[@pranab091]

This is great man. Need more content like this. Understanding the different web technologies is great.

[@alex_blue5802]

Concise and simple explanation. I love the whiteboard instead of a prepared powerpoint. It feels much easier to follow somehow.

[@codingstation7741]

Recently discovered your channel. You teach really good!! I wish I found this channel a few years before.

[@arogyabichpuria3262]

loved it, keep'em coming covering these mini topics, provides the "aha" moment.

[@NadaII]

Love that you just keep the Ring of Power on all your content.

[@pieter5466]

Good explanation on the relationship and establishment of a TCP connection, HTTP requests, and Sockets.

[@karanb2067]

For a long time HTTP and websocket were the same to me... Thank you for clarifying the difference

[@TheTobeyGaming]

Great explanation, i really like the letter vs. phonecall example, because it really helps to understand it 😄

[@vinoltauro9160]

very clear and concise. Thank you !

[@singmantkpss]

wow crystal clear intro for me as a newbie. thx!

[@lucianocavallo10]

Excellent video, very well explained, and easy to understand or refresh the protocols topic. Thank you very much!

[@manojdewangan7534]

Thanks for explaining these concepts in very simple way. I would suggest to add real use cases of these concepts so that we can relate it.

[@hackingsimplifiedinmalayal144]

Great content and crystal clear explanation👍

[@Shakas420]

Great explanation. As always!!

[@jakegica2524]

Very clear explanation. thanks mate

Wonderful video. Thank you

[@mayurdugar03]

Well explained. Thanks! :)

[@mattaldrete8144]

This was very helpful!

[@DevOpsLabs4Me]

Great explanation of web sockets.

[@ricardohincapie1537]

Great video. Thanks!

[@cordelldev]

Great video, thanks for this!

[@abhishekvishwakarma9045]

Great, Informative 👍

[@VijayKumar-pd7vv]

Now this is a quality content

[@paprikawurstify]

very good video thank you, helped me a lot to understand websockets and also http again :)

[@supersoniq4102]

You made this complex concept become like ABC

[@praneethreddy904]

you have great knowledge

[@nitinpathak1826]

Great explanation 👍🏼

[@user-ql5ei4sc2h]

Great explaination...

[@SilentSolution]

Thanks for explaining

[@SignUpCrmTesting]

Very Helpful

[@prataprudradeva4713]

Great explaination please share some use cases for WS.

[@cdb8987]

Great explanation

[@Avoid0]

Great video 🔥

[@Sonu-tg6tg]

Thanks for such awesome videos, always waiting for your new videos, will be glad to get t-shirt giveaway

[@shrestha0144]

I really love your videos

[@PraveenKumar-ft2kr]

Nice explanation :)

[@YOUdudex]

Nice video, please bring the scaling web socket video 😁

[@vishalpatil7994]

Thank you mehul sir

[@alexandruhutu3067]

Really nice video!

[@hartajsingh1554]

@codedamn please try to use ring light on higher angle than your camera so that we would not see that reflection of light

[@krishnendudasgupta3397]

Great One Sir :) :)

[@pranavbhat29]

1:19 - Network Layer " decided which physical path the data will take ". Isn't it logical path? Isn't the case that Network layer/Layer 3 ( IP ) is responsible for logical addressing, while layer 2, or data link layer responsible for physical addresses ( like the Medium Access Control or MAC addresses which are 48 bit numbers resolved using ARP ? )

[@trustingod0]

Great video

[@justcurious1940]

Finally I get it.

[@sterin7279]

thankyou

[@abhijithm7179]

In case of microservices architecture, say I have a process A and process B. Now, Process A needs to continuously ask for some data from Process B. In this case, horizontal scalability issue does not come into picture. Do you think web socket communication is suitable in this scenario.?

[@shivdix]

Nice

[@ridl27]

ty

[@brajeshanokha1343]

Video is full informative, thankyou for such videos. Please remove the animation (folded paper) from behind the images, it distracts concentration.

[@Rayrockny]

Hey did you ever do a follow up video on scaling? Would it illogical to design a live chat for millions of people using websock?

[@amanagarwal2022]

Any resource on how to use websocket and get authentication and authorisation done??

[@dempseyroll96]

if HTTP(a protocol because hyper text transfer protocol) part of TCP (Transfer control protocol) then is web socket a protocol as well?

[@MrRuchir23]

Great explaination , love these types of video Thanks @codedamn

[@omairkhan1355]

bro tell me can we establish a ws connection with IRCTC

[@kishalayray7570]

Make a video on webhook With project

[@matlepak9694]

so is a websocket essentially a TCP connection that stays on?

[@lakshman587]

COMMENTED FOR T SHIRT GIVEAWAY!! :)

[@hamaed19]

👍👍

[@kehan6252]

So in a simple way, HTTP sends a request and then receives a response. Then the connection is closed. Web Sockets constantly send and receive messages and only cut off if the user/server wants to.

[@matthayden1979]

If both TCP and Websockets establishes a two way communication, what is the difference between them?

[@chirag_ccp]

HTTP and Web Sockets both run on top of a TCP Connection. We cannot compare TCP with web sockets because Socket runs over TCP. TCP allows two-way communication by default but HTTP being stateless works on the request-response model. On the other hand, Sockets are stateful so they have duplex(two-way) communication.

[@codingdesires]

Do you edit your own videos man?

[@MSS_MANIKANDAN]

Light is distracted 🙂

[@pratyushrao7979]

No you are distracted by the light

[@hsngsoftware4380]

Can you please show it in code ?

[@trustingod0]

When is it more beneficial to use web sockets ?

[@matthayden1979]

used in chat or messanger applications

[@aniketyadav6009]

Please provide in depth explanation, this video is not enough to get clear idea of a topic

[@harshitgoyal19]

To be honest, I am here for the GIVEAWAY 🤦‍♂️

[@dilipkk255]

Always assume a layman watching you and start

[@joanestradaramos1541]

i think you re confused about what's half duplex and full duplex

[@jayak3768]

Sorry doesn't address the depth of what closing a channel really means and when another channel is established what are implications.

[@saidakhmedagitaev]

I am not trying to be picky, but the music in the background is really distracting

[@aniketyadav6009]

Audio quality is poor

[@exe.m1dn1ght]

wtf you are explaining very confusing , so http connection close but tcp connection remain wtf is that ? http is in application layer and tcp is at layer 4 so how one can be close and other is open you are confusing !!!!

[@dhruvabhattacharya]

WhatsApp use web sockets.

[@mysoregopinathshantanu8800]

May the like be on this comment.

[@vcbcs2310]

you explained nothing . total time waste.. you are making just fool

[@purpinkn]

You don't even bother to move the light. So the whole time I'm starting at a ring.

[@toranekosama]

is so great

[@Naz-yi9bs]

Amazing thank you for great explanation.
