What is the difference between static and dynamic binding?

What is the general problem with static scoping?

What is difference between static and dynamic polymorphism?

Static polymorphism is a type of polymorphism that collects the information to call a method during compile time while dynamic polymorphism is a type of polymorphism that collects information to call a method at run time. Thus, this is the main difference between static and dynamic polymorphism.
