If it's hard, it means we are progressing! Keep it up fam
Thank you :)
good analogy
Did you get your CCNA brother?
What I like about your method of explaining is the occasional use of comparisons and reference to past lessons. This helps me connect the entire course together in my head and also to develop a point of view and not only just remember facts. Thanks again!
Thanks, glad to hear that :)
🤯 🤕 Too much information, other instructors will put me to sleep, but your videos keep me excited and motivated to learn. I can even watch your videos several times. :)
Indeed there is a lot of information to remember! Glad my videos are helping you :)
he is professional in this area
@Studio S.S Do not try to remember everything like this, write notes, I use dropbox paper and it really helps!
Facts
Yes that's a lot of information!! The flashcards are really good but there are also too many of them! 56 just for this lesson is too much i think 🤕🥴
I have never seen content like this relating to CCNA or network fundaments. Seriously I appreciate you sir with all my heart.
this is the first video in this course that i didnt understand it well its very complicated for me :( i hope its not very important in the exam
I recommend watching it again and trying to learn it. This is probably more detail than you need to know for the exam, but at least be familiar with the purpose of each section of the IPv4 header.
true i agree too. it's a bit complicated i assume .
but thanks jeremy keep posting. we will understand at one point
@@JeremysITLab Do you think it’s important to memorize cabling distances and ip header byte information?
I was about to post a comment ''is this video complicated for everyone or just me?'', and I saw your comment first :) so it seems that it is complicated for most of us.
Man, this is a lot of information. I really have to attack the flash cards. I get the basic concept but its a lot of material to remember for a header. Thanks for the flashcards and the visuals. It will aid a lot in studying this material. I may have to watch it a few times and study this deck separate from my combined deck until I nail it.
Did you pass the exam? Is it necessary for the exam?
Man... this part rough , thanks all the works you've done for us .
when I get a job inshallah , I will send you on paypal ..
you are the reason why I love network now
thank u so much for the effort , please dont stop
Thank you so much, I'm glad you love networking!
your explanation is very clear jeremy. I just could say thank you for all these incredible lesson you've delivered
Your walk throughs are always so helpful. I had struggled to find any class that as in depth as I need but now i feel confident I can pass my CCNA!
It is simply amazing how you make complicated content so simple. Thanks so much Jeremy.
Thanks Joyce :)
Hello my fello Kenyan🤝🤝
This is a most fantastic course! I have ordered the ENCOR course from your site as well! I have also taken the CCNA gold boot camp course. It is well thought out and structured but I find the presentation that you offer and your style of teaching to be far superior. Merci Jeremy!
Came here on Keith Barker's reccomendation ( CBT nuggets) and i am not dissapointed. Some of the best learning on youtube. Thank you
I appreciate how you split up the information into multiple videos! Makes it a lot easier.
Thank you for this amazing series. This is saving me tons of money and time. Thanks to you I can utilize this quarantine time to me benefit!
Thank you, I'm glad you're using the time well ;)
You know what, I can't help myself to stop watching your videos specially on weekend because once I started one video I need to continue until I fell sleep or need to eat to pee! :D thank you so much Jeremy for such a wonderful and amazing videos, flashcards, and labs... one of the best channel I should say.
Thanks Jeremy for your amazing videos! I started taking some Udemy courses on CCNA and your way of presenting the information is so much easier to follow. I find it helpful that you provided anky flashcards and lab sections.
Truly best explanation ever. I have covered 17 videos and I have promised myself to complete all the videos after watching this one. Thanks sir.
I love the series so far. I am on day 13 and am looking forward to completing this course. Commenting this on every video for the algorithm.
Whew! That was a lot, but I retained more than I thought I would. Jeremy, I love you, bro.
Yeah there's a lot to remember...watch the video again if you have to.
Great job Jeremy, keep up the good work.
Hello Jeremy
I hope you are doing well,
Im Glad to find out in youtube a talented/professional person like you helping people to learn and grow up their knowledge, at this point of my life Im studying to become a Juniper Routing engineer, however I have my networking knowledge based with Cisco, im reviewing the networking basics back again and found your material and help me a lot to complete what im studying I hope I can have my certifications and keep studying learning so I can help others like you do, once again thank you for your support and help and God bless you!!!
I'm just Impressed how brilliantly do you explain hard stuffs. Thank you for your work!
Fantastic video, I loved that you made examples to demonstrate fragmentation and showed how to view it in wireshark.
Jeremy you have made the content so easy to understand. hats off for your incredible work. many many thanks
Well, so far so good. Your lessons are really right sized. As a software developer and having some knowledge of the domain, I'm progressing a little bit faster, but it's still really informative and I think, speed would not be the case after certain point. Anki cards are really useful piece.
Thanks for your effort to share invaluable knowledge and I will certainly thank you after course is passed.
It's great that someone published that kind of material and provides all other sources, it's really better than paid courses on well known platrofms i used to did. Thank you Jeremy
Thank you, Marcin :)
Thank you so much for these amazing videos. You do a great job of making things simple. This was a lot to chew, but you made it easy to understand. This is really helping me.
Cheers, I'm glad it helped!
Had to watch this two times, complete the anki flashcards and watch this video again. A lot of great information :D
Comforting to see that others found this to be a truck load of data.
This was an insane video but loved the learning! Onto my flash cards! Thanks Jeremy!
Yeah there's a lot of info in this one!
this is fairly the best thing ive ever found on youtube EVER. thank you!!
Glad you like it :)
Thank you for all of these videos Jeremy! And thank you for the flash cards, they really help to hammer in tons of information like the amount in this video.
Again, this video is so clear, so understable. Thank you so much :)
Thank you for all your comments :)
Compliments of the season J, Travel but now back and ready to roll. Thanks again for yet another bomb for more to come . Always grateful. Time to dive in
Welcome back Glenn!
The flashcards are what i missed in my days in school. I would have been a genius by now :). Thank you Jeremy.
Me too! I would have definitely gotten higher scores on my tests if I used flashcards in school!
you mean high school? you guys get network course in HS?? Which country is it?
@@George-mk7lp Flash cards can be used in any kind of studies. This has nothing to do with Cisco or networking. Flash cards is a studying tool.
@@BijouBakson oh sorry I thought u mean network related flashcards .. I just heard that there are networking classes in some US high schools..
@Jeremy You are the best Networking teacher!
Thanks! I had to watch all the videos for days 11 and 12 and then come back and rewatch this video before I could understand, but I do understand now.
Dang it, today i was sitting like 2h on the flashcards to memorize the information. So far Ethernet Header and IPv4 Header things ware the hardest to remember :D
Thanks Jeremy.
Your clear pronunciation is appreciated. It helps in understanding the context.
Thank you, I'm glad to hear that :)
Hi Jeremy!
I'm currently at Day 10 of your CCNA course, but I've found it much more effective to learn the theoretical and practical material from you than from the paid course. Unfortunately, I need to participate in the private school's course as well to be eligible for the regulatory exam, because I need the certificate to apply to the accredited exam center.
But, to say something positive, the two complement each other, and my instructor was surprised that I can apply what I learned from you in their course as well.
I'm studying to become a junior system administrator, and we are covering CCNA RS1 and RS2 as part of the curriculum
The wire shark part was a good idea. I’m finally able to understand those fields when using it
I must say, I am really enjoying those video classes much better than the online classes I have been attending. Gives me the Edge is grasping information. Many blessings & Thanks to you keep up the good work/videos.
Thank you! Glad you like the videos
Each router that a packet encounters decrements the value in the packet's TTL field by 1. So at each hop, the IPv4 header changes, and the router must recompute the value of the header checksum field. The Wikipedia article "Internet checksum" notes that there are quick ways to do this when that's the only change. (Presumably there's more overhead when packet fragmentation occurs.) IPv6 gets rid of layer-3 header checksums.
Incredible Information.
Thank you so much Jeremy!
You're the GOAT!! 🐐
Time could not erase the nature of your teaching in sharing us knowledge... You become a part of my IT career... Thanks a lot GOD BLESS...
Thanks for your comment, I'm happy to help :)
I forgot much of this stuff damn me! A revision always does the trick. Let's revise with the flashcard now! Thank you Jeremy.
Always important to review! With so much information to remember, it's easy to forget some of it.
@@JeremysITLab Yup!
Thanks for teaching us today's lpv4 header, so understandable
Thank you :)
Folks, I'd like to welcome you to Jeremy's IT Lab.

Great. THANKS! Very helpful!!!
Keep the great content coming!
Thanks for your support :)
Thank you so much for this series.
Thanks for watching :)
In quiz question 2, perhaps (c) is correct as well. If the minimum is 5, zero indicates some kind of issue.
Good explanation.
this course is so clean
Hello Jeremy, I will remember you when I get my job.
Thx Jeremy for the video
Day 10 in the box. Thanks m8.
Hey Jeremy. Your videos are really helpful, can you help me to understand ccnp ( routing &switching) how much time taken by you if someone deemands you regarding a ccnp video
\
Hi, Jeremy's IT Lab, great videos I really love the knowledge you are providing to me and others, and please keep up the great work. I still wish I had this when I passed the CCNA back in April 2001. Question about unmanaged switches and when you were speaking in the video about Auto-negotiation between the switch and the device connected and I wanted to know if the same issue of collision occurs if you set manually full duplex & Auto-negotiation can't be detected by the switch. The reason I ask is that I had to displeasure I'm working for a facility that refuses to buy managed switches and wanted to invest unmanaged switches, which prevented us from seeing what was happening on the network.
Very interesting n helpful video...for ccna students
Thank you, I'm glad you think so :)
Need to go through again because am a fresher but great thanks for the time and energy.
Thank you :)
I promise to me if i pass the exam i going to convert in a new sponsor of your work. Congratulations, your work is excellent
Thank you! Good luck!
Every video was a 5/5 on the quiz, this time was a 1/5 XD
this video marks the end of my CCNA journey
lol why
THANKS JEREMY!
Thank you so much!
Crazy desgin and engineering.
