10 Questions
What are the characteristics of software?
- Software is developed or engineered; it is not manufactured. 2. Software doesn't 'wear out'. 3. Although the industry is moving towards component-based constructions, most software continues to be custom built.
What is software?
Software is a set of instructions that when executed, provide desired features, functions, and performance. It is a data structure that enables programs to manipulate information. Software is also a document that describes the operation and use of programs.
What is the Bathtub Curve used for?
The Bathtub Curve is used to illustrate hardware failure and software failure over time.
What are the types/categories of software mentioned?
- System Software 2. Application Software 3. Engineering/Scientific Software 4. Embedded Software 5. Product-line Software 6. Web applications 7. Artificial Intelligence Software
What is system software?
System software is a collection of programs written to service other programs.
Explain the concept of 'Bathtub Curve' in relation to software failure.
The Bathtub Curve illustrates the failure rate of software over time. It consists of three phases: an initial high failure rate due to design and implementation flaws, a period of low failure rates as these issues are resolved, and a final increase in failure rates as software ages and becomes outdated.
Distinguish between system software and application software based on their purpose and functionality.
System software is designed to provide a platform for running application software and managing the hardware, while application software is developed to perform specific tasks for the end user, such as word processing or data analysis.
Explain the significance of the statement 'Software is developed or engineered; it is not manufactured.'
This statement highlights the fact that software development involves a creative and problem-solving process, rather than mass production. It emphasizes the design, construction, and maintenance aspects of software development as opposed to traditional manufacturing processes.
Discuss the implications of the statement 'Software doesn't wear out' in the context of software maintenance and evolution.
This statement implies that software does not degrade over time like physical products do. However, it does require ongoing maintenance and updates to adapt to changing environments, technologies, and user needs, making software evolution a critical aspect of its lifecycle.
Explain the transition from custom-built software to component-based constructions and its impact on the software industry.
The transition signifies a shift towards reusability and modular design, aiming to improve efficiency and reduce development time. It has the potential to transform the industry by promoting standardization, interoperability, and rapid application development, while also posing challenges in terms of integration and quality assurance.
