even paid courses don't teach like this....

[trendyniro]

Thank you sir! very easily explained without confusion!

[linkedprosperity]

Very helpful video TCP/IP function gracias

[xinli]

Thanks. I love your video.
But the SYN, ACK number for the three-way handshake is wrong. Please check.

Quiz #1 :
connection oriented : device will start a connection to another device, they will agree to form a connection and set up parameters.
connectionless : the device just starting sending data, no agreement between them.
TCP is a connection oriented.
UDP is a connectionless.

Hi. I love this series! I've signed up with Patreon to access the quiz answers and such. I'm looking for the Study Notes for the lower level parts. I can only see Part 1 and Part 26 when I click on Study Notes on the site. Where can I find these? I'd like to be able to print the notes all the way back to part 3. THANK YOU!

[Foword]

Great video!
You're doing great job.
In my job we have firewall and we're getting some drop TCP connection with Logs like first packet isn't sync.
Can you explain what can cause this problem ?
Thank you again !

[Luisofo]

Aren´t sequence number different for the host and the client?

[AdityaDahiya]

By a connection here, do we mean a computer with a router/modem or a modem with the ISP?

[KenSherman]

Can I just establish a connection with you via a 2-way handshake for your work on this video? "Establishing Connections With TCP's Three Way Handshake" was engaging.
