The answer is a compact disc.
Optical storage devices use laser technology to 'read' the data stored. A CD converts the data(music, video etc) into a long list of binary code. This binary code is stored through 'land' and 'pits'. Pits or bumps are small holes that are made through a laser onto the CD. They represent the zero of the binary code. The land is the unchanged part of the CD ...

Sulphur has an electronic configuration of [Ne] 3s2 2p4. It has 4 electrons in the 4p shell. Sulfide ion is formed at the lowest oxidation state that sulfur can achieve. Since losing 4 electrons requires a lot of energy sulfur will gain the 2 electrons in the 4p shell and will have a valency of -2.
Hence, the typical oxidation number of the sulfide ion is -2.
