A sample from this course

One topic, as StudyPath teaches it.

Systems and information systems

This topic introduces the meaning of a system and explains how information systems are organised to collect, process, store and distribute information. For exams, you must clearly distinguish system elements, system types, and the components and functions of an information system, because these ideas are the foundation for understanding how computer-based organisations operate.
