Computers contain millions of transistors—microscopic electronic switches that turn on and off millions of times a second to create the computer experience you're having right now. To process the words, images and sounds we use every day, computers and other devices (such as CD players) transform these communications into a simple code that uses the numerals 0 and 1 to represent the on and off states of a transistor. This language of 0s and 1s is known as digital information. As simple as this language may seem, it is extremely versatile and has played a major
role in the greatest technological revolution the world has ever seen.
