Text data interchange among computers relies on a character encoding that assigns a unique numeric value to each character so different systems interpret the text the same way. ASCII is the widely used standard for this purpose. It uses seven bits to represent 128 characters, including the basic English letters, digits, punctuation, and several control codes. This compact, universal set made early computer networks and software interoperable, and ASCII remains the baseline for most text processing today. Modern encodings like UTF-8 preserve ASCII’s values for the first 128 characters, ensuring backward compatibility while allowing a much larger repertoire of characters. The other codes mentioned aren’t designed as general-purpose text encodings for computers: Gray code is used for position encoding in electronics, Baudot is an old teleprinter code with a limited character set, and Morse is a signaling code for manual communication rather than a binary character set for data interchange.
