In addition to supplying print, file, or other services, the network operating system has to provide network security. Different businesses and organizations have varying security needs, but all must have some level of data protection. Therefore, the system must offer a range of configurable security levels, from the relatively nonintrusive to the very stringent. Clients Use Workstation Operating Systems Like other computers, client computers on a network need an operating system. However, a client operating system doesn’t need to manage the resources for other computers or manage security for the network.

CHAPTER 2 17 Servers Use Network Operating Systems Because SBS 2011 has to supply services to as many as 75 users, and you’re depending on it to run your business, a high-powered, robust operating system and highly reliable hardware are essential. When your users rely on a server to get their work done and keep your business running, you certainly don’t want frequent failures— you don’t even want to reboot! In addition to supplying print, file, or other services, the network operating system has to provide network security.
