What is domain name? Beginner’s Guide
Beginners often ask us: What is domain name, and how does the domain work? If you are one of them, you may have heard that you need a domain to create a website.
However, many beginners confuse domain names with websites or website hosting services. If you start, all these different terms might sound technical.
In this guide, I will answer what domain name and how the domain works. The aim is to help you understand and choose the right domain name for your website.
What is domain name?
A domain is the address of your website that is typed in the browser URL bar to visit your website. Put, if your website is home, your domain name will be the address.
More detailed explanation:
The internet is a computer giant network that is connected through global cable networks. Each computer is assigned an IP address to identify networks. The typical IP address looks like the following number:
Now an IP address like this is difficult to remember. Imagine if you have to use these numbers to visit your favourite website.
Domain names are created to overcome this issue. If you want to visit any website, you don’t need to enter a string length of numbers. Instead, you can visit it by typing a domain name that is easy to remember in the blade of your browser’s address.
How does the domain name works?
To understand how the domain name works, we will see what happens when you put it in your browser. When you enter the domain name in your web browser, it first sends a request to a global network that forms a domain name system (DNS).
These servers then search for a name server associated with the domain and forward requests to the name server. For example, if your website is hosted in Bluehost, the server information will be like this:
A computer manages this name server by your hosting company. Your hosting company will forward your request where your website is saved.
This computer is called a web server. It has special software installed (Apache, Nginx is two popular web server software). Web servers now take web pages and information related to it. Finally, then send this data back to the browser.
How do domain names different from websites and web hostings?
The website consists of files such as website builder software, HTML pages, images etc. If the domain is the address of your website, the web hosting is a home where your website lives. It is the actual computer where your website file is saved. Such computers are called servers and offered as services by the hosting company.
To create your website, you need a web domain name and hosting. However, it is essential to remember that they are two different services, and you can buy them from two different companies.

Domains are available in many different extensions. The most popular is .com. There are many other choices such as .org, .net, .tv, .info, .i, and more. But we always recommend using the .com domain extension.

Upper-level domain – TLD
Upper domain or TLD is a generic domain extension listed at the highest level in the domain naming system.
There are hundreds of them, but the most popular is .com, .org, and .net. Another TLD is less well known, and we do not recommend using it. For example, .biz, .club, .info, and more.
