What is URL Full Form?: Uniform Resource Locators (URLs)

URL full form is “Uniform resource locators

URL is one of the most important Web concepts, along with Hypertext and HTTP. Browsers employ this technology to obtain any online resource that has been published.

URL is the full form of Uniform Resource Locator. A URL is the address of a certain unique resource on the Internet. Each valid URL, in principle, refers to a single resource. An HTML page, a CSS document, a picture, and so on are examples of such resources. There are few exceptions in practice, the most frequent of which is a URL linking to a resource that no longer exists or has migrated. Because the Web server is in charge of both the resource represented by the URL and the URL itself, it is up to the web server’s owner to properly manage that resource and its associated URL.

A URL is made up of several elements, some of which are required and others which are optional. On the URL below, the most significant components are underlined (details are supplied in the following sections:

The scheme is the first element of the URL, and it specifies the protocol that the browser must use to request the resource (a protocol is a set method for exchanging or transferring data around a computer network). HTTPS or HTTP is the most common protocol for web pages (its unsecured version). Although one of these two is required to address a web page, browsers can also handle additional schemes such as mailto: (to launch a mail client), so don’t be shocked if you encounter others.

The authority is then followed by the pattern:/, which separates it from the scheme. If both the domain (e.g. www.example.com) and the port (80) are present, the authority includes both:

• The domain identifies the Web server that is being accessed. This is usually a domain name, although it might also be an IP address (but this is rare as it is much less convenient).

• The port is the technical “gate” that allows you to access the web server’s resources. If the web server grants access to its resources using conventional HTTP ports (80 for HTTP and 443 for HTTPS), it is frequently removed. Otherwise, it is required.

How to Make Use of URLs

To access the resource behind any URL, put it directly into the browser’s address bar. This, however, is just the top of the iceberg!

URLs are used extensively in the HTML language, which will be described later:

• to display media such as pictures (with the img> element), videos (with the video> element), sounds and music (with the audio> element), and other HTML documents (with the iframe> element); • to link a document to its relevant resources using various elements such as link> or script>;

Absolute URLs vs relative URLs

An absolute URL is what we saw above, but there is also something called a relative URL. Let’s take a closer look at what that distinction entails.

The needed portions of a URL are heavily influenced by the context in which it is used. Because a URL in your browser’s address bar has no context, you must offer a full (or absolute) URL, such as the ones we saw earlier. You don’t need to provide the protocol (the browser defaults to HTTP) or the port (which is only required if the targeted Web server uses an uncommon port), but you must include all of the other components of the URL.

Things are a little different when a URL is used within a document, such as in an HTML page. The browser may utilise this information to fill in the missing elements of any URL available inside that page because it already has the document’s own URL. By examining simply the path portion of the URL, we can distinguish between an absolute and a relative URL. If the path component of the URL begins with the “/” character, the browser will fetch the resource from the server’s top root, bypassing the current document’s context.

Semantic URLs

Despite their technical nature, URLs serve as a human-readable gateway to a website. They can be remembered and typed into a browser’s address bar by anyone. Because people are at the heart of the Internet, creating what are known as semantic URLs is considered best practise. Semantic URLs make use of words with intrinsic meaning that everyone may understand, independent of technical knowledge.

Computers, of course, are unconcerned with linguistic semantics. You’ve most likely come across URLs that appear like a jumble of strange characters. However, there are several benefits to establishing human-readable URLs:

  • You can manipulate them more easily.
  • It explains things for users in terms of where they are, what they’re doing, what they’re reading, and what they’re engaging with on the Web.
  • Some search engines can utilize semantics to enhance the categorization of connected pages.
