FIPS 201-3 under Component

  Member of a set of elements that constitute a system. Note 1: A system element can be a discrete component, product, service, subsystem, system, infrastructure, or enterprise. Note 2: Each element of the system is implemented to fulfill specified requirements. Note 3: The recursive nature of the term allows the term system to apply equally when referring to a discrete component or to a large, complex, geographically distributed system-of-systems. Note 4: System elements are implemented by: hardware, software, and firmware that perform operations on data/information; physical structures, devices, and components in the environment of operation; and the people, processes, and procedures for operating, sustaining, and supporting the system elements.
