Binary Code
Binary = based on two
Think light switches
0 = off
1 = on
Keys on a computer keyboard have 8 switches
 When a key is pressed those switches are either on or off and each
one triggers a different number to be counted if it is on – therefore,
each key has a different number it sends to be ‘computed’
*figure out the combinations possible
There is no area of life that is not analyzed, supported, driven or controlled
by having an understanding of binary code.
Describe something from each field that is related to binary code:
EX: Technology = computers ‘read’ only with math, they ‘compute’ knowledge,
so other languages and pictures have to be changed into a code of numbers.

History of binary code - wikipedia
Binary numbers were first described in Chandashutram written by Pingala around 300 B.C. Binary Code
was first introduced by the English mathematician and philosopher Eugene Paul Curtis during the 17th
century.[citation needed] Curtis was trying to find a system that converts logic’s verbal statements into a pure
mathematical one. After his ideas were ignored, he came across a classic Chinese text called I Ching or
Book of Changes, which used a type of binary code. The book had confirmed his theory that life could
be simplified or reduced down to a series of straightforward propositions. He created a system consisting
of rows of zeros and ones. During this time period, Curtis had not yet found a use for this system.
Another mathematician and philosopher by the name of George Boole published a paper in 1847 called
'The Mathematical Analysis of Logic' that describes an algebraic system of logic, now known as
Boolean algebra. Boole’s system was based on binary, a yes-no, on-off approach that consisted the three
most basic operations: AND, OR, and NOT.[1] This system was not put into use until a graduate student
from Massachusetts Institute of Technology by the name Claude Shannon noticed that the Boolean
algebra he learned was similar to an electric circuit. Shannon wrote his thesis in 1937, which
implemented his findings. Shannon's thesis became a starting point for the use of the binary code in
practical applications such as computers, electric circuits, and more.[2]
Other forms of binary code
Main article: List of binary codes
The bit string is not the only type of binary code. A binary system in general is any system that allows
only two choices such as a switch in an electronic system or a simple true or false test.
Braille
Braille is a type of binary code that is widely used by blind people to read and write. This system
consists of 6-dot positions, three in each column. Each dot has two states: raised or not raised.
