Learn Web Development – Part 9 – What is Hosting & Domain?
Understanding domain names and web hosting — the essentials for launching a website.
In the previous part, we learned how a website is built step by step. But once a website is developed, it still needs to be published on the internet so that people can access it.
This is where domain names and web hosting come into play.
A domain name is the address of your website, while hosting is the place where your website files are stored.
What is a Domain Name?
A domain name is the unique address that users type in a browser to access a website.
Examples of domain names include:
- google.com
- wikipedia.org
- wpdevelopertips.in
Domain names make it easy for users to access websites without remembering complex IP addresses.
Example
Instead of typing a numeric IP address like 142.250.183.206, users can simply type google.com.
The domain name system automatically connects the domain to the correct server.
What is Web Hosting?
Web hosting is a service that stores your website’s files and makes them available on the internet.
Every website contains files such as:
- HTML files
- CSS stylesheets
- JavaScript files
- Images and media
- Backend scripts
- Databases
These files are stored on a server provided by a hosting company.
When someone visits your website, the hosting server sends those files to the user’s browser.
How Domain and Hosting Work Together
Domain names and hosting work together to make websites accessible.
The process usually works like this:
- A user enters a domain name in the browser.
- The domain is translated into an IP address using DNS.
- The browser sends a request to the hosting server.
- The server sends website files back to the browser.
- The browser displays the website.
