Introduction to Software Engineering
Software engineering is a branch of engineering concerned with the design, development, testing, and maintenance of software systems. It involves applying engineering principles to create high-quality software in a systematic, disciplined, and cost-effective manner. The field has emerged due to the increasing complexity of software applications and the need for reliable, maintainable, and scalable solutions.
