Which of the following is an object-oriented technology
characteristic that permits an enhanced degree of security
over data?
A. Inheritance
B. Dynamic warehousing
C. Encapsulation
D. Polymorphism
Answer / guest
Answer: C
Encapsulation is a property of objects, which prevents
accessing either properties or methods, that have not been
previously defined as public. This means that any
implementation of the behavior of an object is not
accessible. An object defines a communication interface with
the exterior and only whatever belongs to that interface can
be accessed.
