Information and information processes

Information is one of the basic, keyconcepts in such a science as computer science. However, there is no strict definition of it today. It can be said, for example, that: information is a collection of information about an event / process / phenomenon / environment.

In the course of studying the data we need, we subject them to various transformations, in order to use them in decision-making, training, development of behavior, and management.

Properties of information

We do not need information at all, but at a certain time, then to orient ourselves in connection with the received data and make some decisions about how to proceed further.

To assess the quality of information, such properties as utility, completeness, reliability, relevance, accessibility, ergonomics, security, intelligibility, objectivity are used.

Information and information processes

Any of our activities can be called a process of collecting and processing the received data. We perceive them through the senses, and stores and processes its brain in the process of functioning of the central nervous system.

The information process is presented as aa set of actions performed in a certain sequence, which we produce over the available data. The goal here is to get the result, then to use it somehow. Below, let's select which basic information processes exist.

Information and information processes: search

Search is a process of extractionstored information. At the same time, we can use such methods as observation, reading, live communication, viewing, listening, querying search systems, databases, etc.

Information and information processes: collection and storage

The very collection of information is not an end in itself. In order for the data to be used by us, and repeatedly, a process such as storage is necessary.

Keeping information is the way, with the help ofwhich information is distributed in time and space. It depends on the carrier, whose role can be played by a book in the library, a picture in an album, a picture in a gallery. Computer devices are not only designed to store data compactly, but also to get to them quickly.

Information and information processes: transmission

In this process, participate:

1. Sources of information are precisely those elements of the world around us, information about which we receive and subject to various transformations.

2. Consumers of information - this is you and me. We consume information and use it in our own needs.

3. A communication channel is that material carrier (technical or other device) that captures all collected data in order to convey it from the source to the consumer.

Information and information processes: processing

Before we use the information we need, they still need to be processed.

Information processing is a process that allowsget new information on the basis of what is already available. This transformation can be connected both with the content of the received data and with the form itself, in which the information is presented initially. At the last variant it is possible to speak about coding, for example, about translation of the Russian text into a foreign language.

Search in an array of the necessary information (for example,phone number in the database), its ordering (for example, scheduling, list) - all these are also manifestations of the processing process. Mathematical calculations, text correction, logical inferences (conclusions) are also examples of procedures for converting the source data to our own needs.
