1. Software Development Overview

• Software:
  • Beyond code; includes executable code, libraries, and documentation.
  • A program serves a computational purpose; a software product meets specific requirements.
• Software Engineering:
  • Applies scientific principles, methods, and procedures to develop reliable, efficient software.
  • Uses systematic, disciplined, quantifiable approaches for development, operation, and maintenance.
• Importance:
  • Enables timely creation of complex systems.
  • Ensures software reliability and efficiency on real machines.

2. Types of Software

• Operating Systems/System Utilities: Manages hardware (e.g., Windows, Linux utilities).
• Application Software: End-user tools (e.g., MS Office, Adobe Photoshop).
• Engineering/Scientific Software: Technical tools (e.g., MATLAB, CAD).
• Embedded Software: Hardware-specific (e.g., IoT, automotive).
• AI Software: Machine learning, robotics, AI applications.
• Legacy Software: Older, still-used applications.
• Web/Mobile Software: Websites and mobile apps.

3. Characteristics of Good Software

• Operational (Non-Functional):
  • Budget: Developed within financial limits.
  • Usability: User-friendly (intuitive UI, accessibility).
  • Efficiency: Optimizes storage and performance.
  • Correctness: Bug-free, delivers required functionalities.
  • Functionality: Meets all user needs.
  • Dependability: Includes necessary libraries/configurations.
  • Security: Protects data from threats.
  • Safety: Non-hazardous to users/environment.
• Transitional: Easy to adapt to new environments.
• Maintenance: Simple to update and fix.

4. DevOps

• Why It Matters:
  • Improves collaboration, delivery speed, and quality.
  • Median salary referenced but not specified (career benefit implied).
• Prerequisites:
  • Basic Linux knowledge.
  • Familiarity with development platforms.
  • Programming skills (JavaScript/Java preferred).
  • Willingness to learn new technologies.

5. Scrum Framework (Agile Methodology)
