ELI5: Explain Like I'm 5

.ac (second-level domain)

Alright kiddo, let me explain .ac (second-level domain) in a way you can understand!

First, do you know what a domain is? It's like an address for websites. Just like how your house has an address, websites have domains to help people find them on the internet.

Now, there are different types of domains. One of them is called a second-level domain. This is because it comes after the dot (.) in a website's address. So for example, in the address www.example.ac, the ".ac" is the second-level domain.

The .ac domain is actually a special one. It stands for the island of Ascension, which is a British territory in the South Atlantic Ocean. So when you see a website with a .ac domain, it might have something to do with that island!

Overall, .ac (second-level domain) is just a special type of website address that tells you something about the website you're visiting. Pretty cool, huh?
