concept of information in the modern scientific world is ambiguous.Despite the fact that it appeared quite a long time, until now, scientists can not give a strict definition of that term and argue that it should be considered as indeterminate concepts primary.In textbooks on computer science can find such definitions:
information - information or knowledge of anything;knowledge that can be collected, stored, transferred, processed and used.The information in the computer - the basic concept of science as computer science is called the science of information, its structure and properties, methods, processing and transmission.Informatics studies the information through the main tool - the computer.
The term translated from Latin means "information", "presentation".Today, science is looking for common properties and laws that are inherent in the information, but the information is in computer science - intuitive concept that has different meanings in different spheres of human activity.
Despite the presence of a large number of definitions, select the most common and understandable.Statistics - a reflection of the world through signals and signs.The value of the information message is new knowledge contained in it.
types of information in computer science.Depending on the mode of perception, it can be perceived by means of the eye, hearing, smell, taste and touch.In addition, the form of presentation isolated text, numeric, graphic and sound.The labeling is the same, and video.
information in the computer has a number of properties.These include the completeness, reliability, timeliness, accessibility, security, relevancy (the ability to meet the needs), ergonomics.
information as a particular kind of resource has properties characteristic of him.These include: memorability, reproducibility, transferability, convertible and abrasion.
This data carrier can be any object of the material world, the waves (acoustic, electromagnetic, etc.), the material in any condition.There are also machine-readable media (eg, tape).Transmits information to computer by means of signals.
signal - a physical process, which has informative value and can be discrete or continuous.The first takes only a finite number of values for a certain number of times, and continuous - one that is constantly changing both in time and amplitude.Signals that are symbolic or textual information - discrete.Examples of analog signals can lead telephone or television.
Today informatics is developing very rapidly, and today in the science of information identifies a number of new areas, such as programming, cybernetics, artificial intelligence, computer technology, information systems and theoretical information.The concept of information in computer science - is relatively new in the lexicon of rights, and despite the widespread use of the word in question, its content is still unclear and blurred.Computers connected to the information and processing it on computers.On an intuitive level, everything is clear, however, if you look closely, the issue becomes much more complicated than it might seem at first glance.
Since computers today are widespread, and mankind is experiencing an information boom, the basics of computer science should be understood by every modern individual who wants at least a little to keep pace with the times.These factors have influenced the fact that the teaching of computer science was introduced in the school curriculum, and every young person has the opportunity to learn this new but very interesting and necessary science.
