The reason I was curious was because I didn't know what socket it was and which revision it was. I am new to the technical aspects of computers and wanted to educate myself with the details, starting with the computer I have. My next two questions, if any reader has the patience to answer, is what does the "Socket A" signify and what does "Stepping 1" and Revision B0 mean as well? Where can I go to learn what all this means? Sorry for the annoying questions, just trying to get my bearings.
