 What is binary?  A Word Definition From the Webopedia Computer Dictionary 
  Computers are based on the binary numbering system, which consists of just two unique numbers, 0 and 1. 
  All operations that are possible in the decimal system (addition, subtraction, multiplication, division) are equally possible in the binary system. 
  This is Chapter 1 of Randall Hyde's book, "Art of Assembly Language." It describes the binary and hexadecimal numbering systems, binary data organization (bits, nibbles, bytes, words, and double words), signed and unsigned numbering systems, arithmetic, logical, shift, and rotate operations on binary values, bit fields and packed data, and the ASCII character set.
