In many contexts, a collection of components arranged to perform a defined set of tasks is called a what?

• A. Cell
• B. System
• C. Network
• D. Subsystem

Answer: (B)

A system is a collection of components arranged to work together to achieve a defined set of tasks. This emphasizes that the parts are integrated to function as a single unit, processing inputs and producing outputs toward a common goal. In biology and many contexts, you see whole bodies or organs described as systems because they coordinate multiple parts to perform necessary functions, like the circulatory system moving blood through the body. A cell is the basic unit of life, not a collection of multiple parts working together as a unit. A network focuses on how components are connected and communicate, rather than on them functioning as a single processing unit. A subsystem is a smaller system within a larger system, whereas the term described here refers to the entire collection acting as one unit.
