Automating the office – LAN operating systems

Protocols like Ethernet or Token Ring have established low-level links between computers and peripherals in the office. But that's only part of the solution – workers still need to do higher-level tasks such as sending e-mail, exchanging files, and sharing printers.

This need yields a hodge-podge of third party “network operating systems,” including Novell Netware, and built-in solutions like Apple’s AppleTalk. In the 1990s, Internet protocols will replace them all.
