What is the difference between a hosted and a non-hosted AdSense account?

Hosted account - The important point of this account is that its approval is very easy .You can easily approve a hosted AdSense account from Google hosted sites like Blogspot, hubpages, You tube, etc.

Non-hosted -  This account can be used any site. It's very difficult to approve a non-hosted or publisher account but once if your account got approved it cannot be easily blocked. You can also use it on Windows apps and mobiles to earn money.
