All about Hardware

I learned alot about computers in general in our class lecture by Larry Hechler.  Specifically, I learned alot about what is inside a computer and how important backing up your computer is.  I have always been worried about the possibility of my harddrive crashing and losing all of my music and school papers and such. I was detered from buying an external harddrive by their cost - close to about $100.  Now I am determined to do more research on external harddrives and buy one to ensure that I don't lose everything that's on my computer! I also learned about the battery life of a laptop.  I have heard that you're supposed to let the battery drain before plugging it back in but I really never paid attention to this. Now I know that you need to definitely drain the battery before replugging the computer in and also that it is important to do this at least once a month if you leave your computer constantly plugged in. Hopefully with this new knowledge I can be a better computer owner and buyer.
