Fun Fact
The word "ASCII" stands for American Standard Code for Information Interchange. Despite its origin, ASCII became a foundational global standard and paved the way for modern encoding systems like UTF-8, which still preserves ASCII compatibility for the first 128 characters.
Historical Context
ASCII was standardized in 1963 to unify character encoding across computing systems. Before its adoption, incompatible encoding schemes made data exchange difficult. ASCII defined 128 characters, including control codes and printable symbols, using 7-bit binary values. Its simplicity and interoperability made it foundational to early networking protocols, programming languages, and operating systems - and its legacy continues in modern digital communication.
