network consists of five computers, all running Windows 10 Professional. All the computers are connected to a switch, which is connected to a router, which is connected to the Internet. Which networking model does the network use, suppose one computer is upgraded from Windows 10 Professional to Windows Server 2016. Which networking model can the network now support that it could not support without the upgrade? what topology is used

The networking model used in this network scenario is a client-server model. Each computer running Windows 10 Professional functions as a client, connecting to the server for sharing resources and accessing services.

If one computer is upgraded from Windows 10 Professional to Windows Server 2016, the network can now support a domain-based networking model. With Windows Server 2016, the upgraded computer can act as a domain controller, allowing centralized management of network resources, user authentication, and other domain-specific functionalities.

The topology used in this network scenario is likely a star topology. In a star topology, all computers are connected to a central switch, forming a star-like structure. This switch is then connected to the router, which provides access to the Internet.

Based on the provided information, the network is using a client-server networking model. This is because the computers running Windows 10 Professional are acting as clients, while the upgraded computer running Windows Server 2016 can act as a server.

By upgrading one computer to Windows Server 2016, the network can now support a domain-based networking model. This means that the Windows Server 2016 computer can now act as a domain controller and manage user accounts, security policies, and network resources for all the computers in the network. This functionality is not available with Windows 10 Professional alone.

Regarding the network topology, it is not explicitly mentioned in the given information. However, based on the provided description of the network components (computers connected to a switch, connected to a router, connected to the Internet), it can be inferred that the network is using a star topology. In a star topology, each computer is connected to a central switch, which is then connected to a router for internet connectivity.
