• private: Private declared variables, classes or functions can be accessed only by the member functions. No one from outside the class can access them.
• protected: This access specifier is useful in a hierarchy wherein an access can be given only to the child classes.
• internal: These limit an access only within an assembly. Its is similar to a friend function of C++.
• protected internal: These limit the access within the assembly and to the child classes in the hierarchy.
