Data is raw facts and figures. They have no meaning. For e.g. 559873 is data. We cannot say what this number is. It can be your library number, a product number

Signal is an electric current used to convey data from one place to another. For e.g. If you want to call someone, over the telephone line there will be signals sent to connect to the other phone.
