Network Operating Systems

Just as operating systems control the workings of a PC, such as its use of memory, saving files to disk, running software etc, a network needs software to control its operation. The network operating system (NOS) running on a file server does that job.

A NOS typically handles tasks such as:

• authenticating users as they log in
• allocating resources to users (e.g. home directories, access to shared files and equipment)
• maintaining smooth communications across the network
• running software such as virus scanners to protect users’ files
• controlling access to the internet
• logging network activity and maintaining security
• backing up users’ data
