A Brief History of LAN Operating Systems

Networking systems have been available from the earliest days of the microcomputer, the first being proprietary file or disk servers manufactured to control network operations. Novell’s NetWare S-Net was one of the pioneers. A clunky-looking white box powered by a Motorola, Inc., 68000 chip, it was designed as a star topology with a relatively low number of users. From the beginning, S-Net needed an operating system to provide services to the workstations that used CP/M and then DOS. Novell hired a development team to build its first network operating system, which existed as software independent of Novell’s proprietary server. NetWare was the result. Other organizations followed similar routes.
