URL – (Uniform Resource Locator)  What is it and what is it for? ▷ 2020

Often when we read an article on the web, they suggest that we can expand the information or know what is the source from which they got the data. This link, they usually show it with blue letters (pay attention that a hand appears automatically with the index finger pointing up).

Sometimes the only thing we can understand is the first part, in which there is a name of an Internet site that continues with a slash and the combination that we mentioned earlier.

This is nothing more than a “URL”, this acronym refers to the words in English ORniform Resource Locator, which translated into Spanish would be “Uniform Resource Locator”. In this article we will show you everything you need to know about the different URLs in computers and web pages so that you do not have doubts or fears when clicking on these links.

How are URLs classified and how is each different?

First of all, we should differentiate a URL from a URI (is the acronym for ORniform Resource Identifier, Unique Resource Identifier in Spanish). Without going into much detail, a URI contains a URL but never the other way around. The URL can change while a URI never changes. Sometimes a URL is a URI.

Many people confuse these terms and how We want to inform you correctly so that you do not have problems in the future when you are working with these topics.

Having clarified this point, we can say that a URL It is divided into two large groups:

Semantic url

Are those links in which they have a assigned format much easier to understand in a simple reading. This is used to see the location of a particular page within the website.

They are also called Friendly urls, since what is sought is that the user can easily remember the URL, thus discarding numbers, signs and other characters.URL in browser

Non-semantic URL

This resource locator does not have a simple logic in its reading and reflects the specific address in which it reflects where you can find, within a website, the related article in the location of that type of information. It is not highly recommended for SEO because Google rewards friendly URLs.

What are the parts or elements of a “Uniform Resource Locator”? Examples

Within the Uniform Resource Locator there is, like all things in computing, its well defined and detailed parts. Each one fulfills an important function within a scheme in which you cannot get anything out of this structure since each of these parts connects to the next.

Next, we will detail what each of these sections are in the structure and we will name it in the order in which they appear in a URL:

HTTP (Hypertext Transfer Protocol)

Between the server on which the website we want to see is hosted and the browser we have, there is a communication protocol in which the rules are defined so that our browser and that server can communicate with each other efficiently.

You may have noticed that in some URLs “https” appears, that is, an “s” is added at the end. This means that the protocol with which we are working is safe.


Two points

The colon is a way of separating the communication protocol from the rest of the web address.

Bars slanted to the right

It is necessary to clarify that both bars must be slanted to the right (//) since if they went the other way they would not work and a communication would not be found between the browser and the server. They serve to notify which is the address that we want to make the server contact our computer.


The most common among subdomains is the “www“(World WSDI Web), this is a set of protocols that serve for organization within the computer system. There are addresses in which this subdomain does not appear, which does not generate any problem when communicating with the server.


Now, it is time to tell the server what is the file we want to see or interact (this is what is generally called the domain of the Internet page). It can also be written as “default.html“or”index.htm“.

Its TLDs extension is the final part of the domain, and what it shows us is what kind of URL it is. To give some examples there are generic top-level extensions such as “.com“Or”.net“, You can find geographic extensions”.it is”(From Spain) or“ru“(From Russia), or related to education”.edu”.

Directory or folder

This part of a URL is to tell the server what part of the page we want to have on our screens.

Folders from a URL

Path, also called page

It is the file that we want to see inside the server. It is the same as with Windows or another folder-based system.


It is related to the symbol “#“and serves to give a specific order within the directory page that we have asked the server to see.
