      Dan Gookin

      Mad Genius

      Dan Gookin is the author of more than 120 titles. He has been writing about technology for over 20 years.

      Dan combines his love of writing with his gizmo fascination to create books that are informative, entertaining, and not boring. Because his 120 titles have 12 million copies in print that have been translated into over 30 languages, Dan can attest that his method of crafting computer tomes seems to work.

      Perhaps his most famous title is the original DOS For Dummies, published in 1991. It became the world's fastest-selling computer book, at one time moving more copies per week than the New York Times #1 bestseller (though as a reference, it could not be listed on the NYT Bestseller list). From that book spawned the entire line of For Dummies books, which remains a publishing phenomena to this day.

      Dan's most popular titles include PCs For Dummies, Word For Dummies, Laptops For Dummies, and Droid X For Dummies. He also maintains the vast and helpful website,

      Dan holds a degree in communications/visual arts from the University of California, San Diego. Presently, he lives in the Pacific Northwest, where he enjoys spending time with his sons playing video games inside while they watch the gentle woods of Idaho.

In this course I explain what the components and peripherals are, and how to add or remove them, in a safe, sane and effective manner. It's something you can do yourself, and I'm eager to show you how. Now it's time to get started Working with Computer Components and Peripherals.
