Computers have touched almost every job in the work environment. Most office personnel work with computers in word processing or spread sheet applications. Many workers are entering data into the computer and retrieving data from the computer continually. These people can be taking orders, billing customers, keeping a current inventory, or performing hundreds of other routine tasks. Doctors are using computers to diagnose illnesses. Engineers are using computers to draft specifications using all types of graphics. Managers at all levels are using computer reports to help them make intelligent, informed business decisions. The computer has left its mark on every major field of employment, and the computer is still in its infancy. The gains to the business from using a computer are many. The primary gain is in the money saved through computer use. By using the computer, the business can almost do away with paper files. This will increase productivity because the computer can process data more rapidly and store data more efficiently in a limited amount of space. The rapid processing saves money in that the computer increases the timeliness and accuracy of the worker. Getting reports to the decision makers faster can only increase profits and make the work place run more efficiently. The computer has done much to improve the lives of people. It has improved services and lessened the margin of error in most areas of life today. The computer has been one of the greatest influences on the modern world.
