  1. Hi Professor,
    I believe that, in part 2, the SSD’s have been around since the 50’s. Though the technology offered today is a much better improvement over those.

  2. Very Informative and easy to understand even new learner can get everything easily 🙂 Thanks a lot Professor Messer !

  3. Absolutely FANTASTIC! Thank you, thank you, thank you!

    I live in New Zealand and I nearly signed up with Courses Direct online course for CompTIA A+ and paid for the course, only to notice that they use YOUR videos in their course, that they are charging people. Maybe they are different to your free ones, I dont know but they charge quite a lot of money for the course. Many thanks, your videos are easy to follow and I love them!
