A computer chip is a tiny wafer of semiconducting material with an embedded electronic circuit. It contains millions of microscopic electronic components called transistors that transmit data signals. Initially, chips were physically large, and computing was only something done in national labs, universities, or large companies. Further innovation in computer chip technology resulted in the development of high-performance processors that power all types of advanced analytics, graphics, and machine learning applications. As the size of the computer chip reduced, it became possible to create smaller computers that could be used at home. Today, the computer chip is omnipresent in our lives—in everything from our microwaves to our toothbrushes. Computer chips are typically manufactured in factories called fabrication plants or fabs.
