In this video, I delved into the concept of protocols, focusing on HTTP as a widely used example. I explained how protocols act as a common language between machines for effective communication. By breaking down the HTTP protocol structure, I demonstrated how clients initiate requests and servers respond accordingly. Additionally, I showcased a practical demo using raw TCP connections to send HTTP messages, highlighting the importance of adhering to protocol specifications for successful communication. I emphasized the significance of understanding and potentially creating custom protocols tailored to specific needs.

Thank you for watching and supporting! it means a ton.
I am on a mission to bring out the best engineering stories from around the world and make you all fall in
love with engineering. If you resonate with this then follow along, I always keep it no-fluff.

Just came across this channel because my friend told me to check, this is undoubtedly one of the best programming channels out there!
No doubt the most simple and clear explanation of protocol
Never seen a better video on protocol then this!!
Nothing is more advance than basic, well explained!
Amazing! Would love to see an RFC explanation in depth from you 😄
hahah. I did one for REST, but very few watched it :) kya hi kare!
Such a nice explanation with a simple example. You are a good teacher!! Keep doing more of it. Thanks for making this one :)
Thank you Ashish 🙌
i didnt know this, every developer should know this.good video.thanks
Great Video Sir! Can you explain how REST and SOAP rely on it or developed based on it?
Great Video Sir! Can you explain how REST and SOAP emerged out of it?
Very easy to understand and follow. Next time I'll have an answer if somebody asks me what is a protocol :p
Thank you Kriti 🙌
Beautifully explained !!
Thank you so much, had an idea but you clarified it more!
Awesome explanation. Lot of concepts got cleared. What software you use to create this presentation?
Thanks, Arpit
Great video, Arpit.
great in-depth explanation. amazing.......
Please make more videos on Internet/Web fundamentals
Sir i am following you since a few months. I have a really important question to ask
You mentioned many times that you have built some core projects, not some web or app, like using some FUSE, PINTOS etc.
It sounds great but at the same time is overwhelming, like I don't know how to go about them.
You have also answered that just start coding, but please can you explain a bit about what can be a starting point and how should be proceed. I know you don't believe in some roadmap or like that , but any advice from you in that direction would be really appreciated.
And I am now in final year, looking for placements. Now i think i don't have so much time to do no-fluff engineering
Placements are important, focus on what matters the most today. Everything else can wait.
@@AsliEngineering But still sir please answer the above quesn too
I am not Arpit, but my answer would be that start small. If you've been following Arpit, you would know that he has always advised us to find small opportunities for implementation. So instead of jumping into implementing a file system right away, focus on how you can build the tiny stuff first. For example, how about writing a scheduler? You can not bench press 100 on the first day, it's going to take a long time to build that muscle. Likewise, it's natural that you would find these projects overwhelming if you aren't habitual of getting your hands dirty.
Defining API can be considered equivalent of defining our own protocol.
i don't think so. you follow a protocol to write your api.
Lol
@@thisisamishytIts kind off high level example
Nope. When you Define API, you just define endpoint. When client hit that API, it comes via PROTOCOL to your endpoint.
Noob engineer
Thanks, it's a great explanation!
I have one question: When you establish a manual connection, does that TCP connection stay alive until you manually close it by using Ctrl+C? What happens in the case of requesting using curl or a browser? Does it close the TCP connection as soon as the response is received?
At 10:12, is the server hit after mentioning content length as 28? I always assumed HTTP requests are fully prepared on the client side and then the connection is established with the server and the server receives it in one go and doesn't have to wait!
To answer my own question, for anyone else wondering the same - a TCP connection is established in the very beginning through a TCP handshake and the connection is kept open throughout the request-response life cycle.
Can you please make a video on Gorilla DB as well. I am facing some difficulty in understanding Gorilla DB research paper.
thanks for these videos.
also liking and commenting on this video, so that the algo pushes more such videos on my feed. Please youtube.
Hey arpit I love your videos please can u make series on golang backend
Great video sir.
Can you please show me how to use p5.js to create an algorithm that draws the Sierpinski triangle. where it is possible to select the number of generations before the program is run? :)))
Thanks Arpit.
Can you make a video on GRPC as well? GRPC does not have GET/PUT etc etc but still is http 2.0. How does that work?
Grpc is built on top of http2. So the payload that is sent in message comtains the required metadata that a grpc server can interprete and understand which method to call and which arg. I have a video on RPC in my channel which can be a good starting point for you.
Thanks
Need one on TCP as well
Hey Atpit, one question, At 6:22 you said that the error was emitted by golang server. But, how did the request reach golang server without passing an hostname
The request went over TCP. Host header does not mean it needs to go there. It is just a cosmetic header which tells from where the request is originating.
Most framework does not require it. Try doing this with flask. You will see it does not throw error due to missing host header
Just to understand better, so we used the netcat to establish a TCP connection on the localhost address on the 1729 port. But the Host header is part of the Request Header, which is specific to the Go http server, right?
@@devsami Yes. It is Go's default HTTP server that returned bad request if it did not see hot header. Flask does not give that error.
Arpit, do have a discord channel?
nope.
Can you please please make an indepth video on CDN(content delivery network )
There are some topics that I go in depth in my courses and hence cannot put them out on YT. CDN is one of them.
We spend about 2 hours understanding it end to end. Apologies but I hope you understand.
@@AsliEngineering no problem. may be an introductory video
Very nice
gold stuff content
Liking before watching
❤️❤️❤️
This is Liquid Gold.
Content is good but instead of explaining http methodologies are, i would have appreciated what exactly http protocol is, like for ex: ambiguity == having multiple meanings making it clear.
For ex: im in a interview they ask me what exactly is http protocol is, i say, it have these specs (get, post, ), client initiates the request, content is served etc...... they will be like no that is what http means that is again a method of http, what exactly is HTTP? me -> :( ,
Again no offence arpit, i love the way you to teach, you are an absolute SME.
it is a protocol. a standard of communication using which a client and server can talk to each other. http is hyper text transfer protocol. you should be able to find what hyper text means, transfer and protocol must be clear now.
Promo sm 😂
Please get rid of the lines where u write.
