Understanding the ASCII Character Encoding Standard
ASCII (American Standard Code for Information Interchange) is the foundational character encoding standard of modern computer science and telecommunications. Introduced in 1963, ASCII maps 128 specified characters—including numbers (0–9), uppercase and lowercase English alphabet letters (A–Z, a–z), punctuation marks, and system control codes—into integer values from 0 through 127.
Key Decimal Ranges in Standard ASCII
Control Codes (0–31)
Non-printable operational signals, such as Null (0), Line Feed (10), and Carriage Return (13).
Digits & Uppercase (48–90)
Decimal 48 through 57 represent '0'–'9', while 65 through 90 represent uppercase letters 'A'–'Z'.
Lowercase & Symbols (97–127)
Decimal 97 through 122 represent lowercase letters 'a'–'z', with punctuation and Delete (127).
