Question

Which combinational circuit is renowned for selecting a single input from multiple inputs & directing the binary information to output line?

(a) Data Selector

(b) Data distributor

(c) Both data selector and data distributor

(d) DeMultiplexer

The question was posed to me in an interview for internship.

This intriguing question originated from Multiplexers (Data Selectors) in section Combinational Circuits of Digital Circuits

Answer 1

Right answer is (a) Data Selector

The best explanation: Data Selector is another name of Multiplexer. A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines.
