Answer / guest
Answer: D
Old (legacy) systems that have been corrected, adapted and
enhanced extensively require reengineering to continue to be
maintainable. Reengineering is a rebuilding activity to
incorporate new technologies into existing systems. Using
program language statements, reverse engineering involves
reversing a program's machine code into the source code in
which it was written to identify malicious content in a
program such as a virus, or to adapt a program written for
use with one processor for use with a differently designed
processor. Prototyping is development of a system through
controlled trial and error. Software reuse is the process of
planning, analyzing and using previously developed software
components. The reusable components are integrated into the
current software product systematically.

Answer / kasturi
Answer D. Reverse engineering is done on the exisitng system
to understand its logic and design. Reengineering is to
rebuild it after the incorporating this understanding into
the new system.Since the question states existing system is
being enhanced by reusing design, this is an example of
reengineering, using reverse engineering.
