4. Network

   • A Network Operating System runs on a server and provides the server the capability to manage data, users, groups, security, applications, and other networking functions.
     • Advantages: the stability of its server systems / the server-level security / the ease of integrating new technologies / You can access servers from different locations and from other systems
     • Disadvantages: high cost of implementation / maintenance and regular updates

5. Real Time

   • The response of these operating systems is under some time constraints, if not respected is considered that the system has failed
