PaaS : Is Platform as a service : It means they provide what they provide - take it or leave it. GAE is an example of this. You can do whatever rules they set. You just concern yourself with application - not admin concerns like scaling, security ... .

Regular web hosting : essentially give you a *nix box for you to play with. You need to set it up, configure it and do the magic.

Regular web hosting can be virtual machines on the cloud like Rackspace, Amazon, Azure among others, or some guy renting you his machine in a basement, or something in between.
