Text D: Categories of information-processing tasks

As we have already learnt, companies and businesses use Information Technology (IT) to do information-processing tasks. These tasks range from computing and printing checks to creating the site from which customers can order products. Because IT is a set of tools for working with information, we can easily categorize different IT tools according to what information-processing tasks we have to perform. In general, there are five categories of information-processing tasks:

-Obtaining information. We get information at its point of origin by using different input devices, such as mouse, keyboard.

-Conveying information. The information is presented in its most useful form with the help of screen, printer and other output and display devices.

-Creating information. We process information using, for example, word processing software.

- Storing information. Using different storage technologies, the information is stored for use at a later time.

-Communicating information. We send information to other people or to another location with the help of telecommunication technologies.

It’s possible to look at each of these information-processing tasks separately but finally we’ll have to combine them to create a system that performs all the tasks. Performing of any particular task-- finance, marketing and management -- always involves these five information-processing tasks.
