About ASCII
ASCII (American Standard Code for Information Interchange) is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.
ASCII Character Sets:
- Standard ASCII - Uses 7 bits to represent 128 characters (0-127)
- Extended ASCII - Uses 8 bits to represent 256 characters (0-255), though these extensions vary by system
The ASCII character set includes control characters (0-31), printable characters (32-126), and the Delete character (127). Printable characters include letters, digits, punctuation marks, and various symbols.
Note: Modern systems typically use Unicode (UTF-8) encoding, which is a superset of ASCII, as it supports characters from virtually all written languages.
