available as needed Moore s Law processing performance of transistors on chips will double every 18 months Multi core Microprocessors single computing component with two or more CPUs most new computers and laptops have multi core Can run older software written for single brain chips E Waste discarded electronic devices typically just sits around in landfills or is shipped overseas When e waste just sits around it sends off dangerous toxins into the air and can be deadly Moore s Law means faster and newer technology meaning more e waste from the old systems DISRUPTIVE TECHNOLOGY
