ユーザーは SOHO PC 用のウイルス対策ソフトウェアを入手したいと考えています。技術者はライセンス付きソフトウェア製品を推奨しますが、ユーザーはライセンス料を支払いたくありません。技術者が推奨するライセンスの種類は次のうちどれですか?
正解:B
Open-source software is software that has its source code available for anyone to inspect, modify, and distribute. Open-source software is usually free of charge and does not require a license to use. Some examples of open-source antivirus software are ClamAV, Comodo, and Immunet12. The other license types are either not free or not suitable for a SOHO PC. Corporate and enterprise licenses are designed for large-scale organizations and networks, and they usually require a subscription fee. Personal licenses are for individual users and may have limited features or support.
