in full American Standard Code for Information Interchange.
Data-transmission code used to represent both text (letters, numbers, punctuation marks) and noninput device commands (control characters) for electronic exchange and storage.
Standard ASCII uses a string of 7 bit s (binary digits) for each symbol and can thus represent 2 7 = 128 characters. Extended ASCII uses an 8-bit encoding system and can thus represent 2 8 = 256 characters. While ASCII is still found in legacy data, Unicode , with 8-, 16-, and 32-bit versions, has become standard for modern browser s. In particular, the 32-bit version now supports all of the characters in every major language.
