• The term network operating system is used to refer to two rather different concepts:
• in a peer-to-peer network operating system users are allowed to share resources and files located on their computers and access shared resources from others. This system is not based with having a file server or centralized management source. A peer-to-peer network sets all connected computers equal; they all share the same abilities to use resources available on the network.
• What are the types of network operating system?

  Peer-to-peer, client-server
• The advantages include: Peer to peer

  • Ease of setup
  • Less hardware needed, no server need be acquired t
• The disadvantages include: Peer to peer

  • No central location for storage
  • Less security than the client-server model
• Operating systems can be based on a client-server model (architecture) in which a server enables multiple clients to share resources. Client-server network operating systems allow networks to centralize functions and applications in one or more dedicated file servers. The server is the center of the system, allowing access to resources and instituting security.
• Client Server Network

  File and print servers

  Data for printing

  Login request

  User files
• The advantages include: Client Server Network

  • Centralized servers are more stable.
  • Security is provided through the server.
  • New technology and hardware can be easily integrated into the system.
  • Hardware and the operating system can be specialized, with a focus on performance.
  • Servers are able to be accessed remotely from different locations and types of systems.
• The disadvantages include: Client server network

  • Buying and running a server raises costs.
  • Dependence on a central location for operation.
  • Requires regular maintenance and updates.
