问题     In Kansas, Missouri, a computer becomes a great help to firefighters. The computer contains information about every one of the three hundred and fifty thousand street addresses in the city. When a firefighter answers a call, the computer gives him important information about the burning building. The computer can give the location of the building and its size, type and content.
    In fact, the computer system has almost unlimited ways of helping the firefighter with their problems. For example, it can give medical information about invalids living in a burning building. With this information the firefighter can take special care to find these sick persons and remove them quickly and safely.
    The speed of a computer is amazing. Within two or three seconds after a call is received, the computer provides necessary information for the firefighters. The information is then sent to them by the radio from the computer center in the city hall.
    The Kansas City Computer System also contains a medical record of each of the city’s nine hundred firefighters. This kind of information is especially useful when a firefighter is injured. With this medical information doctors of hospital can treat the injured firefighter more quickly and easily. The firefighters themselves greatly appreciate the computer’s help. They can learn about possible dangers ahead of them and can prepare for them. Many times the computer information helps to save lives and property, and sometimes the lives are those of the firefighters themselves.
