📘 Lecture 2: Software Development Life Cycle (SDLC) Explained | Design, Development, Testing & More
Welcome to Lecture 2 of Computer Science Class 11 Course! In this exciting video, we dive deep into one of the most important concepts in software engineering — the Software Development Life Cycle (SDLC). Whether you're a beginner or brushing up your basics, this video will give you a clear and practical understanding of how real-world software is planned, built, and maintained.
🔍 Topics Covered:
✅ Design Phase – Learn how software is planned just like blueprints for a house. Understand flowcharts, models, user interfaces, architecture, and requirement specifications.
✅ Development Phase – See how the actual coding begins, and how programmers translate design into functioning software – just like following a recipe!
✅ Testing Phase – Explore how developers test software for bugs, errors, and performance issues to ensure quality.
✅ Deployment Phase – Discover how software is installed, configured, and tested in real-world environments.
✅ Maintenance Phase – Understand the importance of updates and ongoing support after software is released.
✅ Introduction to Software Methodologies – Learn why structured approaches like SDLC are essential.
✅ Waterfall Model – Get a clear explanation of this linear model, with its phases, benefits, and limitations.
