In Kansas City, Missouri, a computer helps fire-fighters.The computer contains information about every one of the 35000 street addresses in the city.When fire-fighters answer a call, the computer will give them important information about the burning building's position, size, type, and so on.In fact, the computer system(系统)has almost all the ways of helping fire-fighters with the problems facing them.For example, it can give medical information-about invalids living in a burning building.With this information, the fire-fighters can take special care to find these sick persons and carry them away quickly and safely.
The Kansas City computer system also keeps a medical record of each of the city's 9000 fire-fighters.This kind of information is especially useful when a fireman is injured.With this information, doctors at the hospital can treat the injured fire-fighters more quickly and easily.
