subsystem
Definitions
| Type | Definition | Sources |
|---|---|---|
| Asset | A collection of interacting hardware, software, and human components. In particular, a subsystem is a secondary or subordinate system, usually capable of operating independently of, or asynchronously with, a controlling system. A subsystem is analogous to a subdirectory in a file system which contains files and other subdirectories. Subsystems are often organized physically (e.g.,, a building that contains floors, each of which contains rooms) or functionally (e.g.,, a process that contains stamping stations, the conveyor system, and inspection stations). A single device can appear in multiple subsystems. The authority documents also define several categories of subsystems. (used 41 times in citations and controls) |
