    You say no one watches these compared to your talking head videos. I just want you to know that they are still important and we appreciate the time and effort you put into making them.

      Exactly, there've been so many talking head videos that I stopped watching Eli's channel. But I love his tutorial videos, so I'm back again, being a great fan of his channel.

      I really liked the talking head videos but they're getting too long. These are great too. I like Eli's no-nonsense approach no matter what he's talking about.

    Literally took a break from an actual Cisco training just to see Eli explain the information in his own way. Definitely appreciated as humor keeps you engaged with the actual information as well real life scenarios.

    Studying for a test I'm scheduled to take later today and of all the studying I've done your video was by far the easiest to understand. Watched this one, and your 13 year old one and they are just so easy and full of information that's actually useful. Wish I'd have found you sooner!

    I remember watching your old OSI lesson video, a few years ago, and it was very informative. Good to see you made an updated one. Nice work. I really enjoyed watching this. It was very informative.👍

    @saraht6143 ปีที่แล้ว +1

    Thank you, I came across your networking videos that are over a decade old, I am glad that you're making modern videos on the subject with all your experience. The osi model as a mentality , which also prevents overwork, which is prevalent in the Technology industry, is also a nice way to look at this video. a large part of troubleshooting is anticipation and knowledge, so it's nice to hear that 99.9% of problems(hard fails?) can be directed at 1 of 7 layers lol.
    unfortunate that you had to arrange a flight to plug in an ethernet cable, at least we have video-calling now!

    The actual OSI model has helped fix more issues as a network/systems engineer than I can care to think about.
    Advice from an old but young looking IT dude to the "non-boomer" peeps:
    I'm always learning but as a tech professional of 15 years, do yourself a favor, learn each topic deeply so that you are not just memorizing it. When you do that, you realize that when you're facing an actual issue that needs to be resolved, you will be better prepared to come up with solutions and implement them like a true professional.

    As your video ended, I noticed a roll of what appears to be toilet tissue with the letters “CCNA” on it. Dare I ask what that means? 😂

    Would it be possible to first use the tcp/ip model first and if it didn't work use the opi model? Or would not not be efficient enough?

  • @wisenber
    @wisenber ปีที่แล้ว

    Wow! Haven't heard anyone mention the OSI model in quite some time. I still remember studying that for my Netware 3.x CNE. The cool kids from TCP/IP land used to make fun of me and take away my 3Com cards in the sysadmin playground as they insisted there were only four layers to worry about. Those bullies didn't even care if the NIC was bound to 802.2 or 802.3.

    Some guys explain the OSI model with changing characters and foam trains? Others describe it as something similar to a mail delivery system. I guess at the end of the day, Eli gives the concrete specific examples I was looking for. This is the best damn description of the OSI model and re subbed for more examples from future videos. You come across as an asshole at times, but I guess that means you speak my language lol.

    Your tech videos aint getting much views not because ppl arent interested in your tech videos but other factors. Here's my suggestion:
    1) clickbait titles
    2) 100% focus on tech, any non-tech will simply dilute your channel, create a 2nd channel for non-tech, that way ull do well for both channels rather than mixing both in 1
    3) Project based videos
