Okay kiddo, so have you ever been to a library and wanted to find a book? The librarian might ask you for the book's location or address, like "What's that book's address on the shelf?" Well, a Uniform Resource Locator (URL for short) is kind of like a book's address on the internet.
When you want to go to a website, like YouTube or Google, you have to type in the website's URL into the search bar. The URL is made up of a few parts.
The first part is called the protocol, which is like the way you're communicating with the website. Most of the time, you'll see "http://" or "https://", which tells your computer how to talk to the website safely and securely.
The second part is the domain name, like "youtube.com" or "google.com". This tells your computer which website you want to go to.
Finally, there may be some extra information after the domain name, like "/watch?v=dQw4w9WgXcQ". This tells the website which specific page or video you want to see.
So remember, kiddo, a URL is like a website's address on the internet, made up of a protocol, a domain name, and sometimes extra information about a specific page or video.
