What term refers to wired and wireless communication between similar devices?

• A. Mass production
• B. Lamination
• C. Mass customization
• D. Machine to machine (M2M)

Answer: (D)

The main idea is automated communication between devices of the same type. Machine-to-machine communication involves devices exchanging data over wired or wireless networks without human involvement, enabling things like sensors sending readings, meters transmitting usage data, or controllers coordinating equipment. This directly captures the notion of similar devices talking to each other across different connection methods.

The other terms describe manufacturing or production concepts rather than device-to-device data exchange. Mass production is about producing large quantities of identical items, lamination is a material layering process, and mass customization refers to making customized items at scale. None of these focus on how devices communicate with each other.
