Coaxial cable

Okay kiddo, have you ever seen a tube of toothpaste? Imagine that tube being hollow and long, like a straw. That's what a coaxial cable basically looks like.

Now let's break down what's inside that toothpaste tube. There are two main parts: the core and the insulation. The core is a tiny wire that runs right down the middle of the cable. The insulation is a layer of material that wraps around the core like a cozy blanket.

But hold on, we're not done yet! There's also another layer of wire surrounding the insulation called the shield. This layer is like a protective armor that helps to prevent interference from other electronic devices.

So in summary, a coaxial cable is a long tube-like cable that has a tiny wire (the core) running down the middle, surrounded by insulation and then a shield to protect it from interference. This cable is used to transmit signals between electronic devices, like a TV and a cable box.
