Number Systems
To talk about binary data, we must first talk about number systems
The decimal number system (base 10) you should be familiar with!
- A digit in base 10 ranges from 0 to 9.
- A digit in base 2 ranges from 0 to 1 (binary number system). A digit in base 2 is also called a ‘bit’.
- A digit in base R can range from 0 to R-1
- A digit in Base 16 can range from 0 to 16-1 (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F). Use letters A-F to represent values 10 to 15. Base 16 is also called Hexadecimal or just ‘Hex’.
