    Keith Barker is one of those rare people that understands the material well enough so that he can explain it in terms that everyone can understand.

    Where have you been all my life? Your energy is so cool. Thank you for explaining things so simple. I've taken Cisco classes in college. I am now studying to take CCNA cert. using CiscoPress books. Your knowledge and CiscoPress will make this journey so much fun! Love it! I'm now following you on TH-cam and Twitter.

    Keith, you are a phenomenal instructor. I've taken the entire 200-301 curriculum over 3 quarters of community college, and had ZERO IT understanding going in, didn't even know what networking was, really. Needless to say, I missed a lot, and now, using your videos and labs for review, a lot of concepts are making more sense. Thank you so much.

    Keith, I hope you are still on here teaching because I think you're great putting it in lamens terms and helps so much. I'm just a couple of years behind you in age BUT I'm just starting in the IT world. So I'm grabbing onto your coat tails. Barely could use a computer and now in just a few months in college Cybersecurity I've learned a ton but processing it all is difficult so I like to watch people explains things better than self teaching in college. You're given an assignment but not taught nothing. So great folks like yourself help soooo much.

    Keith, I absolutely loved the energy and effort you've put into making this video! The concepts were amazingly practical, easy, and fun to understand, especially from a review standpoint wherein these same concepts didn't make as much sense the first time I learned them.

    Hi guys, quick question. I'm a complete newbie to the world of IT. Is this course the right place for me to start or should I be getting a ComptiaA+ first. I'm so confused and all help is appreciated. Thanks!!!

    • @KeithBarker
      @KeithBarker  5 ปีที่แล้ว

      Thank you for the question. If you are brand new to networking, you may want to consider CompTIA Network+ followed by the Cisco CCNA. There is quite a bit of overlap, which is good for reinforcement.

    So will this playlist prepare me for the 2020 updated CCNA exam? Right now I'm using Jeremy's IT lab courses,I'm questioning whether to read the Todd Lammle book or not...

    • @KeithBarker
      @KeithBarker  4 ปีที่แล้ว +7

      Thank you for the question R T.
      Jeremy's IT Lab courses are wonderful! I would recommend at least 1 book as a reference as well. Check the feedback on Amazon regarding books, to make sure others are recommending it as well. I've heard that Lammle's book is a good one.
      This TH-cam channel is intended to be a valuable resource while learning the CCNA content, but not an exhaustive end to end coverage of every possible topic.
      Thanks for the question, and happy studies!

    @ErichBProductions 2 ปีที่แล้ว

    It's interesting you say we don't need to memorize the OSI model. All the other resources I've used to learn networking emphasize the importance of knowing the OSI model because it's the model most network engineers use for communicating issues on a network. Would you say TCP/IP or the "actual" model is enough for the CCNA but we should know OSI for working in networking or is TCP/IP /"actual" model enough even when diagnosing network issues?

      Thank you for the question Erich.
      What we use today is a mashup of terms and layers from BOTH the OSI and DOD model.
      Final result is:
      Application Layer
      Transport Layer 4
      Network Layer 3
      Datalink Layer 2
      Physical Layer 1
      And it is important to understand the layers above for designing, managing, and troubleshooting networks.
      Cheers!

    Question: whats the difference between protocol and standards?

    • @KeithBarker
      @KeithBarker  4 ปีที่แล้ว

      Thank you for the question Eliezer Binyam. Protocols are simply rules. If 2 devices use the same protocols (rules) they can interoperate or communicate with each other.
      Sometimes groups or teams of people get together to create standards. There are some standards for network communications, including Ethernet and WiFi. Then when companies build their products, if they follow and comply with the standards, the products from each company should be compatible with each other, if they both followed the standards closely enough.
      Hope that helps!

      Thank you for the question Alexander. I would recommend a good book (check the reviews on Amazon) and a good video course, and then practice hands on wherever possible. Packet Tracer is free and can get the job done.
      My channel here on you tube and this playlist ogit.online/sloth can help reinforce the concepts you are studying.

    • @KeithBarker
      @KeithBarker  5 ปีที่แล้ว +1

      Great question. For the CCNA all you really need is the free packet tracer simulator from netacad.com You can sign up for a free account and start using it. If you want to buy a practice physical rack, there are several companies that do that on eBay. Glad you are here, and enjoy the CCNA playlist: ogit.online/sloth

    Thanks!

    • @KeithBarker
      @KeithBarker  4 ปีที่แล้ว

      Thank you Hakim. The playlist here ogit.online/sloth is not an exhaustive all inclusive coverage of the CCNA, but rather a list of videos to assists learners. The best way to do better with labs is study the technology, and then practice practice practice. All my PT labs have TH-cam videos that walk through the solutions. There is a separate playlist just for the PT labs ogit.online/pt-labs
      Happy studies.
