Systems electronic information
James Waddell · The Bovine Practitioner · 1998
The Internet is a loosely organized and as yet unregulated network of computers. It stretches across the entire world, knowing no political or geographic boundaries. The physical connections are usually high speed, dedicated telephone lines. They may be old-fashioned copper wires, modern fiber optics, microwave or even satellite lines. There is much redundancy in the connections and the routing of information occurs almostrandomly. A computer in Minneapolis may connect to one in California by way of Denver one day and Washington, D. C. the next. No one person or even organization knows exactly how the Internet works. Local system administrators know how their own part of the network operates and what other remote systems they are connected to.
