Method Signature:

The method signature consists of the method name and parameter list. When overriding a method, it must have the same signature as the original method in order to replace it.

Dynamic Binding: Dynamic binding refers to determining at runtime which implementation of an overridden method will be called based on the actual type of object being referred to.

Virtual Function: In languages like C++, virtual functions allow dynamic binding at runtime by using pointers or references to base-class objects.
