Every day, people use computers in new ways. PC is still available, as they strengthen their information resources, and easier to use.

Computers in Business One of the earliest and largest applications of computers is the protection and management of business and financial statements. Most large companies keep records of the work of all employees in databases run by large computer programs. Similar programs and databases used in business functions such as customer billing address, payment received and tracking of payments made and actions to follow the necessary materials and products produced, stored, transferred and sold. In fact, do almost all of the information society, business, including computer and information technology.

Small scale, many companies have replaced meters with point of sale (POS) terminals. These POS terminals not only print a receipt for the customer, but also to send information in a computer database when each item sold for maintaining the list of products and goods contracts in hand. Computers are also very important in modern factories. Computer robots now do tasks that are hot, heavy or dangerous. And robots are used to routine, repetitive tasks where fatigue or boredom can lead to poor performance.

Computers in medicine, information technology plays an important role in medicine. For example, a scanner, a series of photos of the body of information axial tomography (CAT) or magnetic resonance imaging (MRI). A computer then combines the images to produce detailed images of three-dimensional body organs. In addition, MRI produces images that show changes in body chemistry and circulation.

Computers in science and technology using supercomputers, meteorologists predict future weather using a combination of weather observations from many sources, mathematical representation of behavior of the atmosphere and geographical data.

Automation of design and production of computer programs, often called CAD / CAM has led to improved products in many areas, especially when models are very detailed. allow software engineers to analyze models of complex structures such as power plants and space stations
