What does "open-source software" mean?

The definition of "open-source software" centers around the idea that the source code of the software is publicly accessible. This availability allows anyone to view, modify, and distribute the software, fostering a collaborative environment for development and innovation. The essence of open-source software is rooted in community involvement and transparency, which leads to continuous improvements and bug fixes by a wide range of contributors.

The option states that the software is not only available for use but also modifiable, which is a fundamental characteristic that distinguishes open-source from other types of software. This flexibility encourages users to adapt the software to meet their specific needs, enhancing its utility and relevance across various applications. As a result, open-source software has become integral to many aspects of technology development, providing significant advantages like lower costs, increased security through community scrutiny, and the rapid evolution of ideas and functionalities.
