File Server

File Server as a powerful component of LAN

The file server is a powerful computer which runs a special software to act as a file server. As the name suggests, it serves to networked computers which share and use these files. The files can be programs, text or data. The file server is a completely enclosed logical structure, which is secure against accidental or malicious abuse as it can be accessed only through Network Operating System (NOS).

The activity of each file server can be monitored from the file server's screen. The system supervisor monitors and control operation of each individual network through the file server and uses it to control the print spooling, send/broadcast messages and perform many other system functions. The file server has a large volume of memory which is used for caching directories, files and directory hashing. File servers also support backup facilities, print serving and so on.

Novell Net Ware, for example, requires on a workstation to log on to a file server to enter the LAN. Under Novell Net Ware, specifically designed machines are converted to file servers. Under the PC network Program, any workstation can perform the function of file serving on any files that have been designated as public.

A file server is a resource that should be available to all workstations. If the file server is forced to operate as a workstation at the same time, it then must divide its processing time and memory between two tasks, with the performance of both suffering.
