Computers have a positive effect on society by providing immediate access to information regarding most areas of human endeavor. Computers are beneficial in areas such as business transactions and record keeping, science and medicine, education, communications, transportation and entertainment.
Computers run weather simulations for forecasting, analyze and store large, complex sets of data and help physicians monitor and diagnose patients. Computers are crucial to the anti-lock brakes that are a safety feature in vehicles. Consumers can buy movie and airline tickets, check political polls or sports scores, and research different brands of new cars from a smart phone, tablet, laptop or other computer. By taking on small, repetitive tasks, computers have freed up time for more important work. Computers process millions of records in seconds, improving reliability and accuracy for all types of data.
