Answer» CORRECT ANSWER is (b) APPLICATION layer For explanation: The application layer This layer delivers the application-specific functionality that is required.

9.	Reverse engineering is the last activity in a reengineering project.(a) True(b) FalseI got this question by my college professor while I was bunking the class.This intriguing question comes from Software Evolution in portion Software Evolution of Software Engineering
Answer» Correct choice is (b) False Easiest explanation: Reverse engineering is often the INITIAL ACTIVITY in a REENGINEERING project.

10.	A sociotechnical system is a system that includes(a) people(b) software(c) hardware(d) all of the mentionedI have been asked this question in class test.This is a very interesting question from Sociotechnical Systems in section Software Evolution of Software Engineering
Answer» Right choice is (d) all of the mentioned For EXPLANATION I would say: A sociotechnical system is a system that includes people, SOFTWARE, and HARDWARE to show that you NEED to TAKE a systems perspective on security and dependability.

11.
