CBSE 10th Class Unit 1 -Encoding Schemes

 Encoding Schemes

Encoding schemes are used to represent characters (letters, numbers, symbols) as binary numbers.

1. ASCII (American Standard Code for Information Interchange):
• Uses 7 bits to represent 128 characters.
• Includes uppercase and lowercase letters, numbers, punctuation marks, and control characters.
2. ISCII (Indian Standard Code for Information Interchange):
• An 8-bit character encoding standard for Indian languages.
• Supports a wider range of characters than ASCII.
3. Unicode:
• A universal character encoding standard that supports a vast number of characters from different languages.
• Common encodings include UTF-8, UTF-16, and UTF-32.
• UTF-8 is the most widely used encoding, as it is backward compatible with ASCII and can represent characters using a variable number of bytes.
