About ASCII Encoding

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numerical values to letters, digits, punctuation marks, and control characters.

The standard ASCII character set uses 7 bits, providing 128 character codes (0-127). Extended ASCII uses 8 bits, allowing for 256 character codes (0-255).

Common ASCII ranges:

  • 0-31: Control characters
  • 32: Space
  • 33-47: Punctuation
  • 48-57: Digits 0-9
  • 65-90: Uppercase A-Z
  • 97-122: Lowercase a-z
