4. This material did revolutionize how technology is made superconductor insulator conductor semiconductor

## Step 1<br />The question is asking which material revolutionized the way technology is made. The options provided are superconductor, insulator, conductor, and semiconductor.<br /><br />## Step 2<br />Semiconductors are materials that have properties between conductors and insulators. They are not as good at conducting electricity as conductors, but they are not as poor at conducting electricity as insulators.<br /><br />## Step 3<br />Semiconductors are crucial in the production of electronic devices such as transistors and diodes. These devices are the foundation of modern electronics, which is why semiconductors are considered to have revolutionized technology.
