TCP/IP-Ethernet Tower of Babel Breeds Confusion

摘要

CONFUSED ABOUT ETHERNET AND THE TRANSMISSION CONTROL protocol/Internet protocol (TCP/IP) stack and/or suite of protocols? That's not surprising. "This is not an easy subject to talk about. There are so many protocols, and terms have evolved-even the way the word 'Ethernet' has been used," states John Ditter, input/output product specialist with Germantown, Wis.-based automation components vendor Wago Corp. (www.wago.com). "To most people, the word 'Ethernet' includes the TCP/IP stack. But these are different things," adds Dick Caro, principal of network consultant CMC Associates (www.cmc.us), Acton, Mass.
