Introduction to Personal Computers

March 26, 2008

If you’ve ever wanted to make sense of the jumble of chips, cables, and fans inside of a computer, this training module is for you! We’ll start the module with a tour of the outside of the computer, and then we’ll take off the cover and show you exactly what components you can expect to find on the inside of a computer. We’ll finish up the module with a primer on the operation of computer systems.

    Very nice job! I have watched the first two thus far and am very impressed by your own words just because it’s free does not mean it has to be inferior. This applies to what I have seen thus far. I have scoured the web trying to find anything that would be valuable to obtaining the cert. And this is the one place I found that I have come back to and will recommend others to visit as well.

    Great job, Mr Messer.

    After seeing some videos on Youtube, I came across your website. Wow, is what I’ve got to say about it! Very in depth, interesting and showcased in a professional way.

      I completely agree. I can’t imagine how I would make the approach to A+ if I hadn’t come across Professor Messer’s site.

    Thanks for the nice video. I work as an Electronics Technician at the space center. I want to add something to it. If someone is opening their computer, make sure it is unpluged for safety. Do not touch anything inside unless you are wearing a ESD ground strap. It does not take much to damage componets and your computer. I am working for my BSIT and taking A+ at a college this fall. Your videos are a good extra study guide to go with my college course. Thanks again.

    I’m currently enrolled in a very expensive MENTOR oriented computer training institution.

    I surprisingly discovered your site/videos accidently and find them far, far superior for learning from than my entire two months of in-school training.

    THANK YOU for this quality educational service.
