Informatics is the science of information. As an academic field it involves the practice of information processing, and the engineering of information systems. It studies the structure, algorithms, behaviour, and interactions of natural and artificial systems which store, process, access, and communicate information. The field considers the interaction between humans and information systems alongside the construction of computer interfaces. It also develops its own conceptual and theoretical foundations and utilizes foundations developed in other fields. As such, the field of informatics has great breadth and encompasses many individual specialisations including the more particular discipline of computing science. Since the advent of computers, individuals and organizations increasingly process information digitally. This has led to the study of informatics with computational, mathematical, biological, cognitive and social aspects, including study of the social impact of information technologies.
