  1. Thank you for the very easy to understand explanation about Networks. I really learned a lot. Your analogy of people talking makes it easy for me to understand how computers talk.

  2. Please make a video on ipconfig. I mean explain everything that comes up when we pass the ipconfig command on CMD.

    Thanks for this Great intro, I learned a lot from your way of explaining and simplifying the concepts in this video. I hope you do a whole course in Computer network soon. you will help a lot of us how are interested in this subject if you decide to do the full course.

  6. So well explained…even a kindergarden kid would understand…cisco certification synthesized…

  7. Chenar Abdulla

    fantastic explanation. Please make more videos about networking and the basics.

  8. Business Opportunity in Ruvol

    I have invented a Board Game [still unpublished and not yet out in the market] that I believe is guaranteed to be as challenging and exciting as CHESS. I called it “RUVOL.”

    It is my hope that one day Ruvol may surpass chess as the “Number One Board Game in the World.”

    The weakness of chess is it always starts in fixed positions that the opening moves become “memorizable.” In fact, not a few have so mastered the moves that they can play against their opponents “blindfolded.” It is for this very reason that the great Bobby Fischer introduced his so-called “Fischer Random Chess,” where the starting position of the pieces is “randomized” to make the memorization of openings impracticable. Fortunately, it is also for this reason that I invented Ruvol where “every game” has been calculated to be a challenging one to play.

    HOW IS RUVOL PLAYED and HOW YOU CAN MONETIZE IT?

    I detailed everything in my YouTube video. Here is the link: https://www.youtube.com/watch?v=jcqth0m3-R0

    BIG MONEY POTENTIAL IN RUVOL!

    It is worthwhile to note that the people who play chess will be the same people who will play Ruvol. In my Google search, I learned there are around 800 million chess players in the world. Even just a small percentage of these 800 million is good enough to earn big money from Ruvol either as an ONLINE GAME BUSINESS or as a PHYSICAL PRODUCT DISTRIBUTOR.

    Thanks and God bless!

    I really think names of teachers should be included in videos 😢 Explanation was so good

  11. Mr Chike

    Wow. Now I understand the statement. If you can't explain it to a layman. Then you don't understand it. Thanks. It was precise & straight to the point.
