ABSTRACT

By the same token, a computer has two “fi ngers” to count on, so to speak, or two states by which to keep track of numbers-“on” and “off.” At the heart of every computer is a complex arrangement of microscopic switches that do everything from carrying out instructions to keeping track of numerical and graphical data. Each of these switches can be turned on or off individually. By arranging them in groups called bytes, each group can represent a piece of data that, taken collectively, paints an entire picture.
