Paper 1
A collection of characters and their corresponding codes that a computer uses to represent text.
Revise: Binary Character RepresentationTo represent text, each character is assigned a character code — a unique binary value within the character set being used. The computer stores these codes rather than storing the letters themselves as readable text.
When explaining character representation, state that each character is assigned a unique binary code within the character set being used.
Define a character set as both a collection of characters and the unique codes assigned to them.
When comparing character sets, link the range of supported characters to a practical consequence, such as supporting multilingual text.
