1. What is the definition of "Digital" in the context of IoT?
A. Technologies that generate, store, and process data as continuous waveforms
B. Technologies that generate, store, and process data as fixed numbers in binary
form
C. Technologies that rely on analog signals for communication
D. Technologies that only store data without processing capabilities
Correct Answer: B
Rationale: Digital refers to technologies that generate, store, and process data as
fixed numbers represented by binary digits or bits in the form of 0's and 1's, which
is fundamental to how IoT devices operate .
