ABSTRACT

Now that we have a way to describe a raw data item (bit, byte, word, etc.) we can discuss how di¨erent types of information are represented inside a computer system.  e native data type is, of course, raw logical (binary) data, in which true and false are represented as 1 and 0. Ultimately, all computations are carried out at this level. Even addition is realized as a sequence of logical operations. We will cover logical data in more depth when we study logical operations and instructions.
