The 7-Layer Vocabulary of Modern Internetworking.
This is the second movie in our "Internet" series, and it explains the popular vocabulary by which modern Internetworks are described.
Before the Internet became popular, networks were proprietary and couldn't communicate with one another. In 1977, the International Standards Organization published the vocabulary that has been used ever since to describe interoperable network components. You'll want to know that vocabulary as you purchase and configure your network equipment. This 12-minute video explains how and why that vocabulary developed, and how modern networks use an interchangeable, "layered" approach to guide messages into the deep inner workings of your computer's many software applications.
This movie continues building an excellent foundation and
introduction for anybody that wants to know how their Local Area Network
works, and for people studying to learn the most basic concepts needed
to pass any of these certification exams:
