When mainframe and minicomputers provided the backbone of business computing, there were essentially networked environments in the sense that "dumb" terminals shared access to a single processor (the minicomputer or mainframe), printer (or printers) and other peripheral devices. Files could be shared among users because they were stored on the same machine. Electrical and operational connections were available in common and shared applications, and implementation of new hardware, software and users was a simple task so long as a single vendor was used. With the proliferation of microcomputers in the business environment, information became distributed, located on the various hard drives attached to personal computers in an office, and difficult for other users to access. Today, network systems which connect disparate hardware, software and peripherals are commonplace, but the communication program which makes using these systems has not kept up with the demand for such environments, although a number of companies are now participating in the field. This research considers two of the most popular network operating systems (NOS), NetWare by Novell and Windows NT by Microsoft, and considers which is appropriate for business applications.
Network Operating Systems
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...
