What is information processing?

In the most general sense, information processingis the solution of an information problem. Each of us once studied math at school. It will help you to understand what will be discussed later. Consider an elementary mathematical problem: students of class "A" collected two tons of waste paper, and students of class "B" - half a ton less. How many scrap paper did the students of both classes collect?

It seems that it is pointless to call the right answer.

In the above problem, we have a certain setsource data. On their basis, it is required to obtain a concrete result. Actually, the transition from the first to the second - this is the processing of information in its pure form. Notice, you just processed a certain amount of it during the solution. Therefore, there is every reason to say that you are a performer. Obviously, they can be not only a person, but numerous information processing devices, of which there are many around. Their brightest representative is a usual personal computer.

What else is characterized by the result?And it is characterized by the fact that it was possible to obtain new data. Which previously had no honor to exist or were not designated as the source code. This was due to their (data) transformation, carried out in full accordance with certain rules and algorithms.

In the course of solving information-type problemsit is necessary to deal with processing, which is aimed at changing the form in which the initial data were submitted. This is typical for the following processes: systematization, search, coding.

For yourself, remember that processing information can be treated in two ways. Either as a solution to any information problem, or as a transition from the initial information to a certain result.

Следовательно, обработка информации может быть two kinds. The first is related to the process of obtaining any new content. The second one is connected with the change in the form of the received data, which, however, does not in any way change their content.

Now let's talk about one of thevarieties of the phenomenon under consideration, which is called "processing graphic information." Obviously, special technologies are required to work with such data.

In general, this kind of informationis represented by all kinds of images, diagrams, graphs, sketches and so on. And when we are talking about special technologies, we can not say about specialized input devices of this type. To this class of devices can be attributed to the usual keyboard and mouse, graphic tablet, scanner. Each of these means has its own advantages. The only thing that unites them is the convenience of using them in their work. To perform the required operations with the images you have entered, you will need special software - graphic editors. Fortunately, today they have a number. And choose this or that program should not only in accordance with the level of training, but also with an eye on the functional. It is clear that the acquisition of a powerful editor for working with elementary diagrams is not a rational solution.
