What Is Web Hosting

It is possible that you are overwhelmed by the amount of information that you can find on the internet, and you do not know well what services you are going to need to start your digital project.

To clarify these concepts, we will learn in this article what is the basic service you need to create a WordPress website, Joomla! Or Drupal and how it works: we are talking about web hosting. Certa is a best company in the web hosting world you can learn more about Certa.

What is web hosting?

We understand that you are starting, that you have little knowledge, so we will try to understand what it is without going into technical details.

First of all, it is essential that you know that every web application is made up of a series of files and directories that contain the information of the same. From the simplest that will be an .html file to some CMS (content manager) such as WordPress.

These data, as with any application you have on your computer, must be stored somewhere.

The hosting is nothing more than a medium that lets you have stored your web site and is available 24 hours worldwide.

At this point, you will be asking yourself, “So … what is the difference between having my website on my computer and hosting it on a hosting service?”

Hosting companies have specific machines (called servers) for web hosting, so they guarantee you and provide essential features that you could not obtain with a computer. Let’s see what they are:


Unlike your computer, to be able to service a website, it is necessary that the servers are always on and connected to the internet. Keep in mind that, in the end, what you want is for your website consistently to be available worldwide.

Therefore, you will need a professional connection and bandwidth that other types of domestic relations cannot provide. Any error stopped on the computer or the internet connection, would cause your website to crash.


Hosting providers such as Webempresa ( hosting Spain ) have specific servers focused on web service and allowed optimizing the performance and operation of applications.

Hosting: performance

Easy to use

Most hosting already have all the necessary services ready (Apache web server, MySQL databases, etc.) to service the page. In this way, once you host it on the servers, your application starts working.

In addition to this, they have a control panel (for example, cPanel) from which you can manage everything related to hosting directly: file manager, email account management, backups, etc.


You already know that a web page is a very juicy element for “cyber-bad guys” since they can use it to send SPAM, obtain vulnerable information and data, etc.

Hosting service providers have a series of security measures such as antivirus or firewalls, among others, that help you keep your website secure so that it is much more challenging to violate than if you have it on your computer. Avoid risks!

As we have seen, a hosting is made up of servers (machines) that store the files that make up the website and have all the necessary services so that it can be viewed and interacted with from any computer.

But how do we access it?

An IP address identifies the hosting servers. Since this is difficult to remember, domains come into play. These domains are connected to other DNS servers (domain name servers) which are the ones that will translate to which IP they must “look” to load the web.

Basically and roughly, when someone types an address (domain) in their computer’s browser, it connects to their configured DNS and translates the address to the server’s IP.

The server receives the access request and sends the data packets with the information from the hosted web page so that it can be viewed on the computer from which the request was made.

At this point, the domain tends to be confused with the web application and hosting itself, but all three are independent.

Although it will not be discussed in this article, it must be clear that the domain is only the name of each site, which can be configured to “look” towards a hosting (thanks to its DNS servers) and thus load the website that you have stayed in the accommodation they are targeting.


With all these data, we can conclude that hosting is one of the fundamental pillars to be able to mount your web project.

Web hosting is the place where you will have all the files of your application hosted so that it is accessible from all over the world and at all times. We could equate hosting with a hotel for your web pages.

The hotel (web hosting) offers you service so that you can stay comfortably in it and where to protect your belongings (webs).

This guarantees your security so that you are not robbed, electricity, hot water, internet and other services that allow you to be in it. Also, it offers support for any problem you may have so that your stay is as pleasant as possible.
