Software Engineering Chapter 1 Quiz

Frequently Asked Questions about Software Engineering

• Key challenges include increasing diversity, demand for reduced delivery times, and the need for trustworthy software.
• Software costs are approximately 60% for development and 40% for testing; in custom software, evolution costs can surpass development costs.
• Effective software engineering techniques vary based on the system type, such as prototyping for games and comprehensive specifications for safety-critical systems.
• The web has revolutionized software engineering by increasing the availability of software services and enabling the development of highly distributed systems.

Software Products

• Generic products are stand-alone systems marketed to any customer.
• Interactive transaction-based applications run remotely and are accessed through user PCs, exemplified by e-commerce platforms.
• Embedded control systems govern hardware devices, with a greater quantity of these systems in existence compared to other types.

Application Types

• Batch processing systems handle large volumes of data inputs to generate outputs efficiently.
• Entertainment systems are designed for personal use and focus on user entertainment.
• Modeling and simulation systems help scientists and engineers replicate physical processes involving multiple interacting objects.
• Data collection systems gather environmental data using sensors for further processing.
• Systems of systems comprise multiple software systems integrated into a larger framework.

Software Engineering Fundamentals

• Fundamental principles, like using a managed development process, apply across all software types, albeit with varied processes suited to different software.
• Dependability and performance are crucial for all systems.

Web Software Engineering

• Service-oriented systems utilize stand-alone web services for software implementation.
• Rich interfaces are enhanced by technologies like AJAX and HTML5, enabling advanced web browser capabilities.

Software Engineering Ethics

• Involves responsibilities beyond technical skills; ethical behavior is essential for professional respect.
• Ethical standards involve adherence to moral principles alongside legal requirements.

Issues of Professional Responsibility

• Confidentiality should always be respected regarding employers and clients, with or without formal agreements.
• Engineers must accurately represent their competence and avoid taking on work beyond their capabilities.
• Awareness of intellectual property laws is critical to protect employers’ and clients' copyrights and patents.
• Engineers must refrain from misusing others' computers, which can range from minor infractions to serious offenses.

ACM/IEEE Code of Ethics

• Developed by professional societies in the US, detailing ethical practice for software engineers.
• Members commit to eight principles guiding their professional behavior, applicable to practitioners, educators, and policy makers.

Rationale for the Code of Ethics

• Software plays a pivotal role across various sectors (commerce, government, etc.), instilling a responsibility for software engineers in design, development, and testing.
• Engineers have the opportunity to impact society positively or negatively, necessitating a commitment to ethical practices in software engineering.

Wilderness Weather Station

• To enhance weather monitoring in remote areas, several hundred weather stations will be implemented.
• Stations collect and measure data like temperature, pressure, and wind characteristics through embedded software systems.
• Each instrument periodically records data and manages information collection.

Weather Information System

• The weather station system processes and transmits collected weather data.
• The data management system archives data collected from all stations, facilitating analysis and storage.
• The maintenance system monitors the health of the weather stations through satellite communication, reporting any issues.

Additional Software Functionality

• Systems will also include the capability to monitor instruments and report any faults related to power and communication hardware.
