オープンソース
誰でも閲覧、変更、配布できるソースコードを持つソフトウェア。
Open Source software promotes collaboration and transparency. Anyone can view the code, report bugs, or contribute improvements. Famous examples include Linux, Bitcoin, and Python. Licensing terms (like MIT, GPL, Apache) define how the code can be used and shared. It contrasts with proprietary (closed source) software.
