What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric codes to characters. Each character has a unique number from 0 to 127, making it possible to represent text as numbers for computer processing.

Common Use Cases

  • Data Transmission: Send text data as numeric codes
  • Programming: Work with character codes in code
  • Encryption: Use ASCII codes as part of encryption algorithms
  • Data Analysis: Analyze text patterns using numeric values
  • Protocol Development: Define communication protocols
  • Education: Learn about character encoding

ASCII Code Ranges

  • 0-31: Control characters (non-printable)
  • 32: Space
  • 33-47: Special characters (!, ", #, etc.)
  • 48-57: Digits (0-9)
  • 58-64: Special characters (:, ;, <, =, etc.)
  • 65-90: Uppercase letters (A-Z)
  • 91-96: Special characters ([, \, ], etc.)
  • 97-122: Lowercase letters (a-z)
  • 123-126: Special characters ({, |, }, ~)
  • 127: Delete (control character)

Examples

Text: Hello

ASCII: 72 101 108 108 111

Text: ABC

ASCII: 65 66 67

Text: 123

ASCII: 49 50 51

Important Notes

  • ASCII only covers English characters and basic symbols
  • For international characters, use Unicode (UTF-8, UTF-16)
  • ASCII codes 0-127 are identical in Unicode
  • Extended ASCII (128-255) varies by encoding
  • Modern systems typically use UTF-8 which includes ASCII
