Test Questions for Chapter 14

Test Questions for Chapter 14

1. T F Software are the devices on a computer system that are used to store or archive data for later use.

2. T F Assembly languages mimic the structure and organization of machine languages on which they are based. However, assembly language programs are both symbolic and portable to other machines.

3. T F Symbolic programs--whether written in assembly or high-level programming languages--require translation programs that prepare them for execution on a particular processor.

4. T F The scale and complexity of modern commercial software development necessitates a division of labor among teams of individuals assigned to the project.

5. T F In commercial software development, most program testing is performed by the programmers who write and develop the product.

6. T F Most software systems can be certified for validity, that is, error-free performance in all instances.

7. T F Most programs today are designed and written using high-level programming languages rather than binary-encoded machine languages.

8. T F While there are many different instances of high-level programming languages, all of these fit a single consistent paradigm.

9. T F Codes of ethics for software professionals are especially effective due to their enforcement by governing bodies of professional organizations and societies.

10. T F The risks from the problems encountered in the performance of software systems are due to the inherent complexities associated with the design and development of such systems.

9. Designing and developing software systems involve

a. complexities inherited from the task or problem attempted.

b. complexities involved in creating programs to solve such problems.

c. complexities due to the unpredictability of software systems in performance.

d. all of the above.
