Understanding the Trinity Network

At long lost, I think I am finally understanding how an institution, such as a college campus, gets a connection to the Internet and maintains its servers. I have never known much about the hardware behind working, high-speed Internet. It was very cool to take a look behind the scenes and have Jared Pack explain the connection to us. I was surprised by a number of things. For example, I couldn't have guessed that data was backed up on cassette tapes which often are seen as equipment of the past. I feel less ignorant knowing at least a bit about how our computer's precious connection to the online world must go through multiple sources before rendering the results we want.
