Domain
A Domain is a group of computers that are connected by both hardware and
software so that files can easily be shared between users. The key difference
between a workgroup and a domain is that in the latter, the Primary Domain
Controller (PDC) maintains database regarding which users and groups have access
to the files and shares that exist on the computers that belong to the domain. This is
contrast to a Microsoft Windows Workgroup, where each computer that belongs to
the workgroup maintains a database of which users can access its files and shares.
The diagram below is a representation of a typical domain; notice how the PDC
maintains a list of the users who have access to the files and shares for each
computer.
Dynamic Host Configuration Protocol (DHCP) Server
A DHCP server automatically assigns IP (Internet Protocol) addresses to client
machines on a TCP/IP network. Typically, the System Administrator provides the
DHCP manager software a range of available IP addresses, and then the DHCP
Server assigns available IP addresses to client PCs as needed.
