This isn’t a podcast but a series of lectures posted by Stanford University aimed at teaching the basics of computer science.

To create a machine that could think meant that it would have to be able to process and manipulate information. Thus, a computer is basically a thinking machine that processes information. Recent versions of Linux are widely considered the easiest-to-install operating system so far—some people say “a chicken could install Linux”. However, installing any operating system is not recommended for beginners, and so is outside the scope of this book. After you finish this book, you may be ready to go on to a book that discusses booting a LiveCD or even installing an operating system, for example A Neutral Look at Operating Systems/Linux#Live CDs. A computer needs an operating system to start running, like a car needs an engine to start moving. But installing an operating system is not for beginners, like installing a car engine is not for beginners.

If you’re lacking a skill that is listed in the job description, you can always mention that it is something you are currently learning , and emphasize your ability to pick up new skills quickly. While this goes without saying, before you learn any specialized technical skills, at the very least you need a fundamental understanding of what a computer it is and how it works. In some cases, it can be helpful to learn how the Internet works, too. The specific skills you need are highly dependent on your position and your field, but you can familiarize yourself with this list of top computer skills to start out. Also review some of the best skills to include on your resume.

As will users who want to store numerous large programs, like modern games, or videos, which both require a lot of space.
