By visibility I assume you mean member accessibility. C++ uses three levels of accessibility: private, protected and public. Private members are only accessible to the class itself and friends of the class. Protected members are the same as private members except derived classes also have access. Public members are fully accessible.
With regards inheritance, base class members with greater access than that specified are reduced to the specified access in the derived class. Thus public inheritance has no effect on base class member access. Protected inheritance reduces public members of the base class to protected members of the derived class. Private inheritance reduces both public and protected members of the base class to private members of the derived class. Private members of the base class are never inherited, thus they always remain private to the base class. Note that access to base class members can never be increased through inheritance, only reduced or kept the same. However, as well as defining an overall inheritance access, you can also specify member-wise inheritance access. Thus you could use public inheritance overall, but specify certain public members of the base class to be protected or private in the derived class and/or certain protected members of the base class to be private members of the derived class.

Operating systems of computers have various modes designed to conserve power. Two power saving modes are sleep and hibernation, which can allow for fast resumption of access.

Transverse modes are classified into different types:TE modes (Transverse Electric) no electric field in the direction of propagation.TM modes (Transverse Magnetic) no magnetic field in the direction of propagation.TEM modes (Transverse Electromagnetic) no electric nor magnetic field in the direction of propagation.Hybrid modes nonzero electric and magnetic fields in the direction of propagation.
