This chapter covered very important material in relation to the current A+ Core Hardware exam and its heavy focus on storage devices and their interfaces. We covered the installation, configuration, and troubleshooting of the major storage devices and their components. There are many Internet sites available that go into far more detail on storage device engineering than is required for the goal and scope of this book. In order to be a proficient computer technician, you need hands-on practice installing and troubleshooting storage devices and computer-related equipment.
