The 23rd Olympic games were held at Los Angeles in the Unites States and, like every other Olympic Game, they represented a contest of mind, muscle, and athletic determination. The sue of high technology, however, showed more and more increasing significance in the staging of the event and helped to set an example for staging future events. The Olympic Games are not just a race of the gold anymore; they have also become a race for computer technology. For example, in this event, computers were used to keep track of schedules, accounts, transportation, and ticketing for more than 43 000 Olympic employees and volunteers. This was not an easy task. A sophisticated electronic message system, moreover, helped to keep the 12 000 or so journalists up-to-date on results. Due to this system, they were able to know about and broadcast to the world the judges’ final decision usually within a minute’s time. This message system also allowed traffic controllers to relay traffic reports more efficiently, so that the usually chaotic Los Angeles highways became easy to navigate through, computers and other high-tech tools were also used to train American athletes by analyzing and evaluating performances. This computer wizardry assisted the athletes in identifying weaknesses and suggesting ways to improve.
