Computers are so frustrating!

I'm really starting to think that as much as computers can make life easier they are a living hell. I am taking this computer course right now for my Library Science program and I completely bombed the midterm. Yuck! I am doing fine with all the assignments but the midterm just kicked my butt. It asked very technical questions that had me looking at the computer going "huh?" I think my problem is that I am not taking enough of an elementary approach to this class, I should be doing vocabulary terms every week because that was basically all that the test was. Maybe for the final that is what I will have to do. I'll just write out vocab words for each chapter and then go over a couple times per week and then perhaps by the end of the semester one or two of the words may have stuck. Or perhaps the computer techie thing is just not for me. I can understand the programs and how everything runs and how to use everything, but I cannot for the life of me understand or remember what all the parts are called, for example RAM...what? I have no idea. Do I even need to know this to be a librarian? I know that I need to know how to use the computer, which I do. I mean for goodness sakes, I work for a compuet company right now. But if I need to know the inner workings of the computer or how it runs I will take it to the Geek Squad at Best Buy. Scheesh, all I know is that I better pass this class despite my crappy midterm grade because I cannot afford to lose out on the outrageous amount of money that I am paying to take this class!
