So, what exactly an Abstraction is?
Abstraction facilitates the easy conceptualization of real world objects, by eliminating the unnecessary details of the object. Unnecessary details? Yes, all the similar objects when you generalize, you will drop the uncommon details about the objects.
E.g., when you model a generic prototype for CRT Television & a Plasma Television, you look for details like Type of screen, Height, Width, thickness etc.; these are necessary details for a Television. But a Television object doesn't need to have details of what kind of Electron it will bean to power the CRT, what kind of liquid plasmas it will use to power the Plasma TVs. These kinds of details are unnecessary details.
