A system, in a general scientific or engineering context, refers to a set of interacting or interdependent components organized to achieve a defined objective. Analyzing a system requires viewing the components not in isolation, but in relation to how they function as a cohesive, integrated whole. Systems can be classified broadly, such as biological, where the internal mechanisms of life maintain homeostasis; mechanical, involving physical linkages and power transfer; or informational, encompassing the flow and processing of data. Central to the study of systems is understanding the relationship between input, process, and output, often modeled through feedback loops that allow the system to regulate itself and adjust to changes within its operational environment, thereby maintaining stability or executing complex functions.
