A 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?

The network is using a client-server networking model, where the computers (clients) are connected to a central server (router) which connects to the Internet.

If one computer is upgraded from Windows 10 Professional to Windows Server 2016, the network can now support a domain controller model. Windows Server 2016 includes Active Directory Domain Services (AD DS), which allows for centralized user management, security, and other advanced networking features. With Windows Server 2016, the upgraded computer can function as a domain controller, enabling features such as centralized authentication, policy management, and group management across the network.

The network described uses a client-server networking model. In this model, the five computers running Windows 10 Professional act as clients, and the server is represented by the router that connects the computers to the Internet.

If one computer in the network is upgraded from Windows 10 Professional to Windows Server 2016, the network can now support the peer-to-peer networking model as well. This is because Windows Server 2016 is designed to function as a server operating system that can provide centralized resources and services to other computers on the network. With this upgrade, the upgraded computer running Windows Server 2016 can act as a dedicated server, allowing other computers in the network to connect to it and access shared resources, such as files and printers.

Therefore, with the upgrade to Windows Server 2016, the network can now support both the client-server and peer-to-peer networking models.
