Information Theory and Practice

Information Theory is a mathematical framework for understanding how data is measured, transmitted, and compressed. It explores concepts like "information content" and the limits of efficient communication, ensuring messages are sent accurately over noisy channels. In practice, it underpins technologies such as data compression (like ZIP files), error correction in digital communications, and cryptography. Ultimately, it helps optimize and secure how information is stored and shared in our digital world, making communication faster, more reliable, and efficient.
