If they were present in SharePoint 2010 then what is the difference between SharePoint 2010 apps and SharePoint 2013 apps?

Answer 1

Apps was introduced in SharePoint Server 2013 and is based on a new concept usually depending on client side code, especially in Office 365. But on premise you can still use .net framework to produce apps for SharePoint Server.

An app is supposed to work in an isolated container who shouldn't have the potential or risk to break a SharePoint Page, which a web part can. The aim from Microsoft is to secure SharePoint from potentially malicious code, making SharePoint unresponsive.

The intention is also for the App to consume REST APIs for everything it does, but it doesn't have to be that way. Read more on...
