Which term refers to an object placed into orbit by humans; most are used for communications purposes?

• A. CAD
• B. CAM
• C. Satellite
• D. GPS

Answer: (C)

Satellites are objects placed into orbit by humans. Once in orbit, many are used to relay communications signals, enabling television, phone, and data services around the world. The other terms refer to different ideas: CAD is computer-aided design software for creating designs, CAM is computer-aided manufacturing software for controlling machines, and GPS is a navigation system that uses satellites but is not the object itself. So the best match for an object humans put into orbit, commonly used for communications, is satellite.
