Ascii

overview

Summary

ASCII (American Standard Code for Information Interchange) is a 7-bit character encoding standard that maps 128 numeric codes to common characters used in English-language text, including letters, digits, punctuation, and control codes. It underpins early computing and many modern text protocols, and remains the foundation for Unicode’s first 128 code points. Understanding ASCII helps explain text storage, data exchange, line endings, and how bytes map to characters.
