What's the situation, feedback.html? page=2

Excuse me, what's the situation, feedback.html? page=2
Hello everyone
I see on the Internet there is a page, is a message page,
His page is feedback.html? page=2, and there are 10 messages on each page,
And his paging is [1],[2],[3] .... [9] So, each connection is feedback.html? Page=

It's so magical. That's how it's done. What I usually use is. php? Page=

Do not publish a message like the article to generate a static page, he is each page has 10 messages AH.
What's going on here, can you teach me a little bit?
