About ASCII Encoding

Standard ASCII

American Standard Code for Information Interchange (ASCII) uses 7 bits to represent 128 characters including control characters, digits, letters, and punctuation.

Extended ASCII

Extended ASCII uses 8 bits (0-255) to include additional characters, symbols, and accented letters. Different systems may use different extended character sets.

Control Characters

ASCII codes 0-31 represent control characters like NULL, TAB, NEWLINE, and CARRIAGE RETURN used for text formatting and device control.

ASCII Applications

ASCII is fundamental to text files, programming languages, network protocols, and legacy systems. It forms the basis of modern character encoding standards.
