Introduction to Personal Computers

37 Comments




In this module, we’re going to talk about an introduction to personal computers. These module topics come directly from the CompTIA A+ exam objectives Section 1.1 which talks about using personal computers. We need to be able to understand what’s inside of our computer systems to be able to do maintenance and troubleshooting. This is going to be a good introduction that provides an overview of the outside of the personal computer. We’re going to open a system and I’m going to show you what’s on the inside of the system. Finally, we’re going to go through a short primer of how computer operations occur using all of these different components.

    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.

      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.

    These videos are great descriptors of your personality, knowledge, and generousity. I start my software courses tomorrow morning to be then followed by hardware as I work my way towards A degree in the IT field. 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

    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.
