A number system defines how we represent numbers. It defines which digits we can use, and what value each position (place value) in a number has.
The binary number system is the Base 2 Number System. It is a number system that only uses 2 digits (0 and 1).
Bit means "binary digit". A bit is a single digit in a binary number. A bit can either be 0 or 1.
ASCII is the standard protocol for encoding text information as bits. The ASCII table assigns a unique binary number to every text character.
The RGB encoding scheme allows us to encode colors such as numeric data. It defines the amount of Red, Green, and Blue light in a pixel.
