Preview: ... r><br>Network Operating Systems<br><br>Operating systems are the interface between individual programs and the user. Through the operating system, the user is able to name files, move them and otherwise manipulate them, and issue commands to the computer as to what the user wants to do. Network operating systems are similar to this, but exist (as the name implies) in the network environment. Thus a network operating system is used to issue commands to shared devices, and to provide a background against which scarce resources are divided among competing users. Ideally, the network operating system is transparent to the user, who is only aware of the ability to share information and resources. An efficient NOS can make the difference between a productive and an unproductive office, and between workers who are difficult to replace when they leave and those who are likely to be familiar with the NOS of choice.<br><br>Despite their importance, network operating systems have faced challenges in the market because of the diverse hardware requirements that they must meet. Because of this, several different operating systems have been developed, some of which run in place of traditional (single-user) operating systems, and some of which run in addition to these systems. OS/2, for example, provides a multi-user environment without requiring a separate operating system. <br><br>NOS development gained widespread acceptance when companies such as Artisoft (which manufactures Lantastic) introduced client software which worked with a variety of servers. This made software manufactured by companies such as Novell (which required special client-side networking software) vulnerable, and Microsoft's Windows 95 quickly became the client software of choice in the market (although not always among analysts) when it was introduced since it can interface with a number of different server systems with complete transparency to the user. This is the same concept used to develop OS/2 Warp Connect. <br><br>Comparison Criteria<br><br>Because of the current state of the market, having 32-bit capability is a requirement in most network environments. The various NOS alternatives need to offer a strong file and print base, since that is how most users access and use the networks. Application services, which includes the ability to run messaging, database, and other server-based applications efficiently in a client/server network is an essential requirement of most modern networks.
