A DNS name server is a server that stores the DNS records for a domain; a DNS name server responds with answers to queries against its database. The most common types of records stored in the DNS database are for start of authority ( SOA ), IP addresses ( A and AAAA ), SMTP mail exchangers (MX), name servers (NS), pointers for reverse DNS ...

[3] [4] A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.

An authoritative name server can either be a primary server or a secondary server. A primary server for a zone is the server that stores the definitive versions of all records in ...

A domain controller is a server running the Active Directory Domain Services (AD DS) role. It authenticates and authorizes all users and computers in a Windows domain-type network, assigning and enforcing security policies for all computers and installing or updating software.
A fully qualified domain name is conventionally written as a list of domain labels separated using the full stop "." character (dot or period). The top of the hierarchy in an FQDN begins with the rightmost label. For instance, in the FQDN somehost.example.com, com is a label directly under the root zone, example is nested under com, and finally ...
