Software engineering is a field within computer science focused on designing, developing, testing, and maintaining of software applications.It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
While less common than commercial proprietary software, free and open-source software may also be commercial software in the free and open-source software (FOSS) domain. But unlike the proprietary model, commercialization is achieved in the FOSS commercialization model without limiting the users in their capability to share, reuse and duplicate software freely.
