How TCP and UDP Work | Network Fundamentals Part 7

How TCP and UDP Work | Network Fundamentals Part 7
TCP and UDP are the transport layer protocols that are used to get data from one application to another.

They have several common features, like port numbers (the network address of the application), headers, and multiplexing (allowing more than one application to access the network at a time).

But, they also have several differences. For example, TCP is connection oriented, while UDP is connectionless. TCP is ‘reliable’ while UDP is ‘unreliable’.

But if TCP has more features, why use UDP at all? The answer may surprise you!

In the next video, we’re looking how TCP establishes connections, sometimes called the ‘three-way handshake’

Quiz # 1 Which Protocols use each of these headers? TCP & UDP
Quiz # 2 What is a socket used for? The sockets are used to identify which application to the network data belongs to.
Quiz # 3 What detail contained in the socket? 5 tuple; Local IP; Remote IP; Local Port #; Remote port #; Protocol (TCP/UDP)

Regarding random source port numbers, you said "Ports are like addresses for applications." Nice! [Unique port number per process - Awesome.]

Dude these videos are excellent! Way more interesting and informative than my CSE310 class 😂

[HimanshuSharma]

One of the best lectures on networking, what a shame that so few people have watched them.

[newhampshireknits]

Ty these videos are so much more clear than my textbook!

[landro]

Why so few views? Thanks for the knowledge bro keep up

[paskahlisanjasprabowo]

Really appreciate your work. It helps a lot to understand what seems complicated to me couple years ago when I was studying this from a text book. Keep it up! Everyone will love it.

[kralub]

you just got me a degree sir. this is such a valuable video

[ryan-boxi]

Thanks for the clear and lucid explanation. You deserve more likes

[SaifUlIslam-dixv]

This is a brilliant series for people like me that like architectures, design, and a general high overview instead of caring about wires too much in the process.
Thank you for your hard work!

[azizahnur]

Really appreciate your videos sir! Thanks alot.

[siddcfc]

Very well explained.. unique piece of content on internet. Many thanks !!!

[brianmisasa]

Excellent video, would have loved if you touched on the Fragment offset more and the link between it and MSS and MTU and with a little bit of calculation

[shrutikanikhar]

Your videos are amazing. Very helpful, thank you.

[sarfarazalam]

Great video, learnt alot from your videos in last two days. Thank you :)

[rushichampaneri]

thank you for all these information and I love your videos

[paulzedrickmadrona]

Really good content. Please keep it up

[Lvnxrr]

Thank you so much this is amazing so far

[markarca]

1:55 - Those ports are also called ephemeral ports.

[solo-angel]

Awesome video, great presentation, thank you!!!
