Software development is a comprehensive process that starts with an idea and extends to the ongoing maintenance of software applications or systems. It involves designing, writing, and managing source code—the detailed instructions that enable computers to perform specific tasks. This process can range from building new software from the ground up to refining and maintaining existing systems to ensure they operate smoothly and efficiently. In today’s digital age, software development is crucial for creating the technologies that power businesses, enhance productivity, and improve user experiences, making it the backbone of modern digital infrastructure and innovation.
