Introduction to Personal Computers

| Mar 26, 2008 | Comments 36


Let’s start with the power supply, at the bottom left. That power supply on the backside, facing the outside, has a place where we can plug in our power cords and get power from the wall outlet. The power supply is responsible for providing power to our motherboard, our hard drives, our floppy drives, and anything else that might be inside of our computer. You can see on the right side of that power supply there are some black wires, some yellow wires, and some red wires coming out. Those are the wires that carry voltages to power other components in the system. If you followed them back, you’d see them plugged into the motherboard, floppy drives, and our hard drives.

    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.

    Hello,

    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.

    • Alexander Dedman

      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.

  • victor

    Very easy and very clear the way that you teach us about the first module.

    Thank you

    good video getting ready for test

    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.

This is an accumulative second chance in life for me to succeed and i am very appreciative of the efforts you have made to be a part of that. Thank you!

    Hi Professor Messer,

    I was halfway through reading my thick A+ certification when I came across this site.I watched all of your videos in about 2 weeks and with solid practice on the test questions I signed up for my exams.

    Thanks a million to your great explanation in these videos I was able to ace the 601 and 602 exams. I would definitely recommend this site to others.
    Cheers

  • Ray M

    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.
