Network Operating Systems

Network operating systems (NOS) typically are used to run computers that act as servers. They providethe capabilities required for network operation. Network operating systems are also designed for clientcomputers and provide functions so the distinction between network operating systems and stand aloneoperating systems is not always obvious. Network operating systems provide the following functions:
  • File and print sharing.
  • Account administration for users.
  • Security.

Functions provided:

Universal Naming Convention (UNC)

A universal naming convention (UNC) is used to allow the use of shared resources without mapping adrive to them. The UNC specifies a path name and has the form:

\\servername\pathname

If I have a Linux server called "linux3" with a folder named "downloads" with a file called "readme.txt"in the folder, the UNC is:

\\linux3\downloads\readme.txt
