ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numbers 0-127 to letters, digits, punctuation, and control characters. For example, 'A' is 65, 'a' is 97, '0' is 48. ASCII uses 7 bits per character, which fits in one byte (8 bits). It was developed in the 1960s and remains the foundation of text encoding in computers.

What's the difference between ASCII and Unicode?

ASCII has only 128 characters (0-127), covering basic English text and control characters. Unicode is a much larger system with over 143,000 characters, covering all world languages, emojis, and symbols. UTF-8, a Unicode encoding, is backward-compatible with ASCII: the first 128 UTF-8 characters are identical to ASCII. Modern applications primarily use Unicode (UTF-8) while maintaining ASCII compatibility.

What are ASCII control characters?

ASCII codes 0-31 and 127 are non-printable control characters. Common ones include: 0 (NULL), 9 (Tab), 10 (Line Feed/LF), 13 (Carriage Return/CR), 27 (Escape), 32 (Space), 127 (Delete). These were originally designed to control teletype machines and printers. Some like newline (LF) and tab are still essential in modern text files.
