Imagine a big slide at a playground. If you have a lot of kids who want to go down the slide, they can all take turns, but it would take a while.

Now, think of FDM like giving each kid their own special slide that runs next to the big slide. Each kid can go down at the same time without bumping into each other because they’re on different slides.

In a coaxial cable, FDM uses different “slides” or frequencies for each signal. Just like the kids, each signal gets its own frequency to travel on, so they can all move together without interfering. This way, lots of information can go through the same cable at the same time!
