Chapter 1 Software Engineering Pressman

What is the "bathtub curve" in the context of hardware failure rates?

• It represents the ideal failure rate curve for hardware components.

• It illustrates the rise and fall of hardware failure rates over time.

• It demonstrates the impact of environmental maladies on hardware.

• It represents the cumulative effects of dust and vibration on hardware

According to the book, why does software not "wear out" like hardware?

• Software is not exposed to environmental maladies.

• Software undergoes continuous change, preventing wear.

• Software defects are easily corrected, ensuring longevity.

• Software maintenance tasks are less complex than hardware maintenance.

1. True or False: The failure rate curve for software follows an idealized curve similar to the hardware's bathtub curve.

• True

• False

What is one aspect that differentiates software maintenance tasks from hardware maintenance tasks?

• Hardware components can be easily replaced with spare parts.

• Software failures indicate errors in design or the development process.

• Software maintenance involves more complexity than hardware maintenance.

• Hardware maintenance requires frequent updates and changes

In the context of software engineering, what does "deterioration" refer to?

• The physical wearing out of software components over time.

• The decline in software quality due to continuous changes.

• The decrease in software performance due to environmental factors.

• The increase in software defects as time passes.

Software engineering is defined as:

• The application of engineering principles to software development.

• The process of creating software without any engineering principles.

• The management of software projects.

• The process of coding and programming software.

Which of the following is not a characteristic of good software?

• Efficiency

• Maintainability

• Flexibility

• Complexity

6. True or False: Software engineering is only concerned with the technical aspects of software development.

• True

• False

What are the primary activities of software engineering?

• Requirements analysis, design, coding, testing, and maintenance.

• Planning, marketing, and sales.

• Data collection, data analysis, and reporting.

• Troubleshooting and bug fixing.

Which software characteristic refers to the ability to undergo changes and modifications easily?

• Reliability

• Portability

• Maintainability

• Scalability
