MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines.

Detailed explanation-2: -The selection of a particular input data line for the output is decided on the basis of selection lines. The multiplexer is often called as data selector since it selects only one of many data inputs.

Detailed explanation-3: -The names ‘data selector’ and ‘multiplexer’ are commonly interchanged, with multiplexers called data selectors and vice versa.

Detailed explanation-4: -Explanation: A digital multiplexer is a combinational circuit that selects one digital information from several sources and transmits the selected information on a single output line depending on the status of the select lines. That is why it is also known as a data selector.

Detailed explanation-5: -An alternative name of the multiplexer is MUX or data selector. A demultiplexer uses one input signal and generates many. So it is known as Demux or data distributor.
