What is the primary characteristic of most software according to the software development paradigm?
- Most software is custom-built rather than assembled from existing components. (correct)
- Most software is fabricated from standard components.
- Most software is generated automatically with little human input.
- Most software relies on existing software frameworks.
Which statement best describes the nature of software engineering?
Which statement best describes the nature of software engineering?
- Software development is strictly automated and requires no engineering skills.
- Software is developed or engineered, not manufactured in the classical sense. (correct)
- Software is purely a manufacturing process.
- Software engineering focuses solely on assembling existing components.

Study Notes
Software Overview
- Software engineering is about building and maintaining software systems.
Definitions
- Software is a set of instructions and data that tells a computer what to do.
- Software engineering is the application of engineering principles to the design and development of software.
Software Evolution
- Software systems evolve over time as their requirements change.
Software Evolution Laws
- Brooks’ Law: Adding more programmers to a late project makes it later.
- Second System Effect: Over-engineered, overly ambitious second systems fail to adequately address requirements.
- Law of Continuing Change: Software systems will continue to change for as long as they are in use.
E-Type Software Evolution
- E-type software evolution involves evolutionary changes to existing software systems.
E-Type Software Evolution
- E-type software evolution involves evolutionary changes to existing software systems.
Software Paradigms
- There are different paradigms for developing software, such as object-oriented programming, and agile methodologies.
Software Development Paradigm
- A software development paradigm defines the way software is developed.
Need of Software Engineering
- Software is complex and requires a systematic approach to development.
- Software projects often fail to meet their goals.
Software Does Not Wear Out
- Software does not wear out like physical systems.
Maintenance
- Software requires ongoing maintenance to fix bugs, improve performance, and adapt to new requirements.
- According to studies, more than 70% of the software lifecycle costs are spent on maintenance.
Software Characteristics
- Software is typically custom-built, not assembled from existing components.
- However, reusable components are becoming increasingly popular for building new software applications.
- Modern reusable components can encapsulate both data and processing, making software development more efficient.
- Examples of reusable components include GUI libraries which enable the creation of user interfaces for applications.
- Software is developed or engineered, rather than manufactured in the traditional sense.
