Shielding has to do with the orientation of the ground wire in the cable versus the signal wire. In a shielded cable the ground wire completely surrounds the signal wire like a pipe. In an unshielded cable the ground wire is wrapped around the signal wire or run next to it.

Cables that are shielded like this are coaxial.
