A domain, in the context of a network, refers to any group of users, workstations, devices, printers, computers and database servers that share different types of data via network resources. There are also many types of subdomains. A domain has a domain controller, which governs all basic domain functions and manages network security. A domain, therefore, is used to manage all user functions, including username/password, and shared system resource authentication and access. A domain is also used to assign specific resource privileges, such as user accounts.
In a simple network domain, many computers and/or workgroups are directly connected. A domain is comprised of combined systems, servers and workgroups. Multiple server types may exist in one domain - such as Web, database and print - and depend on network requirements.
