Software development is the process of designing, creating, testing, and maintaining computer programs and applications. It involves several stages, including identifying user needs, planning the software solution, designing the software architecture, coding the solution in one or more programming languages, testing the software, and maintaining it over time.

Software developers use programming languages, frameworks, and tools to create software that meets user needs and requirements. Some development processes are more structured, such as the Waterfall model, while others, like Agile development, prioritize flexibility and adaptability throughout the development cycle. Software development is an interdisciplinary field that involves skills in programming, design, testing, and project management.
