Methods, types of information, computer, storage and processing
The concept, which will be discussed, is widespread in our everyday life. Information - the word capacious, refers to the general scientific categories and is important in different sciences.
The very word came to us from Latin and intranslation it sounds like informing. In fact, this concept is abstract and has several meanings that depend specifically on something that determines the types of information. But all the same, the meaning of the word is that it is, first of all, a set of specific information, preserved and disseminated. And they, in turn, determine knowledge that is always expressed in different forms. They surround a person always and everywhere, because without this the existence of life itself is impossible.
Various types of information are found everywhere. We all know that only the apple tree will grow from the seed of the apple tree and nothing more. This is genetically embedded in the tree, and nothing can be changed. Air is the source of information for all trees (and not only): according to its condition, trees can determine the time when it is necessary to awaken to life. And take the migratory birds. The flock flies only by a certain route, which is set in their genes, and it is not possible to turn off from it for them.
Man at all times has sought not onlyKeep and fix the types and properties of information, but also share it with others. For this purpose, various types of information technologies have been created in the modern world, as reliable means of collecting, processing, storing and transmitting it to other generations.
In the modern world, this definition on presentation, storage and coding method is divided into the following types of information:
- graphic (sometimes expressed in visual means);
- sound;
- Text;
- numeric;
- Video information.
The first specified type of information exists indrawings, pictures, photographs, diagrams, drawings. Known already since the appearance of the first representatives of the future society. Sound information is expressed in sounds. This is also quite an ancient definition. Text is the way to designate speech with symbols, that is, letters. It is analogous to it: the coding of information with the help of numbers. The latest invention in the modern world has become video information - a way of storing and transmitting "live" pictures of the world. In addition to all the types of information described, there is still tactile perception (sensations, smells, tastes, etc.)
Any types of information require ways tostorage and transmission, especially over long distances. First, light signals were used for this, then radio waves. Since the advent of computers, storing and transferring any information has become much easier. The information can be stored on various types of electronic media: magnetic disks, laser discs, special storage devices, such as a flash card. Every day new methods and devices appear. Any concept of information, types of information is handled without problems by the computer. Processing includes playback, transmission, conversion, data recording. To do this, you only need to be able to use the computer and specially designed for such actions programs.
And, of course, the basic information of our timeis represented in the global Internet. The methods of storage and transmission here are somewhat different from the familiar and familiar to man. Since its volumes on the Internet are very large, then the ways of working with it are special. The software is updated every day, which makes it possible to work with such information collectively and continuously.
Properties
Information, as we have said, is a concreteobject, and like all of them, it has certain properties that can be listed for a long time. Let us dwell only on the most important criteria. So, valuable and useful information in the first place should be:
- reliable;
- objective;
- complete;
- accurate;
- actual;
- useful.
