Conversation

I was reading about how a multiplexor works in data transmission.

Oh really? I've heard that term before but I'm not quite sure what it means.

It's basically a device that combines multiple signals into one signal.

That makes sense! It sounds really useful for reducing the number of connections.

Root Explanation

Multiplexor → It is formed from "multi-" (meaning many) and "plex" (from Latin "plicare", meaning to fold). The word "multiplexor" refers to a device that folds multiple signals into one, allowing many inputs to be sent over a single channel.

Memory Tip

Think of 'many' ('multi-') being 'folded' ('plex') together — that's how a multiplexor combines multiple signals.
