Question

Name of the device that selects between several analog or digital input signals and forwards the selected input to a single output line:

• A. Modulator
• B. Router
• C. LAN
• D. Multiplexer

Hint:

A multiplexer allows multiple input signals to share one output line by selecting one at a time based on control signals.

Answer 1

The Correct Option is D

Step 1: Multiplexer Functionality
A multiplexer (MUX) chooses one of several input signals and directs it to a single output. This process merges multiple inputs into a single output stream for transmission or processing.
Step 2: Summary
Therefore, a multiplexer is the component that selects and forwards one of multiple input signals.
Final Answer: \[ \boxed{\text{Multiplexer}}\]
