I just passed my CCNA today!!
Awesome! Congrats Joe!
@@NetworkChuck Thanks NetworkChuck. I couldn't have done it without you, Jeremy Cioara, Keith Barker, the Cisco OCG by Wendell Odom, and Boson practice exams!!
nobody asked
@@karmellammy4773 Ok and?
Congrats JOE
Seriously, man, you make learning networking interesting. Thank you so much.
Thank you for watching and commenting. Means a lot!
Couldn't agree more, I used to hate networking but after checking his vids now I understand much more and beginning to like networking. keep it up 👍
@@NetworkChuck Love you bro
I have been taking the IT Google Certification and this is helping me out with the Bits and Bytes of networking. Thanks for qll you fo
Right he really does. I watch a video of this series right before I study and during my practice quizzes.
I am a Cyber Fundamentals instructor and I just want to give props to you! Teaching any portion of IT is hard and you do an amazing job of explaining concepts and never going too deep to confuse new learners. Huge fan and will definitely be watching more videos!
I want to learn so much it’s hard to figure where I fit in with technology I like coding and now I’m starting to like networking it’s all exciting but a bit overwhelming and being ADHD I’m all over the place with no real guidance in college I don’t want to just get another degree and not have a career it’s hard to find a mentor or an entry level job
It’s insane how much fun my students and I have watching your content. Doing a great job Chuck!
I love that you cover a lot of stuff that is taught in my class. You present it in a much easier way to understand and your videos have really been helping me out along the way. Taking my CCNA in a few weeks.
I wish you al the best.
Did you pass?
your seriously an Amazing teacher. Thats your real talent.
I like how excited you are about teaching others, on a career you enjoy. I will never forget watching a speech from Steve Jobs. When he said," you will never work a day in your life if you enjoy what you do for a living". Thank you Chuck, for sharing your knowledge!
I discovered Chuck yesterday.. I don't know what to say! He's amazing.. Thank you for giving me the drive to pick up my Cisco Books once again.. Just thank you.
Two things are sure:
One, the free CCNA course is getting even more exciting!
Two, Network Chuck's beard is growing even bigger!
Thanks for the content, NC, you rock!
Your communication style of teaching is so incredibly helpful to me that I thought I would mention that to you. Thank you for putting out real quality content for people who are sincerely trying to learn and understand. I am sure a lot of work goes into these lessons, so thank you.
From a first year admin who works at a 60+ site company with MPLS, and secondary internet lines, this helps fill in a lot of gaps on understanding why it was done the way it was done.
Thanks for the great video!
I'm starting to learn networking and your videos are so practical, educational and easy to understand! A great extra source of information, thank you so much for the excellent content! Seeing you from Argentina, please keep up the good work ✌🏼
Hey @NetworkChuck I can't thank you enough for your content. It's brilliant. Engaging, entertaining, and really breaks down these concepts in a way that I can actually digest them. I'm also a father of 3 (all girls!) making the jump to IT from the medical field, and I honestly wouldn't be able to do this without your videos. Thank you and bravo!
Please do not stop making these videos!!! You are a awesome teacher. The way you explain everything is very easy to understand. Thank you for making these videos.
This is seriously high quality content. Love it.
I have shared this course with so many people as I have paid for a couple of courses but I don't think they have explained it this well. You learn it and gain the foundation of understanding of how it works to build on when you move on to learn the next implementation.
Exceptional Chuck, I learned these concepts years ago, but you make them click
One thing I loved about this channel is the smoothness of presentation/animation, as well as very clear and concise.
Definitely my favourite channel on RUclips. Learning with you is fun and interesting, I soak in the information so much easier, thank you. Everyone needs to support this channel
Really enjoying your content. I first obtained my CCNA in 2016 and didn't use it for a few years. Now I'm working at a data center and looking to advance so I'm refreshing my knowledge on everything. Really appreciate the level of production that you put into your content.
Wow, I'm loving this serie! Complex topics simply explained! Thank you!
I've been in telecom for about 16years and you nailed the concepts in this video. Well done!
Seriously, this is a great tutorial please continue with these. I'm really interested in it. Great explanation with hardwares.
I remember working for the nations largest bank and we needed communications for the ATM network around the globe. Leased lines wer mad expensive, so they launched thier own satellite! Problem solved. I worked on the ATM support services which monitored EVERYTHING an ATM can do. All rhe ATMs were in constant communication with my particular system. The ATMs were polled all the time like "are you there?" "Yes im still here. Alive and well" these polls happened at least 1x second. If the ATM failed to respond within that second, it was dropped to a slow poll list (1x every 5 seconds) depending on where the ATM was located if it wasnt heard from in a period of time, an alarm was generated, and a status MSG was sent to the NOC for investigation.
Some satellite delay times were 5-7 seconds and timeouts would have to be adjusted.
Without giving company secrets away, one key, is very tiny data packets. This made the ATM network one of the most reliable in the world. Oh we designed and built our own ATMs as well
There is more than one classification of WAN. There is public WAN (which includes internet) and there is private WAN (MPLS, SD-WAN, IPsec tunnel, Frame Relay, Dark Fiber). This is a good topic to share because its something I had to learn on the job. None of the educators on networking technologies really explain it at the level that a 5 year old can understand. Great video.
I've decided to leave a comment on each video through the series :) . Another helpful, informative, and engaging episode. Chuck, thank you so much for sharing your gifts with us! I'm so glad I found you :)
Hey. I am 17 years old and I am loving this. I am just doing this to gather some knowledge, but oh god this is goooooooooooooooooooood!
You can tell Chuck is just a great guy all around, the kinda guy you'd like to have a cup of coffee with.
Love this series! Keep them coming Chuck. It's truly appreciated
I just came across your channel today. I do a lot of network engineering (not to your level) and this is such a fresh change. I enjoy your excitement and energy discussing what for most is a mundane topic. Thoroughly enjoyable! Keep up the great work!
the kind of way you teach is my way of learning make stories to remeber.....and thats why i just come everytime to see your videos.
From what I have seen in the wild is the Corp office and Data Center will use a MPLS and all of their "coffee shops" will just be connected to the Web with Static Addresses so a Tier1 or Tier2 Tech can remote in for troubleshooting and such. Included in the MPLS will be a Call Center and possibly a Managed IT Support firm. All depends on the type of company it is. I use to see AT&T would bring in two Fiber Lines for the location then use a T1 connection manage the Fiber Connection, ATT hates sending out their Techs.
I got training in private institute but I didn't understand OSI model but with one lecture of you make it so easy for me to understand it. Thank you Boss you are a genius...
I've learned so much in 2 days of watching this series, than what i did in one of my session for a class in a span of 6 months. This is way more fun to learn than in one of my classes. Thank you :)
I have been a wireless guy and want to switch my career and want learn wan .. i saw this video and u totally nailed it
Awesome videos man! Really appreciate what your doing! I disconnect from my pi hole when I watch your vids lol
My favorite comment! Thank you Robert!
I have always been confused about how WAN technologies work. I just needed a visual representation and a demonstration to understand it and you provided that. Thanks!
You know Chuck got really excited explaining something when he throws away his pen.
Awesome video Chuck, I've been learning a lot from you lately. Thank you :)
Thanks to you chuck now I love network. I’m still preparing to start an IT career as a help desk. But I already want to become a network admin and sooner than later break into cybersecurity. This is the path I see as the best one. Thanks for all you work and content.
Love the CCNA content. This has been some of the most useful, informative content I've ever found on RUclips.
Man I wish i found your channel sooner, the way you teach passionately encourages me so much. I hope you never stop
I was looking into CCNA and other networking jobs in my country that I might take upon in the future (I'm still in college) but most of them require 1-4 years of experience. Can you maybe give me advice on something to do before i get qualified for these jobs? Im trying to learn job-worthy skills before I graduate
MPLS (multi protocol label swtiching) connects your LAN to your ISPs carrier network. But you share the same lines with other customers.
It is private because their your data travels through its own virtual ciruite through the use of labels that keeps your traffic separate form others.
Customer edge router
Provider edge router
E-line (uses Ethernet virtual circuits) connects swtiches between your LAN.
E-Lan
E-tree: everybody connects to the data center
Site to site vpn (goes over the entire internet) adds headers and encryption to packets
QoS: quality of service certain traffic is prioritized
DIA: dedicated internet access
Yet another awesome and informative video. Looking forward to next week, and thanks for doing this series! ☕
Alright, so I know you highly recommend Boson, but I've also heard you mention CBT Nuggets. Any advantage to one over the other for courses and prep?
When chuck says at 14:08 "What's wrong with that guy",... I just could not stop laughing. I had to pause the video and put this comment. Chuck, you are an amazing teacher !
I've set up a wireless WAN to connect my home to my workshop (around 3.8 km away). I don't have line of sight so I have set up some 5.8 GHz gear at a comms site I have access to. I also have some amateur radio equipment at the comms site (MarineTraffic AIS receiver and FlightRadar24 receiver).
It's nice to be able to access network resources at home (including the internet) when I am at my workshop... it's just like having a long (but slower) Ethernet cable between the two locations.
Love my WAN!
very much appreciate the way you break everything down AND I feel like I am watching an interesting youtube video versus a boring class lecture. Thank you! I have hope.
Explanation using real examples of how the things are done and how are evolving is great! Thanks for the great work, ure awesome!
bro with you is super easy to understand all of this
I just got really excited because I picked the last three, and was only able to half-listen to most of the video. The analytical breakdown of the question makes a lot of sense to me. I need to rewatch and get more of the meat, but knowing I would already get even this one question right is encouraging.
"Metro" connections are also used to connect two datacenters in the same city or different parts of a city. That allows setting up at least two node (server) metro clusters for high availability services (database, application etc.). Physically it can be ethernet or fibre channel, usually two lines (yes, also for high availability).
Thank you for making these videos! I love them and watch daily. Got my CCNA during lockdown through netacad, but there was no hands-on due to the lockdown. Your videos put everything in perspective. Many thanks.
I kinda like Site to Site VPN because it is simple, cheap, and portable. Even though there is a possibility of poor connection, there is still a QOS option to prioritize the traffic.
You are awesome. How you explain this stuff with your coffee break gets me in stitches.
For real you make me want to learn more about networking. I recently setup a ethernet lines to all ethernet ldevices after watching one of your RUclips clips.
Using switches, & router to the moden & so, far no disconnection from the WIFI. All seem to be working seamlessly thanks to you.
You are the Man, The Top G.
Anyway Thanks a bunch. I Still will be watching your content for fun & to learn from you.
Coffee break time😂😅.
More please! Can't get enough of these types of videos.
Truly enjoy the questions sections, especially when I get them right😁
It took me about a week to get through this entire video with an acceptable rate of retention but by golly I did it! Thank you so much @NetworkChuck , these vids are pretty much the most dope
Thanks for taking the time to put these videos out. You answer the questions I've always wanted to ask and you do it in a way that I can understand. Truly ELI5.
super clear - I have asked some of the top network engineers in the world the same questions and they could not convey this clearly.
Wow, another great lesson! Music for my ears!. Thanks for sharing your knowledge!.
This video is awesome. I am currently doing an Internet Fundamentals call at University and your videos have been really helpful to help me study for my final exam.
C'est juste amazing ! Merci pour les cours et surtout cette façon très intéressante d'enseigner,
Waiting for the next video!!!
Please make a video about what we are actually paying for when buying "internet"
You honestly don't want to know. It's a jungle and I am surprised a ISP or WISP know what they are doing.
Speed for the most part. since capacity is only limited by our ability to put up more satellites and generate information.
I am talking about when we buy internet for our sim card
@@mohammadfoadtavakoli7118 You are paying your isp to use their services and infrastructure. When you "buy" data for your sim card, they give you access to the internet via their infrastructure. So technically you're not paying for any physical thing, just paying for permission and access to use their service to access the internet.
@@mohammadfoadtavakoli7118 you are basically buying a ticket to access infrastructure its like paying to use high-speed highways
I remember having a "Metro E" connection between my company and the datacenter, but they where in different cities 120 km apart. We rented dark fiber com the railway company, and literally stretched a fiber cable from the office to the train station (+/- 1km) connected it to their fiber patch panel, and they some fibers allocated to the same datacenter we where using, se we had "the other end" on our dedicated Rack.
Chuck’s videos always make my day!!! Keep up the awesome work!! 🙏🏼 I think that everyone loves and appreciates his calm voice and the funny yet understandable way he explaines everything!! ♥️♥️ sending love from Greece!
You explain things so well. Very easy to follow. thanks so much
Great teacher seriously ! and more awesome that you help everyone to learn from youtube for free !
You make learning Networking and Networking concepts extremely fun 🤩 as well far more easily understandable with your clear understanding visual drawing board.
whenever i forgot networks i remember coffee..though its amazing!
Entertain while educating , you make confusing topics easier to understand :)
My university has 2 buildings 4km apart and before they were leasing the line. Now they use VPN software/hardware since optical internet is very cheap in my country. My computer networks assistant is actually a network admin on the universty so he learned us how it all works. The reason why private universites are much much better then public ones
NetworkChuck, just wanted to say kudos for breaking down the information into nice bite sized chunks and making it deliciously edible. Being a self-taught technician with no formal training, and I have run into about 80% of the networking scenarios you speak of as I meandered throughout my career. Having made the decision to start looking into getting a CCNA and other Cisco certifications, I ran across your youtube videos. Excellent information in a fun and informative manner. Again, kudos to you, for making this information fun again.
You are 100% correct on the key points you presented in the video. SD-WAN is still an uncharted territory for most network admins. They have heard of it but afraid to make use of it despite how easy it is to implement. So maybe a future video on how to make use of SD-WAN.
finally, i hope this ccna cours end before ccna exame
thank u chuck 🙏
THANKS SO MUCH NETWORK CHUCK IM 17 N STILL IN HIGHSCHOOL AND IM LEARNING SOMETHING THAT I HAD TO WAI 4 3 YEARS TO START LEARNING
This is Lit bro. Thank you so much. As as for dwindling the cable from the ceiling 🤣🤣🤣
Learning a lot from you, I have already completed CCNA in R&S but never had so awesome learning time and so good understandable knowledge...
men you are amazing. you are my all time favourite ! i wish you even more success in your career. and im about to take my ccna exam in a few weeks.
Great stuff! I plan on taking my CCNA within the next 3 months!
Chuck thanks again for a fantastic video and easy to understand explanation. I have recently moved roles within my organisation and we are in the process of a migration project, this gives a great overview. Thanks from the UK 🇬🇧
You're amazing, I've been wattching all your CCNA videos and I love them, fantastic!
Waiting for next video , YOU explained the topic in very realistic way. This kind of knowledge we actually need.... Keep doing this.... Thnx for this CCNA playlist
Are you kidding me, i got both of the questions right.. Brother i love your method of teaching and your voice is very friendly...
The Best teacher I have EVER EVER seen!
I got to say chuck... This content right her... this... MINT!!!
this content is sooooo goood!!! I've been taking Bombals Udemy course and its good, hes ok no complaints, material is solid. BUT you, Chuck my dude, you got that special touch, you got that special something... a special knack... you know? you explain things better than most people and you give solid real world explanations and break down these complex subjects so simply.. loved this stuff man, keep it up! just got some your coffee to support this magic right here.
Great videos, not going to be a network engineer but as a programmer helps to get a deeper understanding of networks other than thinking of them as a "dumb pipe".
As I'm subscribed to similar tech channels, the algorithm suggested this video..
I already knew about MPLS virtual circuits, but your style and concrete examples for how all those others work... Instantly subbed!
I'm not currently doing or going for CCNA, but perhaps it might be a good path to go...
So I already have my CCNA, but now I'm going for my Bachelor's in IT, with a concentration in Telecommunications. It's been a moment since the CCNA, and I'm definitely (sadly) not using the skills. One of my classes today had a lecture on these exact technologies. You explained it so much better, made it more fun, and I actually want to watch it, instead of it being a prerecorded lecture that I *have* to watch
@NetworkChuck you just ruined my entire childhood - everyone at school and outside firewall way saying,, the Internet is wan!'' - ruined ;(
Well, as a consumer, thats all you need to know. Its not like conmsumers are allowed to know the exact config of their lines nor are they expected to know the difference :) Working for a fiber ISP i've come to understand that what most people think they know is that more Mb/s = stronger wifi reach...
Dont worry =P
I only discovered your content recently and I got to say you definitely make learning about all this really interesting and fun. I already have most of this under my belt already but even so it's just great to even use your content as refreshers from time to time! Keep up the fantastic work!
I learned a ton on this one. The others so far have been good but this one was so helpful
You can't get ATM or frame relay from many telco providers any more. CenturyLink will only support existing circuits, you can't order new. What everyone is doing now is either leasing you a pair of dark (unused fiber) or a PON.
This guy is legend, love it
Thanks Chuck, it really help solidify the concepts in my brain when you use real world scenarios.
I mean I can't understand how such awesome video even gets a dislike ...those 3 guys needs to look into themself first then hit the dislike button...
Thank you once again for your content . Most respect how you help everyone simplified for everyone and keeping it insperational and entertaining.
A great video. Thank you Mr. Chuck.
Thank you so much I love your style in explaining it's really awesome... Thanks again.
Thanks so much for concepts, made my learning easier for an application guy like me.
@networkchuck You are just awesome. I love your lessons. I find myself giggling out loud at your analogies. Great work man.
I have heard of WAN being used for connecting networks of different sites but it's usually only practical if they are somewhat close distance wise. If the sites are too far to run direct lines then they will use Internet as the medium for communication.
Man!!! God bless this guy hahahaha He is awesome ...
