To all the "perfect" guys that comment here about the mistake on the board (1 bit = 8 bytes) let me break it down to you. If you've watched the video and listened to it carefully you'll hear that he actually says 1 byte = 8 bits, he just made a mistake while writing it, which it can happen to anybody. Also if you've read the description bar you would have noticed that the mistake was pointed out and it has been corrected. So out of 1 hour lecture he makes a single mistake, which he actually corrects it and you just complain about it instead of thanking this man for the knowledge that he shares with us FOR FREE!
he made a serious mistake apart from the bit/byte thing that anyone can make.....he does not know what sychronous and asychronous is....which is a thing than you learn in the first class of any computer science/networking/telecomunications course....
Eli the Great! thank you. You're true,genuine and real SMART guy because you share your knowledge. Real Smart person shares knowledge and explains in a very comprehensive way.

oh man, you need to do a time lapse montage kind of thing from the beginning to now. You have been and continue to be an inspiration and instructor to so many.
Dear Eli Your videos are great. I really like your videos. I am a teacher but I have a knack for IT and related technologies. I usually like watching videos on IT and improve my knowledge. I have watched many of your videos and I know a lot. Tonight. I am studying proxy servers and broadband technologies. I downloaded the two videos. Great work. Keep sharing your knowledge. People benefit from your work. I truly appreciate your hard work and knowledge you have. Many people do not have good knowledge. You are an expert. Keep good work. Upload many videos, please. I learnt many things by watching your nice videos. Hats off to you, Eli.
Had no problem or issue with the basics; the courses I'm doing cover the techinical stuff, too. What makes your vids so informative is the honest consumer critique and the insights this offers to real world IT and the condition, human or otherwise of the environment out there. Failed normal?!? you gotta laugh! Cheers!
Eli, I must say you were a born teacher. With the knowledge and personality you broke it down exactly like it should. I work at a NOC and I need to brush up on things constantly to reinforce my skills. It always is great to hear a "personal spin" on a technical course. It is refreshing and fun.
Thanks Eli. I am pursuing a degree in Information Technology and your videos are assisting me in achieving that goal. When I first started I went on the internet looking for additional knowledge, which i thought your videos provided!
+Jonas Paskus You're saying that 100% of what he described was incorrect for the time of video upload? Perhaps you can publish a video that's 100% correct? Please enlighten us.
THANK YOU FOR THIS AWSOME CLASSES YOU'RE AN AMAZING GUY, ELI THE COMPUTER GUY, THANKS A LOT, THIS IS AMAZING I WISH YOU COULD MAKE MORE TUTORIALS ON EVERYTHING ABOUT COMPUTERS, I'M SURE THIS CHANNEL WILL GET MILLIONS OF SUBS.
Thanks for these awesome videos! I wish they were more up to date, because I'm noticing that a lot has happened over the last 6 years (wireless ac for example), but these are amazing. Thanks a ton!
thanks to you, I finally found a way to study while I'm halfway asleep - huge amount of useful information and I like the format of you just ranting about your topics in one fluent talk. It's ideal to listen to while gaming or having a powernap. you should consider making soundcloud podcasts! there would be many guys waiting for you! keep up that good work! best wishes from Germany
No problem here. I think that he did a great job. the bit/byte mistake stuff doesn't mean a thing. I knew what he meant. I am grateful for the content. Great job!
Eli, you are definitely the man (or "guy" :P ). Thanks for the great tutorials and lessons on this stuff. Its always been an interest of mine and you make the material real accessible and easy to understand. Your contribution to learners is awesome. Cheers!
Excellent video. Very informative. I've spent the last 7 years doing civil permitting for FIOS projects. 2017-2018 is the big push by these telecom giants. Billions. They are want to push fiber to individual homes. You'll get a mini node in your house, and the speeds will be insane to put it mildly. Exciting times ahead.
"Correction: 8 Bits = 1 Byte -- In the overview Eli had a dyslexic moment and switched it." I just love this. :D I watch and laugh so hard, saying one thing, writing other :D I know that problem dude. U rock!
hey..you're a gem..i always go through your videos whenever i get time.. for this video 19:53 the funniest moment..really.. thanks a lot for sharing all the talent you have..
Hi Eli, I was a little confused about the difference between bit and bytes as I learned about that some times ago in college, great you made correction. Anyway great vids, I love it. Keep it up!
If Verizon (56:18) didn't force you to use their crappy equipment and just gave you an ethernet jack at their ONT that I could run a CAT 7 cable from to my router, I'd jump on it in a nanosecond! But for now, I'm load balancing TWC and Comcast into my router to get decent speeds and 99.99999...% reliability. P.S. I love your tutorial videos, Eli. I realize the older ones are a bit dated, as people in the comments below are complaining about, but you've uploaded a great many videos over the years and I can understand that keeping them all up-to-date would be nigh impossible. So cheers! :-)
8 bits/bytes... he was partially subconsciously correct... he didn't visually and auditorally integrate his subconscious when he physical wrote it. But still amazing in his delivery of challenging data.
i just dont know how to thank u man !! f**k all my lecturers :P i swear i dont attend their classes, all i have to do is to go to ur channel and browse it, and am 100% sure that i will find it :) u helped me through my career, and my studying :) again and again,, thanks a lot.. best of luck buddy :)
In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream. Any timing required to recover data from thecommunication symbols is encoded within the symbols.
because lazy people just want to learn everything in one 5 minute videos great quality stuff like Eli channel takes a lot more then 5 minutes cus there's so much to teach and a high quality standard! BTW thanks for your Hard work Eli!!!
(15:25) About ISP's blocking certain Ports, can they block the port as a transmitter (SERVER) but not as a receiver (CLIENT)? Or are ports block bidirectionally (i.e. when a port is blocked it means that no data related to that port can be transmitted or received)? For instance, lets say I want to run a WEB-SEVER from my residence: Can the ISP block data-transmission TO Port 80, so that I cannot provide the service, and at the same time NOT block data-receive FROM Port 80, so that I am allowed to access youtube WEB-PAGE? Or once the ISP blocks Port 80, I can neither provide my WEB-SERVER nor access TH-cam?
I think symmetrical and asymmetrical are the terms used for upload and download of data ... If upload speed equals download speed - the network is symmetrical... if they are at different speeds; they are asymmetrical. Synchronous and asynchronous has to do with clock speed and data rates --- Asynchronous Transport Mode for example means that data is loading at different rates... with varying time frequencies, while Synchronous Optical Network happens 8,000 times p/second synchronized.
Hi Eli, Any chance you could do a more up to date one which goes into differences between the dsl family, love your videos been watching your videos for years, helped me pass my CCNA R&S, Security and half way through my MCSA server 2012R2
Thanks you so much ELI for sharing your knowledge !!! You way of explanation is flawless which makes me your big fan.....I want to have a word with you ......howz it possible..?

Although this video is 6 years old the information is still quite relevant. I'm using it to supplement and drill in what I learn in class.
You are a great teacher , at 2024 and your teachings are just superb.
Thank you sir.

i have to say the detail you cover topics/subjects...... absolutely the best. with excitement too. awesome.
I really enjoy your videos , old classes like this one or new content - used to be daily shows , now once in a while.
Keep it coming.
Bless you Eli. All your videos are still great today!
8 bits = 1 Byte 4:03
That's his correction, everybody could make mistake, Eli is the Man!
Very much appreciate the level of organization both on the video and in the video description.
Hey Eli, thanks for all the effort you've put into these videos, I really appreciate it.
Thanks Eli. I am pursuing a degree in Information Technology and your videos are assisting me in achieving that goal. When I first started I went on the internet looking for additional knowledge, which i thought your videos provided!
One knows their trade when they can teach it so well. Great job!!

I like your videos man. You are literally my teacher. Even though 1 byte = 8 bits.
Excellent video. Cleared up in an hour what would have cost me $1500 a semester.
No problem here. I think that he did a great job. the bit/byte mistake stuff doesn't mean a thing. I knew what he meant. I am grateful for the content. Great job!

It's hilarious how much internet speeds have increased since Eli made this video. 50 Mbps and 100 Mbps were considered top-tier high speed lol
You have a very good teaching skills Eli! I wish my teachers were as talented and skilled as you are. Thank you for your hard work.
"Correction: 8 Bits = 1 Byte -- In the overview Eli had a dyslexic moment and switched it."
I just love this. :D I watch and laugh so hard, saying one thing, writing other :D I know that problem dude. U rock!
You are the best one i ever seen, keep on posting videos so that you help people and GOD may bless you!
Thanks for being awesome Eli! :)
Hey Eli, I just want to say, Thanks for teaching us dude.
They are getting paid by sponsors, but his classes are great indeed. Keep up the good work Eli!
These Video Tutorial Series. Your Teaching Style. Awesome And Cool. Thanks for all of the videos.
Eli my teacher i learn a lot from your videos thank so much
hey..you're a gem..i always go through your videos whenever i get time..
for this video 19:53 the funniest moment..really..
thanks a lot for sharing all the talent you have..
You are the boss!! I do not have many friends in the industry so its pretty hard to come across advice and information. Thanks!
You are so great. Thank you so much for taking your time and offering us these wonderful videos. Thank you so much! :D
u have the look of a construction or contractor with the intel of a well u, a good teacher
Awesome class! Love this guy's passion. I've been takin notes on his lessons.
Love the opening intro to this video;)
Hi Eli,
I was a little confused about the difference between bit and bytes as I learned about that some times ago in college, great you made correction.
Anyway great vids, I love it. Keep it up!
Thank you very much for broadcasting this astonishing video really enjoyed. Cheers

@shawnofdenver you are correct...
Eli the smart and intelligent Guy ... thanks a lot :)
what an explanation sir! i love your all videos lots
8 bits/bytes... he was partially subconsciously correct... he didn't visually and auditorally integrate his subconscious when he physical wrote it. But still amazing in his delivery of challenging data.
Great videos a lot of help while I'm working towards my degree. Thanks a lot!
A lot of USEFUL Information ! Thank you !
thank you so much Mr. ELY i like all your videos a genius man in term of info.tech. keep up the good lectures...
Kudos Sirji, ur my network guru - very impressive.
He wrote the wrong definition on the board, but verbally said the correct definition. It happens to the best of us ;)
An excellent video covers the topic very well!
Thanks.
Great information, how ever, watching this several years later 15Mb connection, I chuckled. I average 115Mb connection.
Yay, he showed the correction! I love Eli :0
39 : 47 ... Oh! Damn It Started Recording ;) .... Eli .. Your Videos Are Not Only Very Interesting And Educational But Its Fun Too...You Rock Man !!!!
Started taking classes. Keep it up. great stuff.
Thank you supreme computer guy
i just dont know how to thank u man !! f**k all my lecturers :P i swear i dont attend their classes, all i have to do is to go to ur channel and browse it, and am 100% sure that i will find it :) u helped me through my career, and my studying :) again and again,, thanks a lot.. best of luck buddy :)
Hi there Eli
WOW, wonderful computer networking videos; thank you so much!!!
In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream. Any timing required to recover data from thecommunication symbols is encoded within the symbols.
Thanks Eli, this is really helpful to me, I want to become an IT pro, please help me on what I can do more. Keep it up Eli, Thank you.
I really like your classes, thank you for making them!
because lazy people just want to learn everything in one 5 minute videos great quality stuff like Eli channel takes a lot more then 5 minutes cus there's so much to teach and a high quality standard! BTW thanks for your Hard work Eli!!!
Thanks for your help Eli
I understand you perfectly professor !
Very detailed lessons. Thank you.
You're the best Eli. Thanks for the videos.

aboyapart port blocking goes both ways
thanks.
Eli you are great...Thank you!
excellent video. Can you do more video about limited data internet and how to choose the internet plan
Thank you for the correction Eli!
good one. I wish it is up to date but still very informative

you are doing a remarkable job ! thank you very much :) awsome Eli the computer guy :)
thanks so much the interested guy,i hope you will post some ccna guide videos
8 bits = 1 byte Thant's the way I've been taught anyway. No big deal but remember that some people think of it this way instead.
***** no .125 is 1/8th
he did the correction check the description
I know, already wrote the post though.
Eli Thanks for share your kwnoledge with us
Loved it !! .... It really cleared things up for me , Thanks eli :D
These videos are great. Have you tried grinding out the CCENT/CCNA material with only books? Brutal!
Thanks Eli
Great information thanks for sharing.
Thanks for the information bro keep up the videos I'm learning a lot but just want to confirm about the bits and bytes
fantastic !!!!1 keep it up sir....
i dont know some one noticed but you wrote 1bit = 8Bytes, however this is other way around :)
should be 8bits=1Byte
+Muhammad Rafi A little brain confusion as later in the video he says it right. That kind of mix-up happens all the time.
this little brain confusion could make bigger brain confusion for starter unlike you a master :)
Muhammad Rafi I wondered that as well
Yeah I was like.... hold on.
yeah i check the first wideo about network that hi did and hi says it right 8 bits = 1byte
Hi Eli, Any chance you could do a more up to date one which goes into differences between the dsl family, love your videos been watching your videos for years, helped me pass my CCNA R&S, Security and half way through my MCSA server 2012R2
Thanks you so much ELI for sharing your knowledge !!! You way of explanation is flawless which makes me your big fan.....I want to have a word with you ......howz it possible..?
great guy great video - thanks
Great video! Thank you so much!!
I HAVE CABLE INTERNET AT MY PLACE.I GOT NO MODEM.WHAT WUD U DEFINE IT BY?
Yep! u was right 1 bit = 8 bytes ... its really .... really hardest thing to digest :P :)
whats the best way to attack the network+ exam?
You the man eli!
