Isolated means far away from everyone or everything else. The hermit who lives on a remote island is isolated from the rest of the world, with nothing but coconuts and fish to keep him company.
The word isolated comes from the Latin word insula, which means island. You don't have to be on a remote island to feel isolated, though.
