Static
The "static" modifier means that a class cannot be instantiated, and the subroutines must instead be called directly.
if you had a class of human and created an instance of the human called wayne, the static modifier doesn't allow access such as wayne.example() , or wayne.example = 5, or Console.WriteLine(wayne.example). They are not avialable in an instance of a class.
Abstraction
The "abstract" modifier when declaring a class means that the class contains one or more abstract subroutine, and must have one or more subclasses for implementations of abstract methods. A subclass of an abstract class that is instantiated must implement any abstract subroutines contained in the abstract class.
Virtual
A virtual method is one which is inheritable and can be overridden.
