Character Representation Flashcards

A defined list of characters that a computer can recognise and represent, each mapped to a unique binary code.

A character set that uses 7 bits to represent 128 characters, including English letters, digits, and some symbols.

An 8-bit character set that can represent 256 characters, including additional symbols and characters for other languages.

A character set designed to represent characters from all languages, using multiple bytes per character.

Characters are stored as binary numbers, with each character assigned a unique binary code in the character set.

The number of characters that can be represented is 2^n, where n is the number of bits used per character.

Efficient for representing English text as it uses fewer bits per character compared to Unicode.

Can represent a much wider range of characters, making it suitable for global use.

Computers process data in binary, so characters must be converted into binary codes for storage and processing.

ASCII uses fewer bits and is limited to 128 or 256 characters, while Unicode uses multiple bytes and can represent thousands of characters.
