Binary Representation of Data
In order to work with data, the data must be represented inside the computer. Digital
computers represent data by means of an easily identified symbol called a digit.
Numbering Systems
Each number system has a base also called a Radix. A decimal number system is a
system of base 10; binary is a system of base 2; octal is a system of base 8; and
hexadecimal is a system of base 16. What are these varying bases? The answer lies in
what happens when we count up to the maximum number that the numbering system
allows. In base 10, we can count from 0 to 9, that is,10 digits.
