What are Domain Names and Hosting?
Domain Name and Hosting are important concepts that anyone starting to build a website or Landing Page will encounter.
These are highly technical concepts, so explaining them can be difficult to understand. Therefore, our motto is to “simplify” these concepts, helping you understand what a domain name and hosting are in just 5 minutes of reading this article.
What is a Domain Name?
Let’s take the easiest example: when you go out, why do you end up at a specific store? It’s because the store has a clear address such as house number, street name, district, etc., and you follow these directions to find the correct place.
Similarly, on the Internet, to reach the correct online store (website), you need its address.
The website address is called a Domain Name.
In reality, a website address is a string of numbers called an IP address (Internet Protocol), and this number is very hard to remember.
For example, the domain name “SimplePage.vn” is actually a long string of numbers like this: 45.119.83.79.
When you access this website, the browser is actually accessing the IP address 45.119.83.79, but you will only see the domain name “SimplePage.vn.”

What is DNS?
Because the IP address is difficult to remember, a system called Domain Name System (DNS) was created. The function of DNS is to “translate” these IP numbers into domain names (and vice versa) so you can remember them more easily.
When you enter the domain name “SimplePage.vn” in the search bar, DNS automatically translates this domain into the IP address 45.119.83.79 for the browser to access.
Thanks to DNS, you only need to remember the domain name to access any website instead of remembering the long IP number.
What is Hosting?
The land or property a store owns or rents is equivalent to the hosting of a website.
Simply put, Hosting is the STORAGE SPACE for a website’s data. This includes:
-
Website source code
-
Database (orders, images, videos, articles, etc.)
To own hosting, you need to rent it from hosting providers on the Internet (search online to learn more).
When you register for hosting, the hosting provider will give you space to store the website’s data in an online environment.
Each hosting space is assigned a unique IP address, to which you can point your domain name. (If your domain is not pointed to the correct IP address of your hosting, the website will not be accessible.)
These hosting providers ensure that the hosting service operates 24/7, meaning your website will always be online.
