What is a URL, what is it for and what do your initials mean in computing and web pages?

What is a URL

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

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

This is nothing but a “URL” , this acronym refers to the English words U niform R esource L ocator, 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 computing and on web pages so you have no doubts or fears when clicking on these links.

How are URLs classified and how is each different? / span>

First of all, we should differentiate a URL from a URI (stands for U niform R esource I dentifier, Unique Resource Identifier in Spanish). Without going into many details, a URI contains a URL but never the other way around. The URL may change while a URI never changes. Sometimes a URL is a URI.

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

Clarified this point, we can say that a URL 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 special 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.

Non-semantic URL

This resource locator does not have a simple logic in its reading and reflects the specific direction in which it reflects where you can find, within a website, the related article in the location of that type of information. It’s 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 one of those parts connects to the next one.

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

HTTP (Hypertext Transfer Protocol)

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

You will have noticed that in some URLs “https” appears, that is to say 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 to separate the communication protocol with the rest of the web address.

Bars tilted to the right

It is necessary to clarify that the two bars should be tilted to the right (//) since if they were otherwise they would not work and a communication between the browser and the server would not be found. They serve to notify us of the address we want to make the server contact our computer.

Subdomain

The most common among subdomains is the “ www ” ( W orld W ide W eb) , this is a set of protocols that are used for the 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.

Index.html

Now, it’s time to tell the server what file we want to see or interact with (here is what is usually called the domain of the website). 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 geographical extensions “ .es ”(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.

Carpetas de un URL

Route, also called page

It is the file we want to see inside the server. The same applies to Windows or another folder-based system.

Tag

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