Job Profiles in SharePoint.

Hey,

May be it is a stupid question from my side but lots of confusion in these common profiles terms related to SharePoint.

SharePoint Developer

SharePoint Architect 

SharePoint Consultant

SharePoint Programmer

SharePoint Designer

SharePoint Administrator

SharePoint Power User

SharePoint End User

and many other profiles(don’t know the exact name).

Can anyone explain each with a real life example?

Thanks in advance!
