The Language of Computers

Whoa! You may be saying to yourself, “This sounds like we're ramping up to a discussion full of techno-speak.” Don't worry, I'll keep things in honest-to-goodness English.

Computers read, write, and communicate to each other using binary, which has only two values: zero and 1, as illustrated in Figure 1.1, just like a light switch. Your computer stores files and programs as long strings of binary data—and the music on an audio compact disc is also recorded in binary (it's the job of an audio CD player to read the digital information on a disc and convert it back to an audio signal).
