+Adam Paulík If no one understand this comment, the max number should be 255. But I wasn't too careful when writing a fake IP address for some of the titles. It will never be 412.

Hey, Please check the meaning of Full duplex. It means data can flow in both the directions "at the same time". Even in half duplex data can flow in both directions but only one direction at a time.
@@yolomuffins1437 no its a definition. simplex means: data can flow in only one direction half duplex means: data can flow in both directions "but not at the same time" full duplex means: data can flow in both directions "at the same time" these definitions are used everywhere where data is being transfered. So from your pc to youtube, but also from a microcontroller connected to a sensor or a interface. Its just to understand how the data can/is being transferred.
I dunno how I found you, but I have been watching your videos last 3hours in a row :D Really good job, these videos are really good and helpful thanks! Keep goin!
Good video! One confusion to clarify here is that a websocket is vastly different that an internet socket. A websocket is a protocol while an internet socket is a logical construct of ip + port number
I love how you explain the very basic stuffs. Most people talk about something and use term while assuming people already know everything. It's annoying
Great job, you are really concise and to the point. They say only when you can describe it simply you truly understand it. Thank you for this man, keep up the good work.
Hello Dave Your this video is quite impressive and simple to understand the Internet communication concepts which are otherwise so intimidating. I would like to see more such videos. What is your website where I can subscribe... Sanjiv
This video was great, thank you so much! It's very informative and easy to understand. I just subscribed to you. Can you be my networking professor instead of my current one? I searched for your other socket video, but was unable to find it.
Why is the port on the client side random if the connection is made through http/s? How does this port-picking-by-the-os work? Nevermind. I paused right before the explanation. :D
i'm describing just regular sockets here, actually WebSocket is not the right name. it's an application built on top of sockets. Http is also an application-level protocol that uses sockets to pass data. I didn't use the right naming here. Read about tcp/ip, then sockets, then http, then websocket. (in that same order if you can) Sorry about that
Not sure why it was labelled with web sockets, you didn’t talk about them at all. Should have been sockets and the internet. Don’t bother if you actually want information on web sockets.
I think he mixed concepts here. Sockets are just sockets. Any two networked items can use sockets to communicate with each other. Websockets is the concept/technology brought about with HTML 5 to facilitate socket communication from within web pages. It's an additional layer using a standardized API. You can read more about it here developer.mozilla.org/en-US/docs/Web/API/WebSockets_API

Okay seems like you are talking in general otherwise your information is misleading, we have different protocols for connections TCP and UDP. UDP is not reliable at all. So perhaps you should of been more speicifc with relibality.
it's not misleading at all...it is a 100% accurate, high level description of what web sockets are with a particular focus on the client/server relationship. If you're looking for more specificity or mention of particular protocols, why are you watching a
If you have read the first half statement of my first line "Okay seems like you are talking in general otherwise your information is misleading". And according to you this video is " high level description of what web sockets are with a particular focus on the client/server relationship" So not really sure of what are you trying to do here? but again the title of this video give me an immersion that this video is all about web sockets not a introductory to Sockets. Everything he just said is about sockets and not web socket in particular, therefore sockets in this case can be established on both tcp and udp connections. On the other hand, if the video was talking specifically about web sockets technology in depth then yes it's true that web sockets in this sense are running on TCP connection therefore reliable. Anyhow I noticed from the first 2 minutes that it's for beginners but I felt that he needed to at least mention UDP connection since beginners will be watching this video.

+Miika Hirvasmaa Thanks! Haha that's a long time. =p
I've done it for 5 hours straight today. Learning quite a bit :)
Fantastic explanation man! Exactly the type of teaching most students need: concepts reduced into very simple ideas/analogies.
Wow man, you have a gift for breaking things down so people can understand complex things. Thank you for this! Subscribed.
I know what I'm going to do the next time I go out to the Ocean.
Sharks have done that
Well done dude. One of the best videos that explain the concept of sockets! Congratulations!
"You probably go on UA-cam for a few minutes ..." - Yeah, sure. Just a few minutes :D
lol

Very well made. Im not sure how i even ended up here but, i stayed and subbed.
I love how you explain the very basic stuffs. Most people talk about something and use term while assuming people already know everything. It's annoying
Great video! It really saves my day. Keep it going Dave 💪🏻
3 things I really enjoy: Thorough yet simple explanations, Skateboard tshirts and 70'ies porn music in tutorials. Good job, man, knuckles! :D
Lol
Great job, you are really concise and to the point.
They say only when you can describe it simply you truly understand it.
Thank you for this man, keep up the good work.
Amazing !
Loved it.
Before watching it, i really knew nothing about web socket conceptually but i'm now feeling great !
Thank U.
Please keep making videos! You so much fun to learn from.
You are doing awesome video man, make sense to me a lot.
ephemeral port - new concept for me! nice!
Don't get too attached to it, it will go away.
For you, I didn't even skip the ad :D
web sockets can be used for chat box?
web sockets are used for chat
your explanation is very clear. Why don't you take some videos on designing the big system like how youtube, facebook, google docs are designed.
But since the client socket is chosen randomly, could multiple websites randomly end up sending data through the same socket?
thank you for explaining web-socket is simple way.
Hello Dave
Your this video is quite impressive and simple to understand the Internet communication concepts which are otherwise so intimidating. I would like to see more such videos. What is your website where I can subscribe...
Sanjiv
short and complete overview. thanks!
Great high overview! Looking forward to more content
Great explanation this is the information I've been looking for a longtime Thank you!
Is Websocket and socket the same thing?
Nice Video! Great info.
those finger gestures are self-explanatory when you watch it at 2x
Oh my god I loved that video! Simple but so informative 😍
Nowadays youtube uses the 443 port because of the HTTPS protocol, port 80 is for HTTP protocol
when you're looking for a video on WebSockets but you end up watching an entire one on Web Sockets lmao
Do you think one will need to learn full TCP/IP and WebSocket draft to fully inderstand the concept ?
Great video! Thank you!
thx!
What you're describing are TCP/UDP sockets. WebSocket is a protocol.
Yea, that's a good point. Not precise with the words here. Thanks.
makes a lot of sense to me, thanks
Thank you so much. This video really helped me
Thanks brother
Awesome!! subscribed! Thank you for explaining it so simply :)
good video...explained in a very layman terms
I really loved the information you told us.
Very well explained. Love your videos. :)

good work, thanks for the detailed explanation, good for a newbee
you really helped me, man. thank you.
Very well explained!
nice job on this
Great Video and nice explanation :)
thank you so much for the simple explanation!
just subscribed. good work!
awesome video!
And what is the difference between a web socket and a REST?
3:35 123.52.412.2:1337 ) Ha ha ha :) 412 :)
Yeah, I think you are right, that IP address is impossible. It should be 255 max
You are awesome , great explanation
Very well explained!!!
noob here, does the port define the protocol? or is it the other way around?
Hi man !
Thanks a lot for explanations !
Great vid, well done
you helped me, man. thank you.
very very good video!
New subbie here! Thank you 🙏🏽
Why is the port on the client side random if the connection is made through http/s? How does this port-picking-by-the-os work? Nevermind. I paused right before the explanation. :D
Bro you da MVP
I'm getting confused ;/
the short answer "Socket" mean? IP + port
is this correct?
clear explaining thnx
better use port 443 for https instead of 80?
So sockets mean IP+port?
Thanks for the info.
Awesome!
When you say Full Duplex does that mean the Websocket protocol and not HTTP correct?

Http is also an application-level protocol that uses sockets to pass data. I didn't use the right naming here. Read about tcp/ip, then sockets, then http, then websocket.

Thanks man
what is the use of http in web socket?
ok one connection to socket one for client and one for server
Not sure why it was labelled with web sockets, you didn’t talk about them at all. Should have been sockets and the internet. Don’t bother if you actually want information on web sockets.
thank you very muckh. "if you dont like my face" lol
Plz tell me how socket communication(client - server) are made?
Anyone notice the 412 in the IP address? OMG this guy need a urgent networking curse.
Thanks.This helps.
Good Video. But the music irritates me. Without music would be better.
so a socket is an ip address with a port number?ty. what is api?

thanks that was graeat
How come when I try to connect to www.reddit.com:80/ it doesn't work?
Man, how can raw bits be transferred if cables are cut??? is that truly what reliable means?
if the undersea cables are cut... the world would probably shut down
Please ,what reliable means?? suppose the problem is just in your cable
They can be transferred UNLESS cables are cut. ;)

1. UA-cam uses https not http.
2. The IP address contains a 412.
3. Is hotmail still around?
