Redundancy coding is a technique used in information theory to add extra data to a message, which helps in detecting and correcting errors during data transmission. By including redundant information, systems can ensure higher reliability and accuracy in communication channels, even in the presence of noise and interference.

Redundancy coding

Information theory is a mathematical framework for quantifying information, primarily focusing on data compression and transmission efficiency. It introduces fundamental concepts such as entropy, which measures the uncertainty in a set of outcomes, and channel capacity, which defines the maximum rate of reliable communication over a noisy channel.

Error detection is a critical process in computing and data transmission that identifies and signals the presence of errors in data. It ensures data integrity and reliability by using algorithms and techniques to detect discrepancies between the received data and what was expected.

Error Detection

Error correction is a process used to detect and correct errors in data transmission or storage, ensuring data integrity and reliability. It employs algorithms and techniques to identify discrepancies and restore the original data without needing retransmission.

Error Correction

Data transmission is the process of sending digital or analog data over a communication medium to one or more devices, ensuring accuracy and integrity during the transfer. It is fundamental to modern communication systems, enabling the exchange of information across networks and supporting various applications from internet browsing to telecommunication services.
