How your website is supported: Domain- Host – Server – Data centre.

Target skills

Learn about the main components that make a website available in the web.

How to give birth to your website, or in other words – how to bring your web site to the Internet?
No matter what type of website you create, there are 4 main parts that collaborate in order to make your site go live.

Domain Name

First of all, your site would need an address so that anybody would know where to find it.
The domain name is the address of your website that people type in the browser’s URL bar to visit your website.

The internet is basically a huge network of connected computers. In order to be identified within this network each computer has an IP address, which is a series of numbers separated by dots: 78.256.66.2. The computers have no problem remembering these numbers and searching for each other by the IP address, but for us it can pose a problem. To solve this problem, the domain name was invented. It can use words instead of numbers so it is easy to remember a website address.

Web Hosting

Now that your site has got an address, you need to provide housing for all its content. This is provided by web hosting.
Web hosting is a place where all the files of your site live.
You usually pay a company that gives you this place on their computer. When someone introduces your domain name in a browser, this name is translated into an IP address of the company´s computer. This computer that stores all your website´s files sends them back to the user´s browser.

Domain name and web hosting are 2 different services, but both are needed to make websites function. Usually web hosting companies provide both services and it is more convenient to manage them. Although, you can get them separately from different providers.

The computer that stores your website´s information as well as a lot of other data (e-mails, database, website builder, control panels) is called a server.

Therefore, if we compare our website to a house, then a web hosting server would be a plot of land where it is built and a domain name would be our home address.

Data Centres

Servers usually form part of a data centre.
A data centre is a building that provides space, power and cooling for a big network infrastructure. The networks are composed of servers.
Data servers store, share, process and manage large amounts of data.
