A way of representing non-numerical data.
Commonly Used Encodings
ASCII
Abbreviation for American Standard Code for Information Interchange. Uses 7 bits for letter representation and a parity bit (MSB). Can represent latin alphabet, digits, punctuations, and control characters.
Major limitation in ASCII is it can’t support multiple languages.
Unicode
Uses 32 bits. Supports multiple languages and emojis. Characters are presented by code points. A code point is a integer (in base 16).
