What is the difference between a domain name and a website?
A domain name is the “address” of your website - the place your website is. Your website, on the other hand, is a collection of web pages that exist on the internet. You can’t access a website without entering its domain, but you can have a domain without a website.
Think of a domain like it’s a real-world house address, and think of your website as the house itself. While an empty plot of land still can still be identified by a specific street and number, your house can’t exist without being located in a specific place.
You can also use the same domain name for different websites (at different points in time). Just like you can knock down a house and build a brand new one in its place, so you can build a new website that’s “located” at the same address - your domain (you will have to remove the details of the old website, of course).
