B) Wi-Fi is faster than 4G.
C) Wi-Fi's range is farther than 4G.
D) Wi-Fi operates in the unlicensed public 2.4-GHz spectrum.

Accepted Answer

Wi-Fi typically has a shorter range compared to 4G networks. 4G, being a cellular network technology, is designed to cover large geographical areas, whereas Wi-Fi is intended for local area networking and thus has a more limited range.

Question 2

NLUI stands for:
A) negative lumens ultraviolet imaging
B) natural language user interface
C) nonlinear launcher utility
D) national laborers urbanization industry

Accepted Answer

NLUI stands for natural language user interface, which is a type of interface that allows users to interact with technology using natural language, such as spoken or written conversation, instead of traditional input methods like keyboard or mouse. A, C, and D are not relevant or accurate descriptors for NLUI.
