This video is part 12 of an intro to networking tutorial: • Networking tutorial
Ben, you are an incredibly gifted teacher. You not only have an amazing grasp on the concepts yourself, but can easily explain them to someone with little to no domain knowledge. That takes serious abilities to recognize the concepts that merit more depth and explanation while not getting hung up on the minutiae. All your videos are just incredible. Sincerely, thank you for taking the time and effort making these videos for strangers on the internet.
- a stranger on the internet.
First of all I would like to thank you for creating these videos and for your efforts.
This series help of lot of people around the world including me. You have explained thing very well, it really helped us in getting the better understanding of technology.
Please keep doing this good work.
I want to echo everyone's praise on here! These videos are masterfully done and have given me knowledge I don't know where else I would get! Thank you so much!
This is great video series. I enjoyed every single one of them and learned a lot. Thank you for sharing knowledge.
Really well explained videos! Learning this in college at the moment and this explanation is just a million times better than my notes!
My friend, I have been looking for this all these years. I can't thank you enough.
Flawless explanation. Thank you sir!
TCP/IP goes global (1980s) I remember during nights in college we were connecting into Microsoft Seattle after Arizona fall . You downloading all night software .
Right before the end dirty phone lines drop ! Wow ! Starting from scratch . So we start developing Z-modem protocol ..Posted code on bulletin boards.
That was the change we needed TCP /IP .. AK.. Microsoft -Novell developer Utah Cut,inc bulletin board around 20 thousands register users... Year 1991..
TCP is the phone call. IP is the conversation. That makes so much sense now.
Cool little video that presents the problems that TCP program solves.
I like this style of teaching.
Intuitive and lovely.
Thank You Sir!
Thanks Ben, you really save my life from the exam
Ben, addicted to your knowledge sharing videos.. However unfortunately I couldn't find the full series of videos.
This playlist is awesome. Thank you so much!
Amazing series. Hope you can keep doing more videos because they are very useful for education. Many thanks!
Best networking course.
BEST lecture EVER !!!!
thank you for even making these videos
Your tutorials ended without explanation how TCP do this four tasks. Didnt find yet such good explanation of this as yours
people think internet is all about your download speeds when its not its all about transmission control protocol and the infrastructure
Firstly, thank you for the amazingly in-depth series. I am, however, a little confused insofar as it is my understanding that private IP addresses are non-routable on the internet. Yet, you show packets with private IPs in the source and destination fields. I don't understand how this would be possible since many hosts could have identical private IPs on different LANs. I am familiar with the concept of NAT and NAPT but it seems that those protocols aren't being used here. I am confused as to how the routers "know" which LAN to send the packets to.
Isn't flow control when you deal with computer B not being able to handle data at the rate it is receiving?
Your indeed right sir :)
It prevents a fast sender from overwhelming a slow receiver.
That said, awesome and clear video!
Telling apart "multiple conversations" (demultiplexing) is *by far* the easiest of these problems to solve. Even UDP can do it (it's the only thing it does over IP).
Thank you for excellent videoseries on Networking!
I have a question on the ACK-number in this example, should it really be "23" ?
Best Regards.
Ack number , is the sequence number of last packet the receiver received, so if we send 100 bytes , so the sequence number is 100, so the sender should receive packet with acknowledgement number set to 100 , if not it will resend the associated packet again
Amazing video Ben. You explain concepts very well, u got a new subscriber :
Danke!
These are so beautiful can you put the stuff u usually read from
I like the elegance of all of this. But it seems very wasteful. 1500 bytes is not a whole lot. For every 1500 bytes you have to resend all the Ethernet, IP and TCP headers. For directly connected computers, you can of course just talk in raw Ethernet, but for the larger internet, are there protocols that are more light-weight?
Yes - look up UDP. Basically rather than using connections to ensure that data gets transferred correctly like in TCP, UDP has no connections and doesn't attempt any error recovery or reordering. It's commonly used for things like video games, live streams etc - when speed is important and dropping a few packets isn't.
I got a question if any one got an answer, we agree that technically information are are passed with a bunches of 0 and 1 through 5V then 0V or with manchester code ? (correct me if i'm wrong) so imagine all 6 computers in NYC and SFO are playing some online FPS games which servers are in Denver (I dont know if it works like that but), I wanna know how all information are separately passed at the same time without getting superposed, i mean all 6 computers send something to Denver at the same time right ?
Thank you!
you are a life saver ben
Best explanation i seen
Great job! Thank you
Best explanation ever!!!
Thank u for ur videos
Ty Very much
Is there an acknowledgement sent for each packet?
All networking videos are very good ! Only one complain: why would you write you on the fly, which unnecessarily wastes viewer's time. (I had to go with 1.5X). Hand writing is very difficult to read, too.
any videos coming these years, Please include TCP congestion control and retransmission
What about WiFi protocol , is it eventually converted to ethernet frame ?!
Yes
great , great , great ........job
thanks alot
100000000 like
Excellant..!

Dear Sir, I have watched almost every of your videos. I kindly request you to build a series on internet connection on the custom hardware like the 8 bit computer or the 6502 computer. I am currently building a 32 bit computer with vga output and a usb keyboard, mouse input. I am also planing to build an OS for it. From your kind subscriber. Thank you for your kind support.

You are confusing congestion controll and flow controll
wrg, no such thing like that or have or not. talk/convx/can talk/can convx anyx nmw and it can all be perfx
Thank you!
