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.
Namespaces are a required aspect of functioning containers in Linux. The term "namespace" is often used to denote a specific type of namespace (e.g., process ID) as well as for a particular space of names. [1] A Linux system begins with a single namespace of each type, used by all processes.
Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent ...
In Windows Shell programming, the Windows Shell namespace is an organized tree-structured hierarchical representation that Windows Explorer facilitates to graphically present file system contents and other objects to the end user. Conceptually, the Shell namespace may be regarded as a larger and more inclusive version of the file system.
MIBs describe the structure of the management data of a device subsystem; they use a hierarchical namespace containing object identifiers (OID). Each OID identifies a variable that can be read or set via SNMP. MIBs use the notation defined by Structure of Management Information Version 2.0 (SMIv2, RFC 2578), a subset of ASN.1.
Namespaces can be delegated to other namespace authorities. Federation Namespaces defined separately at any level can be joined together (in a hierarchical or polyarchical fashion) and made visible and resolvable. Persistence The ability to express the intent that parts (or all) of an XRI are permanent identifiers that will never be reassigned.
The DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet.. Before October 1, 2016, the root zone had been overseen by the Internet Corporation for Assigned Names and Numbers (ICANN) which delegates the management to a subsidiary acting as the Internet Assigned Numbers Authority (IANA).

In general, the reason for this lack of allowance for duplicate names through hierarchical directory placement is that Microsoft primarily relies on the principles of NetBIOS, which is a flat-namespace method of network object management that, for Microsoft software, goes all the way back to Windows NT 3.1 and MS-DOS LAN Manager. Allowing for ...
