How ASCII Encoding Works
ASCII assigns numeric values (0-127) to characters for computer representation.
Standard ASCII covers English letters, digits, punctuation and control codes.
Each character converts to its decimal ASCII value.
Extended ASCII (128-255) adds additional characters, though not a formal part of ASCII.
Frequently Asked Questions
Q.What is ASCII?
A. ASCII (American Standard Code for Information Interchange) assigns numeric values (0-127) to characters. For example, 'A' is 65.
Q.What characters are supported?
A. Standard ASCII covers characters 0-127 (English letters, numbers, punctuation). Extended ASCII (128-255) is also supported in many contexts.
Q.How does ASCII encoding work?
A. Each character is converted to its ASCII decimal value. Multiple values are separated by spaces in the encoded output.
Q.Is ASCII encoding secure?
A. No — ASCII is a character-encoding standard, not encryption. For data security use proper cryptographic methods.
