How Does the Internet Work?

In the space of 30 years the Internet went from a novelty used by engineers to become a part of our lives as essential as transportation. A third of the world's people use it and it has spread to virtually every country on earth. This 3-nighter explores the networks and technologies that work in concert to provide the wide range of services offered on the Internet. The 3-nighter is organized into four fifteen minute videos per hour. Each video is accompanied by a self-exam of ten multiple choice questions. There are no prerequisites, but students should have experience using the Internet and an interest in learning more about the technologies that enable it. Students who pass the 3-nighter will gain a better understanding of how the networks are interconnected, how the Internet is organized and how it operates.

Perhaps the most significant impact though is the relaying and broadcasting of television programming – even if you receive your TV through cable or over-the-air, the chances are that it has been relayed by a satellite along the way.

This “3 Nights And Done” presentation covers the broad topic of satellites in a mathematically light manner concentrating on communications satellites which are in a fixed position in the sky because of their particular orbit (Geostationary). Other types of orbits and uses for satellites will also be touched on.

The process for building and launching a satellite will be discussed followed by how satellites are maintained once in orbit. Those aspects of the payload (or mission) for a satellite that are common to all satellites are discussed at some length ...
