There are 66 <strong>in</strong>dividual m<strong>in</strong>erals that contribute to the typical computer that are identified above. There are others, <strong>in</strong> addition to those listed<br />
above, but it should be evident that without many m<strong>in</strong>erals, there would be no computers, or televisions, for that matter.<br />
