Stand-alone DFS Namespace In a stand-alone DFS namespace, the path to access the root or a link starts with the root server name. The stand-alone DFS root can comprise of a single root target. Therefore, these are not fault tolerant. When the root target is not available, you cannot access the complete DFS namespace. You can enable fault tolerance on a stand-alone DFS namespace by creating these namespaces on a cluster of servers. A stand-alone DFS namespace has its configuration information stored in the local registry of eth root server. Domain-based DFS Namespace In a domain-based DFS namespace, the path to access the root or a link starts with the domain name of the host. The domain-based DFS root can comprise of single or multiple root targets that enables fault tolerance and load sharing. A domain-based DFS namespace has its configuration information stored in the Active Directory. Exemple : • \\DomainName\RootName: This is the format of the namespace when you select the Domain-based DFS namespace type. • \\ServerName\RootName: This is the format of the namespace when you select the Stand-alone DFS namespace type.
A domain is a portion of the overall DNS namespace. A zone, however, can contain multiple contiguous domains.
the root domainDNS namespace: DNS is the name service provided by the Internet for TCP/IP networks. DNS is broken up into domains, a logical organization of computers that exist in a larger network. The domains exist at different levels and connect in a hierarchy that resembles the root structure of a tree. Each domain extends from the node above it, beginning at the top with the root-level domain. Under the root-level domain are the top-level domains, under those are the second-level domains, and on down into subdomains. DNS namespace identifies the structure of the domains that combine to form a complete domain name. For example, in the domain name sub.secondary.com, "com" is the top-level domain, "secondary" identifies the secondary domain name (commonly a site hosted by an organization and/or business), and "sub" identifies a subdomain within the larger network. This entire DNS domain structure is called the DNS namespace. The name assigned to a domain or computer relates to its position in the namespace.

in-addr.arpa domain Before reverse lookups were introduced, DNS needed to search all the domains in the DNS namespace to identify the hostname corresponding to an IP address. This took a large amount of processing time. To overcome this problem, the in-addr.arpa domain was created, which contains the required DNS records for reverse lookups. The in-addr.arpa domain is a reserved Internet DNS namespace.

Here's one: there's no namespace in C

Of course! All namespaces are nested by default since all namespaces exist in the global namespace. A class is also a namespace; therefore classes can also be nested.
A public function is scoped to the class in which it is declared. If declared non-static, then it must be invoked against an instance of the class but if declared static then namespace resolution is required to access the function. A non-member function is not scoped to any class but may be scoped to a namespace. If no namespace is specified, then it is scoped to the (unnamed) global namespace. If scoped to any other namespace then namespace resolution is required to access the function.
A global object is any object instantiated in the global namespace. The global namespace is anonymous, so if we don't explicitly specify a namespace prior to instantiating an object, that object will be instantiated in the global namespace: int x; // global namespace n { int x; // non-global }; To refer to the non-global, we must use namespace resolution: x = 42; // assign to the global n::x = 42; // assign to the non-global
