Document Summary
Earliest clear recording is from chinese civilization, in 9th century b. c. In europe binary numbers appeared in 17th century credited to leibniz, a theologian and philosopher. Claude shannon, in 1937, proposed a theory of how math could be done w binary code (binary arithmetic) If you have a code which consists of only 2 possible values, it doesn"t matter what you call them (0 1/ High low/ yes no/ on off/ birds pigs etc) 0/1 or 0/1 or 0/1 = 8 possibilities. No, or very little, noise is added by transmission or storage, making message more clear. Can produce perfect copies which had been unheard of in human history. Analog has more than 2 options, creating more noise/mistaken signals. Ease of segmentation (message can be broken up and put back together, makes sending easier) Weather, colours, and sounds all have degrees of intensity.
