If you aren't very familiar with computer hardware (processors in particular) this page lists a number of places where you can go to get information. Some are good for daily reading just to keep up on what is happening. Others have in depth articles and you should look at them every so often. Lastly there are a few links to basic articles. The way I see it, if computers are going to be the tools you use for your livelyhood through the rest of your life, you should probably have some idea of what is going on with them.
