When you access something on the internet, you are accessing something on someone else's computer.

Computers have (effectively) postal addresses. When you want to access content on another computer, you type in its address.

But computer addresses don't look like "fedia.io" they look like "123.122.1.111".

When you type "fedia.io" your computer needs to go and ask what the computer's address is.

That's DNS. The Domain Name System. The system for finding the computer address from a domain name.

The above is very simplified and doesn't cover all scenarios, but I hope it's enough to get the idea.
