Computers are tremendously important in a variety of ways. For example, they simplify many difficult or time consuming tasks to an extraordinary degree. They provide businesses, Government, individuals and institutions with an efficient way to manage large amounts of information. Computers also help people understand things better by allowing them to make models and test theories.
The value of computers lies in their ability to perform certain basic tasks include (1.) solving numerical problems (2.) Storing and retrieving information and (3.) creating and displaying documents and pictures.
SOLVING NUMERICAL PROBLEMS. One of the most important and most difficult jobs performed by computers is the solution of complicated problems involving numbers. Computers can solve such problems amazingly quickly. In many cases, the solutions show how certain things work, behave, or happen.
Storing and retrieving information. A computer can search a huge database quickly to find a specific piece of information. In addition, the information can be changed easily and quickly often in less than a second.
In economics and finance, computers solve equations to make predictions about money. Many of the equations that economists and business people use to make long range predictions are extremely complicated. But some of the most widely used of all computer programs rely on fairly simple equations. Such programs rely on fairly simple equations. Such programs help people and businesses work out their taxes, create budgets and calculate the value of their investments.
