50 years ago Ethernet was invented by The Xerox Palo Alto Research Center in California. Xerox Parc "has spawned many pioneering computer technologies including the Alto—the first personal computer to use a graphical user interface—and the first laser printer. The PARC facility also is known for the invention of Ethernet, a networking technology that allows high-speed data transmission over coaxial cables. Ethernet has become the standard wired local area network around the world, and it is widely used in businesses and homes." I think you probably use this in your home to connect the Internet to your home's wireless router. Any other uses you can think of?
