Software Development Lifecycle

The Software Development Lifecycle (SDLC) is a structured process that guides how software is created and maintained. It typically includes several key stages: **planning** (defining what the software needs to do), **design** (planning how it will work), **development** (writing the actual code), **testing** (checking for errors and ensuring it meets requirements), **deployment** (making it available to users), and **maintenance** (updating and fixing issues post-launch). This cycle helps ensure that software is reliable, efficient, and meets the users' needs throughout its life.
