 **Encoding techniques** are methods used to convert data into a specific format for efficient storage, transmission, or processing. These techniques are widely applied in fields such as telecommunications, data storage, and information security to optimize performance and ensure data integrity. \\
-In addition to encoding, **encryption** is a crucial technique used to secure data by converting it into a coded format that is only decipherable with the appropriate key, ensuring privacy and protection against unauthorized access.
