In systems terminology, a subsystem is defined as what?

• A. A part of a larger system that functions together
• B. A separate organization entirely
• C. An external supplier
• D. A complete system in itself

Answer: (D)

A subsystem is a part of a larger system that functions together. In systems thinking, a system is made up of interrelated parts that work toward a common purpose; a subsystem has its own role and processes but operates within the context of the whole, contributing to and depending on the other parts. It isn’t a separate organization, nor an external supplier, nor a standalone unit. A complete system in itself would operate independently, not as a component inside another system. For example, the braking system of a car is a subsystem of the vehicle, and the memory management component in a computer is a subsystem of the computer system.
