The home puter industry has been growing rapidly in the United States in the last ten years. Computers used to be large, expensive machines that were very difficult to use. But scientists and technicians have been making them smaller and cheaper while at the same time they have been made easier to use. As a result, their popularity has been increasing as more people have been buying puters for their homes and businesses.
Computers have been designed to store information and pute problems that are difficult for human beings to work out. Some have voices that speak to their operators. Stores use puters to keep records of their inventories and to send bills to their customers. Offices use puters to copy letters, record business and keep in touch with other offices. People also use puters in their homes to keep track of the money they spend.
