Lecture 2
In Professor Rocha's lecture: "The Nature of Information", he explains how signs are used in several ways. There are three types of signs which include: icons, indices, and symbols. According to Claude Shannon, information is defined as "the mathematical theory of communication". Information ,according to our Professor, is either Analog or Digital. The difference between them is that analog uses the "Binary System" while digital uses numerical digits. An example of this would be vinyl records (Analog) and Compact discs (Digital).
I look forward in learning about both systems.

Please note that Shannon did not define information as a mathematical theory of communication, rather it was the name of the paper in which he defined the concept of information for the first time.
Also, you seem to be a little confused between digital and analog systems.I will try to clarify a bit here-analog measurement is motivated by a cause and action relation and usually involves measurement of a palpable quantity such as pressure,temperature etc.
