Question

Quizplus · Accepted Answer

A multiplexer is a device that combines data from multiple sources into a single output signal that carries multiple channels. This is done by dividing the high-speed digital transmission medium (such as fiber optics) into multiple channels or time slots and assigning each channel to a particular user or data stream. This allows multiple users to share a single communication line, which can save costs and increase efficiency.
