A diagram from Bob Metcalfe's original memo explaining how Ethernet works. (Credit: Palo Alto Research Center) Most people probably associate Ethernet with a simple colored cable cinched with phone-like jacks. But, Ethernet is so much more. It is the foundation for global Internet access and undoubtedly the world's most used connectivity technology. In the annuals of techdom, Ethernet is a very big deal. "Ethernet ranks highly among those technologies that impact day-to-day life on a global basis," IEEE Standards Association writes on its Web site. "Data center networks, PCs, laptops, tablets, smartphones, and now the smart grid, smart meters, personal medical devices, the Internet of Things, connected cars, and more -- Ethernet touches them all in one way or another." And, it was 40 years ago today that inventor Bob Metcalfe passed around a memo explaining just how Ethernet would work -- connecting multiple computers to one another to exchange messages over increasingly busy networks.
