1. History of Binary
A Presentation By: Yasmine Dabbah, Daniel Mashal, Gracee Kim, and Chance Ward

2. Quick Review The simplest of all positional number systems
The base (‘radix’) is 2
Means only the digits 0 or 1 can appear in this system
Convert the decimal number 3 into a binary number = 112
Internal structure of most computer systems

3. History of the Binary System
Mainly developed by Gottfried Leibniz in mid 17th century
Explained significance of 0 and 1
Originally used to reason through binary propositions
Inspired Boolean Algebra

4. Applications of Binary
Bagua
Yin/Yang
Braille
Raised/Not Raised
CDs
Hill/Valley

5. Computers and Binary
Bit: smallest unit of information storable on the computer
Consists of either 1 or 0 (YES or NO)
Bits group together to make bytes (coined by Werner Buchholz, 1956)
One byte usually = 8 bits
Other bit combinations:
‘Nibble’
Kilobyte (KB)
Megabyte (MB)
Gigabyte (GB): a typical flashdrive has anywhere from 8-64 GB

7. Computers and Binary - Color
Hexadecimals (a power of 2) simplify the string of bits
2 hexadecimals = 8 binary bits = 1 byte
Colors (HTML) are hex-triplets
RGB color system: colors made by mixing red, green, and blue
Black: , white: FFFFFF
Pantone’s Color of the Year 2015, Marsala:

8. How do computers read binary code?
Transistors turn binary codes into tasks for computers
IBM 608 introduced and marketed in 1955 (the first fully transistorized computer!)
Could ONLY calculate (though at rapid speed)

9. ASCII Coding American Standard Code for Information Interchange
Represents text in computers and other communication devices that use text
Most commonly used system on World Wide Web
Surpassed by UFT-8, which includes ASCII as a subset, in 2007

10. ASCII Coding Uses 7-bit binary codes
Each letter or symbol is assigned decimal number 0-127
First 32 characters are ‘nonprintable’
Used as commands (i.e. shift, backspace)
Remaining characters are ‘printable’

11. 41 The decimal number assigned to the character ‘A’ is 65.
What would be the hexadecimal number? 41

14. THE END
“There are only 10 types of people in this world: those who understand binary and those who don’t.”
