The purpose of this paper is to present the differences in hardware, installation, operation cost and performance of three methods of connecting computing hardware in an integrated network. Two of those methods, Ethernet and Token-Ring, have been in use and in competition with each other for a number of years. A third method, Asynchronous Transfer Mode (ATM), is viewed by many as the next generation of computer networking. The two earlier protocols, Ethernet and Token-Ring, are currently undergoing two simultaneous evolutions. Those protocols are being revised to include both l00Mbit (100 Megabit, 100 million bits per second) and 1,000Mbit (Gigabit, one billion bit per second) versions. l00Mbit systems are already being placed in service, albeit in somewhat limited applications while Gigabit systems are essentially restricted to lab testing at this time. The author would be remiss if these systems were not discussed in this paper.
