Week one, the lecture explained some words, for example, What is communication, What is Technology. From Wikipedia, Communication is a process of transferring information from one entity to another. Communication processes are sign-mediated interactions between at least two agents which share a repertoire of signs and semiotic rules. Communication is commonly defined as "the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs". Technology is a broad concept that deals with human as well as other animal species' usage and knowledge of tools andcrafts, and how it affects a species' ability to control and adapt to its environment. In our lecture, Marshall Mcluhan argues that technologies are extensions of human body ... a tool is an extension of the hand; a wheel is an extension of the leg; and a book is an extension of the eye.
As we know, lots of inventions make a revolution in filmdom, though most of the inventions are not worked for filmdom in the beginning. Following the technology, from silent films to sound film, from black-and-white photography to color film and Cinema Scope, the filmdom developed enormous.
New Communication Technologies are also introduced in our lecture. I think the list of the New Communication Technologies is better to explain.
