the default accessibility for interface is PUBLIC

Gnome.
Yes, Interface mehtods are public by default so that they could be implemented by every class implementing the interfaces.
All variables in an interface are by default public static and final and hence they are Constants.
The FastEthernet interface of R1 is disabled. One of the default routes is configured incorrectly. A routing protocol is not configured on both routers. The default gateway has not been configured on both routers.
The public, protected and private keywords only apply to object oriented programming languages. They are used to determine the accessibility of specific class members and their bases. Private members are only accessible to the class and to friends of the class. Protected members are the same as private but are also accessible to derivatives of the class. Public members are accessible to all code. When applied to base classes, the public, protected and private keywords can be used to either maintain or reduce the accessibility of the base class members (but never to increase their accessibility). When declared public, the accessibility of the base class members remains as defined by the base class. When declared protected, the public members become protected members. And when declared private, all members of the base class become private members. As well as defining the overall accessibility of the base class members, the accessibility of individual base class members can also be specified.
Public members in C++ have accessibility to any function that has scope to the instance of the class, whereas private members have accessibility only to functions of that class.

It depends on the context (stand alone, within or outside of a class). Because it is context sensitive, I prefer to declare it the accessibility explicitly to avoid the confusion.
The default user interface for Windows Vista and Windows 7 is called Windows Aero.
Public data members are akin to structure data members (which are public by default). Since they are public, they are fully exposed outside of the class. Data validation becomes impossible. Even if you define an interface, there's no requirement to use it since the members are readily available. If the members must be validated, do not assign them public access.
