What is Information? A few bits about it.

When we look at the networks, phones, computers and other data-driven devices that surround us, it is easy to be convinced that information plays a central role in our everyday lives. However, many of us have never thought about what information is, how it moves from place to place, and how it can be represented and stored efficiently. Fortunately for our devices, there is a branch of engineering and mathematics called Information Theory dedicated to understanding issues exactly like these. Just as Newton's laws describe the nature of classical mechanics in physics, Information Theory has provided us with a set of mathematical principles that govern the flow and utility of information. In this talk, we'll explore the basic concepts of information transmission and storage, and reveal how these principles have guided and enabled virtually all of our computing, communication and storage technologies.
