What Does Url Stand For?

URL stands for Uniform Resource Locator and is a reference or address to a resource on the Internet.

Uniform Resource Locators are also called as Uniform Resource Identifiers. They are short strings that identify resources on the web that are documents, images, downloadable files, services, electronic mailboxes, and other resources. They make resources available under a variety of naming schemes and access methods such as HTTP, FTP, and Internet mail addressable in the same simple way.

The acronym "http" stands for Hypertext Transfer Protocol.

The following is an example of a URL:

www.blurtit.com

A URL has two main components:

Http: -- is the Protocol Identifier
//www.blurtit.com:-- is the resource name.

The protocol identifier and the resource name are always separated by a colon and two forward slashes. The protocol identifier indicates the name of the protocol to be used to fetch the resource. The example uses the Hypertext Transfer Protocol (HTTP), which is typically used to serve up hypertext documents.

The resource name has one or more of the following components:

Host Name: The name of the server on which the resource is present.
Filename: The path name to the file on the machine
Port Number: This is optional … it indicates the port number to which to connect
Reference: This is optional as well .this is a reference to a named anchor within a resource that usually identifies a specific location within a file.

The full form of URL is 'Uniform Resource Locator'. It is a technical web-based term which is used in two separate meanings. In day-to-day basis, URL is a renowned synonym for Uniform Resource Identifier (URI).

In stringent technical usage, it is a subset of URI precise to identifiers who are chief locators. The basic idea was of a standardized syntax for universal identifiers and user of network-retrievable document of the World Wide Web. But later these names were deceptive because all the identifiers were locators. Thus by the time RFC 1630 officially define URI as a standard term best suitable for this concept, the word "URL" had become popular world wide.

In strict technical theories URL is defined as a URI which is "in addition to recognize a resource, provides a way of locating the source by describing its chief access mechanism."
