Definition: Software engineering is a detailed study of engineering to the design, development and maintenance of software.Software engineering was introduced to address the issues of low-quality software projects. Quality assurance is the process of defining how software quality can be achieved and how the development organization knows that the software has the required level of quality. IEEE, in its standard 610.12-1990, defines software engineering as the application of a systematic, disciplined, which is a computable approach for the development, operation, and maintenance of software. Software subsists of carefully-organized instructions and code written by developers on any of various particular computer languages.
