How do etherpad & Google Docs do ChangeSets

Question

I'm curious to learn how Etherpad and Google Docs automatically save data. When you're writing a text document the products send only the changes to the server. Any idea how this technology works and where I can go to learn more about the end-2-end?

Thanks
