REPUBLISH... I keep getting dyslexic on bits and bytes...
Online classes?
Hi Eli, is there any major difference?
I already watched the "previous one", may i ask where is the edited part of it?
Thanks!
... it's about 3 seconds worth of dubbing over... I just said 8 bytes in a bit, so I did a janky redub of the few seconds and reuploaded...
@@elithecomputerguy Great, thanks!
Your old Networking Course is still a goldmine to this day, but it would be amazing if you could have an updated version of it :)
Hi Eli,
Your technologies related videos/coaching have been really helpful to understand things from scratch. Please keep making these videos for our learning.
He's got a LOT of videos over the years, it's good to see him back now.
Man, this is pure gold. Your real world examples make everything so much clearer!
Please, please continue this series. You're literally the first educator I ever came across in UA-cam and your networking series still remains absolutely amazing.
How is he so succinct and articulate. Speaks and explains with so much clarity and thoughtfulness. Omg.
Could you create series of networking classes? Maybe some labs, best practices? I guess everyone is missing your tech courses
don't forget to specify ip4/ip6 😂
Thank you for these lessons you've been uploading. been in IT for 8 years now and it's nice to go over these topics to reinforce a solid foundation of knowledge
My kids are 9 and 12 and they have known of OSPF since they were babies. I try to teach them to apply OSPF to everything in life to be more efficient.
After 15 years as a software jockey and another 15 years as an IT janitor, I can say being a florist might have been a better idea. Joking aside, I'm glad to see you making IT content like this again.
Agreed.
Thank you for bringing back your classes. You are awesome!
My head is still spinning - Bits per second discovery was a bummer! Real gold class videos!! Thanks a ton mate. Super helpful with summary at the end. It helped with a quick recap and thought recollection.
The best network course ever.
All ways liked your classes Eli straight forward and to the point.
Thank you for all of the hard work you put into your tutorials. Very helpful, informative and easy to follow. Still find myself referring to them from time to time.
It's a one-hour class, but you covered as much as other classes do in 10 hours. I appreciate your effort.
Eli keep up with this series please. I’m a web developer , but find this stuff exciting.
Thought I would only watch a few mins… ended up watching the whole thing. Lol.😂 Thank you for your take on what a computer network is. Lots gain from this single video. Can’t wait to watch more.
Thanks! Awesome videos I am glad that you are getting back videos
Very good vid Mr. Eli. Thanks for your hard work, making these informative vids, for us to learn.👍
Awesome! The technical videos are back! Thanks so much!
I've been waiting for you to do some more tech videos. Good to see you back🤓😎
I really love people like you. Thank you
Mostly commenting for the algorithm.
Great video. I'm currently trying to start an IT career and find your content very helpful.
Eli, welcome back 😊 as a teacher my self, I'd never talk about a cluster and network in the same network sentence😬😉
Extraordinarily accomplished. You explain the topic in a very easily understandable way.
I was getting rusty with networking. Thanks for rebooting these informational videos! 👍👍👍
HE IS BAAACKKK!!
Quite nostalgic tbh, happy to see you teaching long format again))
Hi Eli, in beginning I would like to thank you for the huge effort and energy that you have been putting for many years now to teach people like us, with free education more importantly qualitative teaching as there are very few people who could have pedagogical methods like you do.
I see that on September you are opening new courses in Silicon Dojo, I want to ask will those lessons be in your UA-cam channel and follow you from there, as actually I live very far from US.
Big thank you, you are changing many people lives.
Old Eli is back!
I'm totally stoked!😲
I like your vidoes and your explanation so much.
Keep up the good work, Eli.
Hi Eli. Thank you so much for the great video. I will be listening to the series. However, I took my EE degree in 1980, so it pains me to have the old network topologies disrespected so much. Many may be obsolete in their original incarnation, but the concept and theory should be studied as they frequently come back in new forms. I2C which you brought up, is a buss topology. All the networks around us like CAN Bus , cell networks, mqtt networks, etc.. may use old concepts in a new way. Imagine what the deep space network will be in 50 years. Thanks again!
what an amazing video! i found so much value from this, thank you !
With all those frameworks, languages to learn. I put my wishes to learn those on the shelf and putting time to learn the fundamentals and omg. You are one of the best sirrrrr ❤️❤️❤️❤️❤️❤️
many thanks and more of this valuable lessons please
Love your content Eli it's flipping rad dude! Thanks again IT Sensei!!!
About the data transmission via light, there were certain things where it used to be possible to read the raw data on a hard drive just by having a sensor or camera or something pointed at the hard drive light or networking light or some such on certain old things
I feel like a good extreme example to demonstrate the difference between speed and latency is imagine you have a storage drive (could be a flash drive or hard drive or SSD or SD/microSD card, whatever) and it's already full and you grab it and put your shoes on and drive it somewhere and plug it in to a computer somewhere.
You might have an amazing effective speed transfer that way, but the latency is howeverlong it took you to drive there, which is not anywhere near acceptable if you were expecting it to be the same as having a wired or wireless or even satellite internet connection.
This is an extreme example to demonstrate the difference between speed and latency, and why they matter.
You expect a snail mail letter to take at least a significant portion of a business day to get somewhere, but you would be confused if an internet connection had more than a few seconds of latency.
Expecting sneakernet to have latency anywhere near comparable to an internet connection is similarly silly, but it demonstrates the difference between speed and latency.
Awesome stuff. Thankyou.
The little Morph on your shelf is a wicked nostalgia kick
🙂 Thank you, really enjoyed the video
I bet someone maybe is working with Orb-Fi on a secret lab. Thanks for posting !! excelent videos.
Nice beginner class.
Thank you Eli !!
Thank you Sir. Eager to learn more.
It is a communication connection between 2 or more computers that allows for the flow of data without the need for external storage. You can start with a Null Modem.
Awesome Eli
Eli, my attention span is growing shorter as I age but thank you for reminding me of what I learned before my health went south.
Getting my floral professional certificate soon!
I did low volt communication wire laying before. A lot of drop ceilings and throwing jet line through it.
For the token ring, when it receives a request from a computer, and it's following the loop to send a message to another computer, can it be stopped while enroute by another computer, and given a message to deliver?
GOD bless you !!
Hi Eli,
you teaching style is priceless. We don't have many of such teachers as you are. Do you have a course on Udemy, or youTube, or anywhere, like this one here, which could enable us to qualify for an IT JOB such as System Administration or Networking specialist, or Cyber Security. I mean this is all theory on your channel, which I find amazing and priceless the way you teach. Do you also have some practical exercises, projects and assignments/Challenges, which would actually give students the experience they require to land an IT Job?
Thanks and kind regards,
Armaghan
Hey Eli, just wanted to say thanks for all your helpful videos! I hope we can meet up sometime, that would be awesome! 😊
Lookup Silicon Dojo, That's his in person classes
Thanks
Will you have online classes
after recent videos , i forget how good you are as a teacher, when you solely focus on teaching. 😂😁
Sir we need vendor specific courses like CEH, CCNA, AWS. Willing to buy any of your course
Agreed. I dropped 30 on a ccna udemy course. I'd drop double for yours
@@rhrabar0004 Seems for me none of you are watching Eli Channel on a regular basis. :)
Toilet paper roll ccna ._.
where will i learn storage , compute, storage
If my email is in the cloud then how can I still access it on a clear day? 🤯
Would you be cool with sending you some questions and you making a video on those topics? If you think it would make sense to make a video on those topics in the question of course.
it's nice to see you do what you do best, and that's teach. Not how vaccines are saving people.
Is it 2015 again? I let my A+ cert lapse last year.
מלך
I heard the internet is a series of tubes, confirm/deny?
You Tubes, perhaps.
Eli.. making Grandpastuff great again.
im still confused about latency vs speed
God bless 🦀
Underground facility 😄
Maybe the first sound was the sound of Eating that's the last packet of information I received
It's actually funny he has declared he is doing this to kill the channel because people will not watch him talk about something other than gossips and whatnot.
That’s how Eli the Computer Guy entices people to his political videos :D)))
"IPv4 is going to be dead in 5 years tops. Mass IPv6 adoption is just around the corner"
- somebody somewhere 20 years ago who already died 10 years after uttering that statemen
🥰
Now you back to talking about computers instead of politics
There is no difference.
What is this "COMPUTER", you speak of?
It's a series of beads which slide on rods arranged in a square wooden frame for the purpose of computing numbers together.
HAL9000 the next President after Elon get's drafted.
Sadly, I see vampires taps daily.
You misspelled "Who is Elon Musk? " in the title
Where's the RARRRRR videos???
You are watching one. Eli has hope again and isn't rarrrrring against the machine as much. Enjoy the white pill.
Over an hour in and nothing about bezels 😑
Wtf it's not called introduction to networks??? You have changed for the worse eli

>he says bits and bytes are confusing
wait til you try to keep straight the difference between gigabytes and gibibytes, megabytes and mebibytes, and kilobytes and kibibytes.
Oh god, please don't tell me gibibits mebibits and kibibits exist
Edit: oh god, they do
