1. Introduction of Software and Software Engineering

Agile methodologies emphasize:

• Iterative development and continuous feedback
• Detailed planning and upfront requirement gathering
• A single developer working on the entire project
• Focus on code quality over user needs

Common SDLC phases include:

• Planning
• Requirements gathering
• Design
• All of the above

Complexity in software refers to:

• The number of lines of code
• The difficulty of understanding and modifying the code
• The speed at which the software executes
• The user interface design

During the development phase in the Waterfall model:

• The code is written based on the approved design
• Unit testing is performed to ensure individual modules function correctly
• Integration testing verifies how different modules work together
• All of the above

Effective communication and collaboration are crucial for:

• Successfully implementing a layered approach
• Choosing the most visually appealing user interface
• Writing efficient code in a single language
• Meeting unrealistic deadlines

Modifiability refers to the ease of:

• Learning the software for the first time
• Fixing errors and adding new features
• Making the software run faster
• Understanding the code structure

Myth: Fixing a bug in software weakens the program overall.

• True
• False
• Depends on the type of bug fix
• Uncertain

Myth: The more features a software program has, the better it is.

• True
• False
• Depends on user needs and complexity
• Uncertain

Myth: Writing code is the most important aspect of software development.

• True
• False
• Depends on project size
• Uncertain

Secure software protects against:

• Unauthorized access and data corruption
• System crashes and hardware failures
• Slow performance and bugs
• Outdated libraries and dependencies
