Computer Science is the fast-growing field in the World and there are no signs of slowing. Just because this is a relatively new field of study, it should not be scary to learn or thought to be too difficult to understand. Anyone who has ever turned on a phone or surfed the Internet should have a basic understanding of what happens when the mouse is clicked or the screen is touched (and how fast it happens!). How does a simple process convert to 1s and 0s and travel thousands of miles in a blink of the eye? What is an IP address? What do IP/TCP, DNS, HTML, and CSS stand for? How do large movies and thousands of songs all fit onto a hard drive? How can secrets be sent in plain sight? These questions are answered in Computer Science Principles: The Foundational Concepts of Computer Science, plus spreadsheets, photo-editing, web-design (HTML and CSS), learning to code with javascript, and more!
