URL is an acronym for Uniform Resource Locator. It is the string of characters that follows a pattern and that allows naming resources within the Internet environment so that they can be located.
Text documents, photographs and audio, among other types of digital content, have a URL when they are published on the Internet. These locators allow you to create hyperlinks (also known as hyperlinks or links) on the World Wide Web (WWW), making navigation easier. The URL is therefore the character set that allows a unique address to be assigned to a resource available in virtual space. In other words, the URL is an Internet address that, when found and viewed by a browser, displays an information resource to the user.
So, for example, we can use our own web page (Definition of) as an example. Specifically, it should be noted that the URL referred to in this space is none other than https://definicion.de. For example: “The URL of the most used search engine on the Internet is http://www.google.com”, “I have been trying to access your page, but it seems to me that the URL is registered incorrectly”. The sequence of characters in the URL combines different information, such as the name of the computer that provides the contents, the directory in which they are hosted, the name of the referred file, and also the protocol that will be used to retrieve the data. The URL scheme indicates the network protocol used to retrieve information from the identified resource. URL schemes include http, https, mailto, and ftp. In this sense, we can establish, for example, that http (HyperText Transport Protocol) is the protocol most used at the moment to transmit hypertext, while https (HyperText Transport Protocol Secure) is the one used to connect to Internet servers that they are safe. This security means that personal data or credit card numbers cannot be intercepted as they are encrypted. Mailto, another of the protocols mentioned above, is used to send email and ftp (File Transfer Protocol) is used to transfer files of various types. These are some of the best known and most used protocols, but there are many more, such as news, which allows access to news services, or telnet, which gives the possibility of connecting to what is a multi-user machine. The latter, we can establish that it is used, among other places, in libraries. It should be noted that the URL is currently considered part of the Uniform Resource Identifier (URI) along with the Uniform Resource Name (URN).
It is worth noting the first of those mentioned, which is a much more complete identifier than any URL, which is made up of the following elements: scheme, authority, route, query and fragment. While the URN should be made clear that it works very similarly to the aforementioned URL, it does have one difference though: it doesn’t clearly express where the object is.
