A workgroup is a logical collection of computers that share resources. Normally, workgroups are composed of the computers within a single department or a small company. Each computer can share resources with all other computers. In essence, all computers are of equal status. Within a company, different departments may be workgroups and each may have a unique name to identify the workgroup. Because each computer is independent, each computer is responsible for authenticating users. Like a workgroup, a domain is a logical collection of computers that share resources. One of the key differences is that a single server is responsible for managing security and other user-related information for the domain.
