Computers can be even used for business. In the area of the stock market, one could use the program Stocktrax, which displays opening and closing rates of stocks, changes in the stock from day to day, and trends of the stock over a period of time. Computers also, on the subject of the stock market, could be a source of buying stocks as well as selling. The key to this is a modem. You could call the New York Stock Exchange's Bulletin Board Service (also called a BBS) and make your transactions there, and they would be recorded. This would take less time than yelling and screaming at other people on the premises.

Computers are already in use in facilities where a teenager could take a driver's permit test. By using a touch sensitive screen, a person gets a question, which is usually multiple choice. Every time a question is answered, right or wrong, the result is recorded. This could be a possible new solution for test taking in classes if enough computers were available.
