Information is one of the basic, key concepts in a science such as computer science. However, there is no strict definition of it today. We can say, for example, as follows: 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 certain transformations so that we can use them in the form we need for decision-making, training, development of behavior, and management.
Information Properties
We do not need information at all, but at a certain time, in order to then navigate in connection with the data received and make some decisions about how to proceed.
To assess the quality of information, such properties as usefulness, completeness, reliability, relevance, accessibility, ergonomics, security, intelligibility, objectivity are used.
Information and information processes
Any of our activities can be called the process of collecting and processing the data obtained. We perceive them through the senses, and stores and processes its brain during the functioning of the central nervous system.
The information process is presented as a set of actions performed in a certain sequence that we perform on the available data. The goal here is to get the result so that you can use it somehow. Below we highlight what are the main information processes.
Information and information processes: search
Search is the process of retrieving stored information. At the same time, we can use such methods as observation, reading, live communication, viewing, listening, querying search engines , databases, etc.
Information and information processes: collection and storage
The collection of information itself is not an end in itself. In order for the data obtained to be usable, more than once, a process such as storage is needed.
Information storage is the way in which information is distributed in time and space. It depends on the medium, the role of which can be played by a book in the library, a picture in the album, a picture in the gallery. Computer devices are designed not only to store data compactly, but also in order to get quick access to them.
Information and information processes: transmission
This process involves:
1. Sources of information are precisely those elements of the world around us that we receive information about and subject to various transformations.
2. Consumers of information - this is us. We consume and use information in our needs.
3. A communication channel is that material medium (technical or other device) that captures all the collected data in order to convey it from the source to the consumer.
Information and information processes: processing
Before you use the information we need, they still need to be processed.
Information processing is a process that allows you to obtain new information based on existing information. This transformation may be related both to the content of the obtained data, and to the form itself in which the information is presented initially. With the latter option, we can talk about coding, for example, the translation of Russian text into a foreign language.
Search in the array of the necessary information (for example, a telephone number in the database), its ordering (for example, scheduling, list) - these are also manifestations of the processing process. Mathematical calculations, text correction, logical conclusions (conclusions) are also examples of procedures for converting source data to our own needs.
