Namespace is a group of related elements in which each has a unique name or identifier. By the way, there are many types of namespaces, and each of them has a specific syntax that is used to define the corresponding elements. Each element is a ” local name ” within a namespace that serves as a unique identifier.
Namespaces are used in a lot of fields for computing, such as domain names, file paths, and XML documents. Here are some examples of different applications.
1. Domain Names – The namespace syntax of the Domain Name is specified by the Domain Name System, or DNS. This includes the top-level domain, (eg ” shouter.in “) and a subdomain, such as ” www .” While its URL www.shouter.in has the namespace identifier ” shouter.in “, while its local name is ” www .”
2. File Paths – File locations are specified using a file path, which includes multiple directories. A file path, which uses syntax that is defined with the operating system, is considered a namespace. For example, C: \ Program Files \ Internet Explorer is a namespace that indicates where the Internet Explorer files are on a Windows computer. This namespace / usr / local / apache / defines the location of Apache files on a Unix-based web server. Individual filenames also serve as unique identifiers under these directories.
3. XML Documents – XML namespaces (XMLNS) are used to associate the element and attribute names of a document with a namespace that is identified with an external URI. For example, an XML file may include HTML elements that are specified in http://www.w3.org/1999/xhtml . At the same time, its reference might look like “” at the top of the XML document.
The examples mentioned here are of some such namespaces that are used in computing. At the same time, they are also used to define network devices and other types of computer hardware . Additionally, computer programmers often use namespaces to group related variables under source code in a program.
By the way, all kinds of namespaces are mejhud, while they all serve the same purpose – which is to do a logical grouping of all related elements.
