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.

Term: Unicode
Definition: A standardized character encoding scheme that assigns a unique number to every character, ensuring a uniform representation across different languages and platforms.
Term: Error Detection and Correction Codes
Definition: Techniques used in digital communication to identify and correct errors in transmitted data, enhancing reliability.
Term: Hamming Code
Definition: A type of error-correcting code that can detect and correct single-bit errors using parity bits to identify the position of errors.
Term: Parity Bit
Definition: 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).
