2.1.2 Windows Server Facts This lesson covers Windows Network Models. Windows Network Models A Windows system can fulfill different roles on a network depending upon how the system and network are deployed. The following table describes three standard network models that are common with Windows systems: Model Description Stand- In the stand-alone model: alone Each host functions independently. Communication takes place using a commonly available public network, such as the internet. The hosts are not connected by a local area network. Workgroup The workgroup model is based on peer-to-peer networking. In the workgroup model: None of the hosts in a workgroup have a specific role. All hosts can function as both workstation and server. All hosts in a workgroup can both provide network services and consume network services. The hosts are linked together by some type of local network connection. Hosts in the same workgroup can access shared resources on other hosts. Drawbacks of the workgroup model are: Lack of scalability. Lack of centralized configuration control. Lack of centralized authentication. Lack of centrally applied security settings. Complex data backup process. Client- In the client-server model, each host has a specific role in the network: server  Model Description Servers provide file storage, authentication, email, and printing. A server may even be configured as a hypervisor, which allows the server to run multiple virtual machines. Virtual machines can be used as single-purpose servers, such as hosting enterprise applications that might be incompatible with other enterprise applications. Clients request services from servers. The client-server model is known as domain networking in a Windows environment. Key domain networking facts include the following: Domain networking uses security principles, which are entities such as users and computers. A Windows domain is a collection of security principles that share a central authentication database called Active Directory. The Active Directory database is located on one or more servers in the domain. Domains are much more efficient and scalable than workgroups due to a centralized management structure and function. Drawbacks of the client-server model include the following: Increased implementation cost due to specialized hardware and software requirements. Increased planning time required for implementation. Increased implementation complexity. Increased knowledge required to manage the implementation. Copyright © The Computing Technology Industry Association, Inc. All rights reserved.
