In computer programming, namespaces are typically employed for the purpose of grouping symbols and identifiers around a particular functionality and to avoid name collisions between multiple identifiers that share the same name. In networking, the Domain Name System organizes websites (and other resources) into hierarchical namespaces.
In computing, a naming scheme is a system for assigning and managing names of objects connected into computer networks. It typically consists of a namespace and processes for assigning, storing, and resolving names.
In computing, a directory service or name service maps the names of network resources to their respective network addresses.It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects.
For example, if a process has administrative permission to change the IP address of a network interface, it may do so as long as its own user namespace is the same as (or ancestor of) the user namespace that owns the network namespace. Hence, the initial user namespace has administrative control over all namespace types in the system. [11]
Namespace security in the Domain Name System [ edit ] In the digital age , the significance of namespace security has been magnified as the internet is predominantly navigated through the use of the Domain Name System, which constitutes a collection of namespaces, which together comprise the Internet as defined by the Internet Assigned Numbers ...
The Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks.
A name server is a computer application that implements a network service for providing responses to queries against a directory service.It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component.
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme.URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable.
