A Computer-Based Information System (CBIS) combines people, hardware, software, telecommunications, and data to collect, process, and disseminate information to support decision-making. Key components include input, processing, and output activities, as well as considerations of security, privacy, and ethical issues in the realm of information systems. Organizations rely on unique cultures and established procedures to effectively manage and utilize information systems.
