"All devices or nodes in a network are organized in groups known as Domains or Workgroups. The key differences between these are their size. Workgroups are small networks, such as at home or in small offices. Large groups of computers in business or commercial environments are known as Domains. All the computers in a workgroup are considered peers and have access to each other with little or no control from one over the other. Network devices in a domain can access each other based on rules defined by network administrators. Users or nodes in a domain usually share resources like databases and output devices, whereas workgroup users maintain their own databases but may share output devices. Other differences involve security features, including access and authentication, and the ability to manage all of the computers from a central location, all of which are features of a domain."
