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 ? )
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.?
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.
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.
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 !!!!
Start learning Full Stack Web Development with codedamn: cdm.sh/fullstack
Concise and simple explanation. I love the whiteboard instead of a prepared powerpoint. It feels much easier to follow somehow.
Love that you just keep the Ring of Power on all your content.
For a long time HTTP and websocket were the same to me... Thank you for clarifying the difference
This is great man. Need more content like this. Understanding the different web technologies is great.
Amazing. i have my interview tmrw and this gives a quick overview. thank you
You made this complex concept become like ABC
wow crystal clear intro for me as a newbie. thx!
Great explanation, i really like the letter vs. phonecall example, because it really helps to understand it 😄
Good explanation on the relationship and establishment of a TCP connection, HTTP requests, and Sockets.
loved it, keep'em coming covering these mini topics, provides the "aha" moment.
very good explanation
Thank you, great explanation!
very good video thank you, helped me a lot to understand websockets and also http again :)
Great explanation
Great explanation of web sockets.
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.
Great explanation 👍🏼
you have great knowledge

Very Helpful
@codedamn please try to use ring light on higher angle than your camera so that we would not see that reflection of light
Nice explanation :)
Very clear explanation. thanks mate
Great explaination...
Recently discovered your channel. You teach really good!! I wish I found this channel a few years before.
Thanks for explaining
Excellent video, very well explained, and easy to understand or refresh the protocols topic.
Thank you very much!
So much informative , keep it up bro
✌️ 😀✌️
Video is full informative, thankyou for such videos. Please remove the animation (folded paper) from behind the images, it distracts concentration.
Wonderful video. Thank you
Now this is a quality content
Great video. Thanks!
Thank you mehul sir
Great, Informative 👍
This was very helpful!
Great explaination please share some use cases for WS.
Great video, thanks for this!
Amazing thank you for great explanation.
Great explanation. As always!!
Really nice video!
very clear and concise. Thank you !
Well explained. Thanks! :)
Nice video, please bring the scaling web socket video 😁
Great content and crystal clear explanation👍
I really love your videos
Finally I get it.
Thank you for valuable content ❤️
Great One Sir :) :)
Light is distracted 🙂
No you are distracted by the light
if HTTP(a protocol because hyper text transfer protocol) part of TCP (Transfer control protocol) then is web socket a protocol as well?
Great video 🔥
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.?
Thanks for such awesome videos, always waiting for your new videos, will be glad to get t-shirt giveaway
Great video
bro tell me can we establish a ws connection with IRCTC
thankyou
Any resource on how to use websocket and get authentication and authorisation done??
Nice
so is a websocket essentially a TCP connection that stays on?
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?
If both TCP and Websockets establishes a two way communication, what is the difference between them?
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.
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.
COMMENTED FOR T SHIRT GIVEAWAY!! :)
ty
When is it more beneficial to use web sockets ?
used in chat or messanger applications
Make a video on webhook
With project
Do you edit your own videos man?
Please provide in depth explanation, this video is not enough to get clear idea of a topic
Can you please show it in code ?
Http protocol stateless horizontol scaling tcp connection duplex handshakes get/abc 2 way communication websocket tcp l4 dual channel stateful after handshake multiplr channels not allowed eebsocket not horizontally scalable
👍👍
i think you re confused about what's half duplex and full duplex
To be honest, I am here for the GIVEAWAY 🤦♂️
Always assume a layman watching you and start
I am not trying to be picky, but the music in the background is really distracting
May the like be on this comment.
Sorry doesn't address the depth of what closing a channel really means and when another channel is established what are implications.
Audio quality is poor
WhatsApp use web sockets.
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 !!!!
you explained nothing . total time waste..
you are making just fool
Great explaination , love these types of video
Thanks @codedamn
is so great
Amazing thank you for great explanation.
