Binary code
From Wikipedia, the free encyclopedia
The term binary code can mean several different things:
- There are a variety of different methods of coding numbers or symbols into strings of, including fixed-length binary numbers, prefix codes such as Huffman code, and other arithmetic coding.
- Made up of only zeros and ones, and used in computers to stand for letters and digits.
For example, computers using western languages often use 8-bit binary codes for characters. The ISO 8859-1 character code uses 8 bits for one letter e.g. "R" is "01010010" and "b" is "01100010"; the block of 8 bits is called a byte. The ASCII code uses 7 bits to represent 128 characters (0–127).
