Understanding Computers, Smartphones and the Internet

Most introductory books about computers are long, detailed technical books such as those used in a computer science course or else tutorials that provide instructions on how to operate a computer with little description of what happens inside the machine.

This book fits in the large gap between these two extremes. It is for people who would like to understand how computers work, without having to learn a lot of technical details. Only the most important things about computers are covered. There is no math except some simple arithmetic. The only prerequisite is knowing how to use a web browser.

As an alternative or adjunct to reading the book, you can watch a series of short videos by going to youtube.com and searching for "Understanding Computers, Smartphones and the Internet".

Only current day technology is covered. People who are interested in learning about how computers evolved from the earliest machines can read the companion book "A Concise History of Computers, Smartphones and the Internet".

While originally intended for people who are not in the computer field, this book is also useful for those taking a coding course or an introductory computer science course. Even people already in the computer field will find things of interest in this book.
