Describe the classic software development cycle (SDLC).

The classic Software Development Life Cycle (SDLC) includes several stages:

1. Requirements gathering and analysis – determining what the user or business needs.
2. System design – creating architecture and technical specifications.
3. Development (coding) – writing the program code.
4. Testing – verifying functionality and compliance with requirements.
5. Deployment – deploying the system in the production environment.
6. Maintenance and support – fixing bugs and updating the system.

This process helps structure work and ensure the quality of the final product.
