I would tell you all a funny UDP joke but you may not get it.
Ill tell you a funny TCP joke. Did you get it? Did you get it? Did you get it?
lol good one
I could tell you a good UDP joke but i'm getting flooded with jokes from random people right now.
Hahahaha! Awesome!
I would tell you a udp joke, but jumbled it might get
I kindly request that you don't stop this series to allow me to procrastinate computer science work while I am leaning computer science.
Same dude same

3 years later and this comment is still relevant!
@@charlieosko4151 Of course. AI hasn't taken over yet, so we still need to learn Computer Science.
4 years later will and I'm following in your footsteps.
It's amazing that I can press a button on a controller, the signal goes through my computer, through my house and country and across the world and be decoded by someone else's computer in less time than I can even blink.
agreed
You should look into processors. the more I learn about then the more it blows my mind

And by then you've already been stabbed in the face by a 12 year old talking about your mom.

Correction:
SMTP is not used to check email. SMTP is ONLY used for the purpose of sending and receiving email messages to and from a server.
The protocols you would use to *check* your email are POP (Post office protocol) or IMAP (internet message access protocol)
The "receiving" in your statement is still confusing IHMO but yeah, I was going to say this: from an end-user perspective, SMTP is used to send emails, period. It's also used between mail servers. Receiving is done with IMAP or POP3 if you're on a 90s retro trip.
i still use pop, maybe that makes me retro but i think the fact i still use a seperate email client as opposed to a web based dealio makes me far more passé than any protocol ever could.
Tom Johnston Nah, I hate web-based dealios. OTOH, POP3 is just impractical as soon as you're using more than one machine to check your mails.
***** Not really :)
That is why IMAP became a thing, that way it stays on the server and just syncs it to your email client.
Hello, would you like to hear a TCP joke?
Yes, I'd like to hear a TCP joke.
OK, I'll tell you a TCP joke.
OK, I'll hear a TCP joke.
Are you ready to hear a TCP joke?
Yes, I am ready to hear a TCP joke.
OK, I'm about to send the TCP joke. It will last 10 seconds, it has two characters, it does not have a setting, it ends with a punchline.
OK, I'm ready to hear the TCP joke that will last 10 seconds, has two characters, does not have a setting and will end with a punchline.
I'm sorry, your connection has timed out... ...Hello, would you like to hear a TCP joke?
Perfect!
I can tell you a TCP joke, but then I have to repeat it until you get it.
Could you do a UDP joke?
W B-H I could, but you might not get it.
UDP would be spam lol
We have been studying TCP/IP for two weeks in class now. You explained it better in 7 minutes than our tech book has taken 2 chapters to explain! Thank you for breaking it down into simple to understand English!
I agree. but is this channel still active
This video is outdated now, the new 5 layer model is preferred going forward.
How babies are made As Fast As Possible
haha
Fuck in da butt
Linus + Asian = efficient baby making production "line" lol :P
when mommy linus and daddy linus love each other very very much...
It's me, 2 minutes or less, guaranteed. Satisfaction..not guaranteed.
is "damn it Taran" becoming the "shut up Meg" of LTT?
Taran*
sorted it's fixed, until I forget and spell it wrong again
"damn it colton" is pretty popular on the wan show :P
too true lol
"Shut the fuck up, Donny!"
6minute video that explained TCP/IP and ports better than my classes in school that i pay thousands for. smh.
this vid is just a simplified version of tcp you need much more detailes than this
true
Same here 😹🤘
He's explaining only how the TCP/IP model works, ISO/OSI model is what you learn most of the time, like in cisco networking essentials, etc. Because the ISO/OSI model is more detailed.
I had to write an implementation of TCP for a networks class in college. Man, it may sound simple here, but when you get into the nitty gritty of actually making these systems work, it sure is complicated.
Daniel Meagher exactly!
Your explanations are so clear and I do not think the jokes break up the flow at all. You really keep my attention while I'm prepping for interviews and trying to identify any knowledge gaps. Thank you!!
Ok, I just stumbled upon this, I have seen thousands of youtube presentations and you are absolutely superlative! It was quick(a plus for my ADD), concise, relevant, fun (w/o being too goofy or silly) and seemless. Thank you very much, you have an outstanding talent I hope you continue posting.
This one is well done. I have dealt in detail with packet switching and the 7 layer model while in college, this was a good visual and simplified explanation. I know the point is to be quick but my only suggestion would be to include NAT also.
well that should go in 'routers as fast as possible' or 'IP addresses as fast as possible'
Thank you Linus, I just started the ccna certification course so this was very helpful.
awkward moment when internet is much more organized than your life
I wish this was around when I was learning TCP/IP... Thanks Linus, I can now point other lost souls to this video.
So revisiting old topics with new fancy graphics! I have been waiting for these.
Didnt understand this after a two hour lecture but my man linus explains it in 6 mins what a legend
Thanks for explaining things in a manner a non-computer person can understand. Well worth the watch.
Hi do you know any more resources information like this to learn computing because i’m kinda dumb at this
I spent so many hours by watching videos on TCP/IP but couldn't understand. At last, this 6 minutes video made me understood 100%....
Rabbit ears, those were the good old day.
How to fool a scammer as fast as possible
Just my humble opinion, but I think that jokes shouldn't bring the flow to a jarring halt. I appreciated the packet jokes, but they really broke the flow of the video.
agreed!
No, Linus is just a serial killer. Those aren't jokes.
those weren't jokes...
I too think the videos would be better without cheap unfunny jokes and stupid sounds and animations.
2:11 really broke the flow for me lol
Actually, low-numbered ports like http (tcp/80) and smtp (tcp/25) are _destination_ ports. They don't describe where things are coming from. For that we have _source_ ports, which tend to change from connection to connection.
I didn't expect Linus to be saving me in my Concepts of Parallel and Distributed Systems class lmao
Dude... Please tell me this whole thing was an ad. The way you tied that in at the end was ingenious.
I like how you summarize all the Vital information.... NICE
OMG!!! I feel like I could pass my Communications and Networking course with this video alone!! THANKS LINUS....
So seriously. Thank you for explaining that in that way. You're literally the only person I've seen break it down in a non text book way. Oh yeah, I just subscribed.
Amazing i love it, like finally i understand it.. yesterday i was crying because i can’t understand what tcp/ip protocol is and now i’m crying because it’s so easy!!
Really thank you!
learning this right now in my networking class, and I have to explain it. Thanks for the good video. Much better than the provided class material.
As somebody who needs to be able to learn and recite this entire process by tomorrow I've never felt so happy to see an advert finally appear to signify the end of the video
Thank you for this video. Right now I'm learning about IT and this video is waaaay more entertaining than what I'm used to seeing.
@Alex Green
Heyyy!
Any updates about you now that you would like to share?
Would love to hear!
Coming back to this after starting a Networking IT degree....man, I remember the Tunnelbear debacle a few years back.
I think the OSI model offers a more clear picture to beginners... All People Seem To Need Data Processing
Application layer 7 (allows for communication to programs)
Presentation layer 6 (formats)
Session layer 5 (NetBIOS)
Transport layer 4 (TCP / UDP) Segments
Network layer 3 (internet / IP) Packets
Data line layer 2 (LLC / MAC) Frames
Physical layer 1 (Cables) Bits
It shows you understand this far better than I do, can you hp me out in my beggingner level. ?
They should do a video on RFC specifications. The guidelines that allow different computers and hardware to interact with each other successfully.
the most comprehensive TCP/IP video I've seen yet!
Thank you a lot!
THE BEST EXPLANATION OF TCP/IP FOR BEGINNERS I USED THIS VIDEO TO TEACH MY STUDENTS THANKS BROTHER.
so cool to see this linus explaining,we were learning osi model like 5 months ago :)
if only this video was released before my computer science exam. :'D
sometimes linus techquickie is explaining things better and easier then my teachers at school. (i live in germany and do a vocational training in IT)
Linus really has improved his delivery since back then.
OMG Linus, we need more videos like these. It's so helpful as I've got sem exam Tomorrow 😂😂❤
I'm studying for my A+, and this helped quite a bit. Thanks!
Thank you a a lot . that was really educational . I finally got concept behind . using simple and layer to layer description really helped .
Excellent informative video. Like so many of the others your have made. Brilliant. Keep up the good work. Cheers Man.
i like this a lot. it was funny,easy to understand, and quick. wish all instructional videos were like this one.
Every colleges and universities should incoperate these videos into their lectures
I couldn't think of a better way of explaining tcp/ip
Do more videos about TCP Layers and switching!
I think you've just saved my computer science exam. Thank you!!!
Something for learn everyday :)
Techquickie is just the best!
Linus to the top!!!
omg i remember this lesson from my cisco networking academy class i took in highschool!! this brought me back to them good old days. gosh i miss high school, but better booty in college ;)
Awesome!! I have never had so much fun learning before.
You guys do a great job with informative tech-things!!! Just Subscribed. Thank you.
So this school year we were studying these layers. And I've just learned more in a 5 minute video than in a whole fkn year. THX SCHOOL
yeeh me too
This was perfect for me.. This video worked great with my learning style.
Dude, I had learn so much about this in CCNA 1 haha, also had to do OSI layer.
Thanks to Cisco subject I took in high school, i've already known this. Good video for a refresh though :)
2:38 - Rx480 overclock on stock cooler linus
Hints .............
the 1.5 ghz on stock cooler meme actually made me laugh out loud
The little under your breathe "Damn it Taran" seemed so legit, thought you were legitimately just tired of him for a second there.
small correction: What in the video is called "internet layer" is actually the network layer, while the network layer described in the video is the data link layer.
Just used this to recap for my GCSE Computing exam tomorrow since I actually like Linus as oppose to any other educational channels. :)
Great explanation ! Made sense, keep up the great content!
Yo, he's definitely the go to guy. too bad this is from 2016. But I appreciate all the good info.
Linus can explain concepts in less than 8 minutes while my professor explain half of it in 90 minutes
I think I can sit for CCNA already by this LOL Linus could really be a good lecturer imo
Great Explanation man, and the punches though :D
super good, need more in-depth follow-up on tcp/ip
Very informative and thank you for the funny jokes in the middle! To all my emanagement students, I wish you the best of luck on Quiz #1! :D
Thank you for making this easier to understand you are appreciated
Thank you very much for your video! Really clear and helpful!
I keep coming back to these
thnx linus passed my exams with this simple explanation
Good stuff, as always!! keep up the good work :)
this is one of those 5 min video explains things better than a 50 min lecture
for receiving email IMAP/POP3 - SMTP for sending and transport ... TCP has not bigger latency but ... it is not designed to use packets on top of it (OpenVPN TCPvsUDP) ... HTTP only uses port 80 by default (hxxp://:) ... error checking is also in UDP (also protocols in 2 Layer) ... TCP only provides nice stream capability (like data connection in FTP) and API of BSD sockets (used also in windows) are very similar to file operations (recv/send family for UDP packets, for TCP read/write can be used)
Thanks for the video
It was really helpful
you are the saver of a CS student mate... well done...
Awesome explanation. Thanks!
thank you, this video cleared things up quite a lot
i like this easy way to understand the TCP/IP stack but you should have noted the existence of the OSI model
that RX 480 ... 1.5 GHz Overclocking reference ;) well played Linus, well played
You are the best man saved some time during exam period
what the ffff! linus actually helped in my studies! this was useful in my education!
linus of all people
HTTP doesn't have to use port 80, for example port 8080 isn't that rare and you could set it to be even something like port 1337
Number of Ports are 65,535 ports, from 1-1023 are known as Reserved ports which means they are reserved for certain apps or programs and cannot be used as a normal communication ports, from 1024-65,535 are known as Unreserved ports, and you can use for your end devices. Now for e.g., port 80 is only for HTTP, 443 is for HTTPS (Secure browser), FTP uses port 20/21, SMTP uses 25 , telnet 23 so on and so forth. Assume that you have many devices in your home network, and you want to prevent some users from browsing the internet, all you have to do is go to the firewall in your PC or Access point (router) and assign a port for your PC, let us say port 1025 ,followed by the mac address of the device, then choose Deny access to port 80, which is HTTP.
It is the most clear explanation that I heard.
Thank you! It was very clear!
Lol. Got me at the chops it off in little chunks and dispose in lake part.
watched the other videos on tcp/ip model but i cant understand their explanation well, com across this, understand in one time watch. thanks!
Set top boxes/TV tuners explained? It would be particularly relevant with the big US FCC debates going on around them.
TCP/IP are like onions. Onions have layers, TCP/IP has layers. You get it, they both have layers
Thank you for the video it helpd in my exam a lot.
cant wait to comment before I run this video over, amazing work! especially the sandwich part!
is that meme a RX480 reference
100% 😂
most definitely
Hidden leak to avoid breaking NDA, I think.
Could also be he's just using it as an example of a recent meme (where the soon-to-be-released RX 480 was rumored to hit 1.5GHz overclocked by a source that seems to be churning out all sorts of controversial claims), and it doesn't actually mean anything. This video was probably made pretty quickly, and whoever procured the image probably had that on his/her mind and used it as a relevant joke/reference/shot. That's my guess, at least.
+Moop Entirely possible
good and clear explanation, great vid thanks :)
Great video and explanation! Thank you
from the core of my heart
thank u
video editing and points was amazing..
The more I watch him, the higher his voice gets I swear...
Jokes aside, a brilliant video, highly useful for my A levels!
