Discussion of Chapter 7: Storing Data: Disks and Files

See the slides in PDF format provided by the authors of our textbook. I skipped slides 17 and 19, which cover straightforward material in the text, slides 26 and 27, which cover catalogs, and summary slides 28-30. We don't need to concern ourselves with catalogs now, but please review these slides to get an idea about them. Note that the costs of RAM and disk on slide 3 are VERY old.
