Processing input in sense organs; it is expressed as the cognitive term 'to the body of functions for perceiving and understanding the world. The cognitive system directs information to process and evaluate it into the cortex. Cognitive systems are a set of techniques that can independently develop solutions and strategies for their tasks on human beings. To do this, they are equipped with cognitive skills to understand context, interact, adapt and learn. Cognitive systems can use artificial intelligence methods such as machine learning, neural networks, and deep learning. However, cognitive systems should not be equated with artificial intelligence. One of the possible definitions of artificial intelligence refers to cognitive processes and especially to reasoning. Intelligence is the ability of people to think abstractly, logically, and derive purposeful action. Artificial intelligence is the application of thinking and intelligent behavior in machines. In the research, as a way of data collection, "document scanning-literature scanning" method was used. In this direction, cognition, cognitive (cognitive) system, artificial intelligence and human relations were examined. As a result of the study, the functioning of the controlled system was examined, where the increasing similarities between human and artificial intelligence draw attention.
