About ASCII Character Encoding

The ASCII table is one of the most fundamental references in computing. Originally developed in the 1960s, ASCII maps 128 characters to numeric values (0-127). The first 32 codes (0-31) plus code 127 are control characters used for device control and text formatting. Codes 32-126 are printable characters that include uppercase and lowercase letters, digits 0-9, punctuation marks, and special symbols. ASCII remains the backbone of text processing, and its 7-bit character set is a subset of virtually every modern encoding standard including UTF-8.

Frequently Asked Questions

What is ASCII?▾

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric values (0-127) to letters, digits, punctuation marks, and control characters. It's the foundation of modern text encoding.

What is the difference between printable and control characters?▾

Control characters (0-31 and 127) are non-printable characters used for text formatting and device control (e.g., tab, newline, carriage return). Printable characters (32-126) include letters, digits, punctuation, and the space character.

How do I use ASCII codes in programming?▾

In most programming languages, you can convert between characters and ASCII codes. For example, in JavaScript: String.fromCharCode(65) returns "A", and "A".charCodeAt(0) returns 65.
