Have you ever wanted a “technical-to-English” dictionary? Sometimes we find that while knowledge is paramount, it isn't everything—we still have to make other people understand what we're talking about, and vice versa.

This lesson covers the most basic physical components of a computer system, the basic elements of the operating system, and how files are written and stored. It also provides an introduction to what happens when a computer starts up, which is key to troubleshooting a computer that isn't starting up properly.
If you think you already know this material, as a “pretest,” try your hand at the Computer Theory and Terminology Worksheet included on the CD (CTT_pretest.pdf). If you complete the worksheet without error or consulting the text, congratulations! You can skip to the next lesson.
