Software Development

1. Software Engineering

SDLC (Software Development Life Cycle):
- Framework for developing software applications systematically.
- Stages: Requirements Analysis → Design → Implementation → Testing → Deployment → Maintenance.

Development Models:
- Waterfall Model: Sequential approach; suitable for well-defined projects.
- Agile Methodology: Iterative approach emphasizing flexibility and collaboration (e.g., Scrum, Kanban).
Software Testing:
- Ensures software quality and correctness.
- Types: Unit Testing, Integration Testing, System Testing, Acceptance Testing.

2. Version Control

Git:
- Distributed version control system for tracking changes in code.
- Commands:
  Code: Select all
```
git init
```
  ,
  Code: Select all
```
git add
```
  ,
  Code: Select all
```
git commit
```
  ,
  Code: Select all
```
git push
```
  ,
  Code: Select all
```
git merge
```
  .
GitHub/GitLab/Bitbucket:
- Hosting platforms for collaborative code management.
- Used for pull requests, code reviews, and continuous integration.

3. Design Patterns

Reusable solutions for common software design problems.
- Singleton: Ensures only one instance of a class exists.
- Factory: Creates objects without specifying the exact class.
- Observer: Manages one-to-many dependency relationships.
- Model-View-Controller (MVC): Separates data, user interface, and control logic.

4. Web Development

Frontend Development:
- Technologies: HTML, CSS, JavaScript.
- Frameworks: React, Angular, Vue.js.
- Concepts: Responsive Design, Web Accessibility, DOM Manipulation.
Backend Development:
- Server-side programming: Node.js, Django, Flask, Ruby on Rails.
- RESTful APIs: HTTP methods (GET, POST, PUT, DELETE).
- Authentication: OAuth, JWT, Session-based authentication.
Full-Stack Development:
- Combining frontend and backend development.
- Frameworks: MERN (MongoDB, Express, React, Node.js), MEAN (Angular instead of React).

5. Mobile App Development
