RS Code

RS Code, or Reed-Solomon code, is a type of error-correcting code used in digital communications and storage. It adds extra data, called redundancy, to a message, allowing the system to detect and correct errors that may occur during transmission or storage. Imagine it like a spell-check for data: if some parts get damaged or lost, the RS Code can often restore the original information without needing a retransmission. This makes digital systems more reliable, ensuring data integrity in environments like CDs, DVDs, QR codes, and deep-space communications.
