2. Binary Codes - Part C
The chapter discusses various digital coding systems, including Unicode, ISO-10646, and error detection and correction codes such as parity codes, repetition codes, and the Hamming code. It thoroughly evaluates how these systems help in representing characters across multiple languages and ensuring data integrity during transmission. Key examples, including seven-segment displays, further illustrate these coding techniques.

What we have learnt
- Unicode and ISO-10646 provide a comprehensive character representation.
- Error detection and correction codes are essential in ensuring data reliability.
- The Hamming distance is a significant measure in coding theory for error detection and correction.
Key Concepts
- -- Unicode
- A standardized character encoding scheme that assigns a unique number to every character, ensuring a uniform representation across different languages and platforms.
- -- Error Detection and Correction Codes
- Techniques used in digital communication to identify and correct errors in transmitted data, enhancing reliability.
- -- Hamming Code
- A type of error-correcting code that can detect and correct single-bit errors using parity bits to identify the position of errors.
- -- Parity Bit
- An extra bit added to a data stream to ensure that the total number of 1-bits is even (even parity) or odd (odd parity).
