Introduction to Personal Computers

| Mar 26, 2008 | Comments 36


Let’s start with the outside. What’s on the outside of the computer system? When we start looking at a computer we can see a number of things that are found on every computer. The first would be the monitor. We need to have some way to see what we’re working with; the monitor provides that functionality for us. The picture here is of an LCD monitor. Monitors can be very small, very large, can be a cathode ray tube (CRT) or an LCD, but the purpose is still the same. The monitor shows us the output from the computer system.

We also usually have some type of keyboard interface. The keyboard will allow us to type and provide input to the computer. Where the monitor was providing output, the keyboard is an input device – very much like our mouse. They keyboard is providing direct input of the letters and the mouse is allowing us to move the cursor around the screen so that we can act and react to what we’re seeing there.

And finally we have the computer itself. Sometimes you’ll hear this referred to as the CPU. “You need to turn on and off your CPU,” but in reality there’s a lot more inside of that device than a CPU. So calling it a very generic term, the “computer,” is probably the best way to go about it.

      Very very good…thanks!

    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

  • Robert Pruitt

    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.

  • 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.
