An access specifier determines how other parts of a program
can access a class member.

Member access is controled by five access specifiers:

1. public,
2. private,
3. protected,
4. internal.
5. protected internal

1. public member can be accessed by any other code in
your program.
2. Main() is declared as public because it will be called
by code outside of its class (the operating system).
3. private member can be accessed only by other members
of its class.
4. A protected member is public within a class hierarchy,
but private outside that hierarchy.
5. A protected member is created by using the protected
access modifier.
6. The internal modifier declares that a member is known
throughout all files in an assembly, but unknown outside
that assembly.
7. The protected internal access level can be given only
to class members.
8. A member declared with protected internal access is
accessible within its own assembly or to derived types.
