[@truthfinder7549]

These are the ports used ? are they same in every network? Can you change the ports?

[@TheBigMofaman]

@@truthfinder7549 you can configure different ports -- these are the default ones that are normally reserved for these applications

[@AsmodeusMictian]

The difference between TCP and UDP in the best way I have personally ever seen/heard: TCP: Cradling your baby and gently putting them into their crib, ensuring that they are tucked in and comfy. UDP: One word... YEET! I've yet to forget the difference after being shown that lol

[@SadCarBitch]

hahah I know that is super silly but that really is helpful

Nice! T for toddler

[@bojanglesinthaflesh]

Now I for sure know the difference now!!! Thanks Mane!!!

[@morris859]

I swear, No one does it better than you, learning is more interesting on this channel. Thanks and keep up the good work buddy.

[@magetaaaaaa]

Even if you have been in the field for a long time it can be valuable to come back to these videos. In school a lot of concepts are abstract and lack context. Once you see them out in the field you understand them better. Then you come back to the education with the knowledge from working in the field and a lot of light bulbs start to come on.

[@JJFlores197]

Yep. I fully agree. I took a few Cisco courses years ago at a community college. The instructor was pretty good. She gave a lot of examples, but they weren't really tangible. The hardest part for me to grasp (other than subnetting) was the physical infrastructure of how routers and switches and patch panels, etc are all laid out. It wasn't until my 2nd IT job at a school district that I started to get more hands-on work with the network infrastructure that I started understanding a lot things.

[@arminriverol4286]

Chuck this is a asome illustration bro.Can't get better than this.

[@cannafarmer]

Eli the computer guy has very good info as well. Hes much more chill and laid back if you would like a different approach but he is super knowledgeable. Of course network chuck is awesome too

[@jacoboruiz7533]

I'm binge watching this whole CCNA series right now, you're doing an incredible job making this subject entertaining and passionating, keep it up !

[@jaydenkorhonen3167]

Thank you so much for this series. Combined with subtitles you have all 3 visual, reading and listening learning techniques combined into one. Incredibly efficient and easier to grasp these concepts compared to the classes I'm currently taking. All. For. Free. A huge contribution to the community and a legacy to leave. We appreciate you!

[@SadCarBitch]

for sure, I agree! I have had several "lightbulb moments" during his videos about concepts I just cannot seem to grasp in class

[@Cesar-kw9fh]

So far I learned more in matters of hours than I learned in entire semester in my Cisco classes.

[@sakumiko9890]

Chucks may not know this. but he does not only teaches me things that can help me make a living of, but also helps my depression with his cheerful personality.

[@hycyber-ytb]

Bro, the KZbin ad jump out at 9:56 is mind blowing, the best ad timing I've ever seen in my life so far🤣, great video btw.

[@BelgianDneprGuy2003]

I can't belive how much I've learned purely watching this series. I'm currently following an IT course in college (2023, putting this here for future references) and I have learned more about networking in this course in few days time, compared to what my teacher is explaining during class for the last few months. The way you teach this, is literally how teaching this should be. It's fun, it's packed with lots of difficult info broken down into info that is easy to understand and remember, the simple and very clear sketches are such a big help and the 'interaction' with the class / community is how many more IT teachers should be interacting with their students

[@BeEmpathic]

19:28 - As you wish, Chuck! Client listens on 68 and server uses 67. Thank you for spreading your knowledge

[@ryanamberger]

When we break down network communication (or any computational communication for that matter) like this, its mind boggling how quick and seamless it all works. Heck, how it even works at all. It is beautiful to be completely honest. Maybe being able to appreciate it is what makes all of us IT folks techies in the first place.

[@choirulrohmathidayat262]

hmmm, a dark magic is doing all of that..

[@connorhill6414]

CHUCK is the greatest teacher! you made me go back to school for cyber security, and now I teach Information Technology to high schoolers; you're amazing!

[@codyenders3016]

Your content is very solid and I just wanted to say great job!!!

[@geleaugelin8202]

I have been studying for the CCNA for 4 months now.... And your videos are exciting and keeps me want to learn more. It is not boring at all and builds my confidence .

[@chadgatlin]

I have tried a few times to start CCNA study and every time I got bored out of my mind or bogged down within a couple of hours. This course and your teaching method has turned that around for me! This is excellently presented, the best course experience I have had. I am actually excited to learn Networking and have fun with each and every video! Great job and thank you!

[@petikoncz7178]

I am Currently studying Cyber Security in Sydney and watching your courses and videos about some topics that we cover, and you can explain a 4 hours long lecture in 15 minutes and better than they do In the University. Your videos are great quality, clear and super easy to understand. Keep it up mate!

[@brianminogue8014]

I 100% agree with you! I am in the same studies and could not agree more!

[@karpetkicker]

Your personality combined with knowledge, experience make you one one of the best instructors. A modern take in comparison to other IT instructors, not taking anything away from them of course because I appreciate the effort instructors put for us to learn without college THANK YOU!

Congratulations on your 5th child.

[@ugetridofit]

What i would love to see someone address is how things on the network keep from talking over another. For instance, say on my network I have 3 people streaming 4k videos, while I am doing google searches, and then I also have 10 other networked devices like 4 IP cameras streaming video data to my DVR, and other network devices. That is allot of data flying around through the switch. It seems obvious that the switch handles data to each device in a controlled manner so that one does not talk over another. But that would think that this would mean that each port on the switch is time slicing the data to the WAN port.

[@davidvo2235]

Is there a way I can get all the ccna videos at once if i pay rather wait once a week for a video?

[@retsvus]

@@ugetridofit Quality of Service. QoS Packet Scheduler enables management of the network bandwidth which monitors the importance of the data packets. This depends on the priority of the packet and provides lower or higher priority or bandwidth levels to the connection. QoS must be supported on both sides of the connection.

[@networkengineertechchic5018]

Thanks

[@Motivation2Invest]

I studied my CCNA years ok and remember it being much more difficult, you make it seem so simple! Exceptional Chuck.

I started a cybersecurity degree in 2020, too. Had to take 3 quarters of Cisco classes for CCNA, also, only to find out I'm way more interested in networking than security.

[@rezajami200]

Hi you. I've talked to a lot of people about the network foundation and I have to say someone has understood the foundation who can explain the whole thing in super simple terms. You absolutely do. I always understand the whole thing better through your videos. PS: my English is not the best my mother tongue is German, even there is super to earn

[@jaimegy3968]

GOD BLESSED THIS MAN WITH AMAZIN TEACHING SKILLS

[@rpruneau68]

Preparation and Practice is essential. Hundreds of hours of study and many years of teaching and the ability to explain a technical subject in non-technical terms are key. And yes; Chuck has mastered these skills and the art of delivery said message.

[@CYBERINSIGHT]

This actually complements a video I put out today that was a practical lab walkthrough of how DNS works. It's always great when folks that get aha moment when we see how all the different protocols work together and why certain ones use TCP and others use UDP for their transport layer protocols.

[@ketatgenhorst]

Trying to also learn how to teach, I have to do that in my current job and it is simply assumed "You know something, so you must know how to teach it." Watching you is teaching me to teach. The energy level - sound effects.... oh, something just happened worth noting Let's have some coffee - you just learned a concept So much to learn, really appreciate these videos.

[@hectormendez6391]

Gracias Chuck, estoy estudiando con los libros de Wendell Odon pero ver tus videos me mantiene motivado cuando no tengo ganas de leer la teoría. Definitivamente voy a invertir en tus patrocinadores. Gracias Boson por patrocinar este video.

[@djeshorty]

You are THEEEEEEEEEEEEE best teacher ever! Everything is clicking and its making me more excited to learn. This is giving me the confidence to take my CCNA, finally.

[@oMeGa0122]

Guys if you were just listening without watching while trying to memorize the reserved ports; please note that he unintentionally said some of them wrong. Great and lovely video BTW I just started to learn CCNA from you sir ❤️

[@MumzInTech]

I'm getting addicted to your videos, teaching and voice .. thanks for your efforts.

[@izakj5732]

Hey Chuck, really appreciate your free course, I've done a networking exam inside of University and got a First-Class Honours grade and I've got a few more exams to come before I go for CCNA etc. Thank you for making this accessible

[@mpn5124]

This channel is exactly what a telecommunication master student needs ! Thank you so much for making great content and adding your own taste to every sentence

[@wingkeung9979]

One thing I wish other youtubers would use is more analogies. It’s an effective teaching tool instead of dryly explaining things or just using jargon. Can’t wait til this is all done and complete!

[@juliagiulina]

You are one of the best teachers I know. Thanks for your great work! 🎉

Love this series. I was told to get Comptia Security+ certificate for a job right out of college. I am hammering away but I needed more Network experience. So helpful.

[@dkfailor]

First of all, thanks Chuck for producing these videos with the excellent content. They are both fun and deeply instructive without any "fluff". I was following your tutorial on my own PC with Wireshark, and I noticed that instead of UDP, KZbin is using the QUIC protocol now (RFC 9000). I was not familiar with it and so I looked it up--apparently, it is a protocol that is built over UDP that includes security but is faster than TCP.

[@scottryder2598]

Wow chuck you explain stuff so well it sinks straight in thanks so much for your efforts Brilliant

Just wanted to say thanks for this series! I have my degree in network security, but dont have my CCNA yet, this is a great refresher of the basics!

[@bemljj]

Wow! this REALLY cleared up layers 6,5, 4 for me. Love analogies, and the actual terminology examples. Will keep watching even though I feel more confident with 1, 2 ,3.
