The technology and sophistication of electronics has exploded.

Digital cameras on cell phones and the Internet have affected

everyone. It was not many years ago that a cell phone was a luxury;

today it is becoming a necessity. The Internet has become part of the

majority of households. Preschool children can operate personal

computers and grandparents send messages and JPEG pictures

over the Internet. Online purchasing and banking have become bigtime

businesses, seriously impacting brick and mortar stores’ sales.

These enhancements and advantages in technology have been a

benefit to our society by providing more capabilities, more automation,

and less physical effort to accomplish a task at a reasonable

cost. A microwave oven is the appliance of choice for most families

today. Technology has impacted all aspects of our work and play.
