Full Form of ASCII Code
ASCII stands for American Standard Code for Information Interchange. It is a character encoding standard used for representing text in computers and other devices that use text.
Key Features of ASCII:
- Character Representation: ASCII uses a 7-bit binary number to represent characters, allowing for 128 possible symbols.
- Standard Characters: The first 32 codes (0-31) are control characters (non-printing), used for text formatting and control purposes.
- Printable Characters: Codes 32-126 represent printable characters, including:
- Uppercase Letters: A-Z (65-90)
- Lowercase Letters: a-z (97-122)
- Digits: 0-9 (48-57)
- Special Symbols: Such as punctuation marks and operator symbols.
Uses of ASCII:
- Text Files: ASCII is commonly used in text files and programming languages.
- Data Transmission: It is widely used in data communication protocols.
- Compatibility: ASCII ensures compatibility across different computer systems and devices.
Extended ASCII:
- 8-bit Version: While standard ASCII uses 7 bits, extended ASCII uses 8 bits, allowing for 256 characters.
- Additional Characters: Extended ASCII includes additional symbols and characters like accented letters and graphical symbols.
Conclusion
ASCII remains a foundational technology in computing, facilitating the exchange of text-based data across various platforms and devices. Understanding ASCII is essential for anyone involved in computer science, programming, or data communication.
