Binary system
Binary system consists of two numbers. These numbers are 0 and 1. Electrical processors work on the principle that 1 represents availability of a signal and 0 represents absence of it.
With 8 combinations of 0 and 1, it is possible to count all the way to 255. Starting number is 0.
If higher values are needed, then more than 8 combinations are needed.
Modern computers have either 32 or 64 bits, allowing them to work with larger numbers.
Bits can be translated to RGB values. RGB stands for red, green and blue. With only 256 combinations of red, green and blue, it is possible to represent millions of colors.
Not only colors can be represented by numbers, but sounds can be represented by numbers too.
Better sounding audio requires more bits.
A human does not deal well with binary data, a human operates well with 0 to 9 numbers, so it is needed to have a process that transforms our numbers to numbers that a computer understands.
Numbers that are represented by numbers 0 to 9 are called decimal numbers, and the numbers which are represented by 0 and 1 only are called binary numbers.
