The ASCII (American Standard Code for Information Interchange), also known as US-ASCII, is a character encoding standard developed in the 1960s. It was tailored primarily for the English language and employs a 7-bit encoding scheme, which covers 128 characters. This encoding standard includes 33 non-printable control characters and 95 printable ones. Historically, ASCII has played a pivotal role in shaping subsequent character encoding standards, such as ISO 8859-1 and UTF-8.
