The Physical Side of the Internet
Cheryl A. Casey and Mary Ann Allison
More than just air
For many of us, the Internet is a sort of given. It’s simply there, like our homes, the grocery store, and the dentist’s office. We go to these places whenever we want or need. It’s the same with cyberspace—we just go. In my small town, I can even use my laptop to go online while sitting in the pavilion at the village green. Anyone in downtown Waterbury, Vermont, has access to a free wireless connection provided by the town.
The places—including cyber places—that we take for granted don’t simply appear by magic. They take a good deal of effort to build and maintain.
For many of us, the Internet “is” what appears on our screens. Most of us depend on this information for school, work, entertainment, and connecting with our friends and families.
Physically, though, the Internet is composed of many more than 9 billion computers of various types and the wires, cables, and satellites that connect them.
Sometimes it takes a disaster—an earthquake, a monsoon, or a war—to make it clear that the Internet relies on equipment and cables to deliver. But even something as small as a squirrel can stop the information flow by gnawing through a wire.
