Code, Second Edition first establishes what numeric codes are, and then walks you one "baby step" at a time through the basic theoretical and applied concepts required to construct a simple computer. For more effective learning, Petzold describes rudimentary digital technology, while also revealing how today's world of media and connectivity was built through the pervasive use of numeric codes.
