Basic Concepts. Information activities. Computer science. Information Technology. Computer, its capabilities and areas of application.
Computer science defines the scope of human activity associated with the processes of storing, converting and transmitting information using a computer. This activity is called informational.The core of computer science is information Technology.
Information Technology is a set of methods and devices used by people to process information. Computer, computer networks and them software are the foundation of modern information technologies.
Initially, the computer was created to automate calculations. Currently, computers are used to process not only numerical but also other types of information.
Today, the computer is both an assistant in business, and a source of fresh news from the World Wide Web - the Internet, and a means mobile communications, allowing, for example, using Email quickly transmit and receive information.
Computers in production are used at all stages: from the construction of individual parts of a product, its design to assembly and sale. The computer-aided design (CAD) system allows you to create drawings, immediately obtaining a general view of the object, and control machines for the production of parts. A flexible production system (FPS) allows you to quickly respond to changes in the market situation, quickly expand or curtail the production of a product, or replace it with another. The ease of transferring the conveyor to the production of new products makes it possible to produce many different product models. Computers make it possible to quickly process information from various sensors, including from automated security, from temperature sensors to regulate energy consumption for heating, from ATMs that record the spending of money by clients, from a complex tomography system that allows you to “see” the internal structure of human organs and make a correct diagnosis.
The development of methods and techniques for presenting information, technology for solving problems using computers, has become an important aspect of the activities of people in many professions.
The computer is located on the desktop of a specialist in any profession. It allows you to contact by special computer mail with anywhere in the world, connect to the collections of large libraries without leaving home, use powerful Information Systems- encyclopedias, study new sciences and acquire various skills with the help of training programs and simulators. He helps the fashion designer to develop patterns, the publisher to arrange text and illustrations, the artist to create new paintings, and the composer to create music. An expensive experiment can be completely calculated and simulated on a computer.
Thanks to all of the above, computer science and computer science have become firmly established in the life of modern people and are widely used in production, design work, business and many other industries. The process of informatization of society has begun.
Informatization of society is a process by which conditions are created that satisfy the needs of any person to receive necessary information
Conclusion. In the modern world, the role of computer science, means of processing, transmitting, and storing information has increased immeasurably. Information science and computer technology now largely determine the scientific and technical potential of the country, the level of development of its national economy, the way of life and human activity.

Information activities– activities that ensure the collection, processing, storage, retrieval and dissemination of information, as well as the formation of an information resource and the organization of access to it.
Information has always played an extremely important role in human life. Whoever has the most information on any issue is always in a better position than others. It is a well-known saying that whoever owns the information owns the world.
Since ancient times, collecting and systematizing information about the world around us has helped people survive in difficult conditions - experience and skills in making hunting and labor tools, creating clothing and medicines have been passed on from generation to generation. The information was constantly updated and supplemented - each studied phenomenon made it possible to move on to something new, more complex.
Over time, large volumes of data about the surrounding world contributed to the development of scientific and technological progress and, as a result, the entire society as a whole - people were able to learn to control various types of matter and energy.
Over time, the role of information in human life has become more and more significant. Now, in the first half of the 21st century, the role of information in a person’s life is decisive - the more skills and knowledge he has, the higher he is valued as a specialist and employee, the more respect he has in society.
In recent decades, there has been persistent talk about the transition from an “industrial society” to an “information society.”
There is a change in production methods, people's worldviews, and their way of life. At the same time, changes are taking place in the nature of work, which is an indicator of the degree of freedom of working individuals, an indicator of their attitude towards work. This is expressed, first of all, in the “learning” of labor - in the increasing scale of application of scientific knowledge in the production process, which leads to an increase in creativity in the labor process. Labor becomes more creative, the share of mental labor increases, the importance of its individual characteristics increases, and accordingly the share of physical labor, which exhausts a person’s muscular strength, decreases. New technology requires not standard performers, not robots, but individuals, creative personalities.
Information has become one of the most important strategic and management resources, along with resources - human, financial, and material. The use of microprocessor technology, electronic computers and personal computers has led to a radical transformation of relationships and technological foundations of activity in various spheres of public life: production and consumption, financial activity and trade, the social structure of society and political life, the service sector and spiritual culture.
Information activity plays a huge role in the modern world and is very closely related to the concept of and. With the advent of information technologies, or rather their improvement, since books or even cuneiform writing together with speech are ID, and the development of the Internet as an effective communication channel, much has changed in our lives, thanks to more simple exchange knowledge between people.
Definition and characteristics
Let's now look at what is meant by information activity (hereinafter referred to as ID). ID is the collection, storage, distribution and also creation of a resource and provision of unlimited access to it. A simple example is this site. Filling a website with information and posting it on the Internet is ID. Let's look (Fig. 1) at each point and briefly describe each of them:
- First collection, implies a set of measures for extraction, selection, and in some cases even analysis .
- Second , — organizing a reliable method of conservation for future access.
- And last , spreading— this is the possibility of implementing publicly disclosed or documented information.
Rice. 1, Collection, storage and dissemination of information in modern society
Purpose of information activities
Information activities have the following target, satisfy the needs of individuals or legal entities for the information they need.
Thus we can form a definition:
The purpose of information activities is to satisfy the information needs of groups of people
The above activities have several areas in the following areas:
- Education
- Economy
- Science and technology
- Policy
- Social issues
Each of these areas makes its contribution to the development of modern society.
With the advent of a more advanced type of ID (more technological) to replace textbooks and voice in education, the workload of the teacher and teacher has decreased. For example, a schoolchild or student can, with the help personal computer and the Internet to obtain any necessary knowledge according to the curriculum.
Examples of IDs in different industries
- In economics, information activities make it possible to ensure demand for goods through advertising.
- In science, science articles accessible to almost any interested person and, as a result, the popularity of science grows and the number of interested people who can become scientists in the future increases, which in the future allows scientific progress to move forward.
- In politics, a type of media outlet is the media that allows you to cover current issues in the state, allows you to form, albeit one-sided, but still a connection with the masses.
Information activities on social issues. character help to draw attention to social groups who need help. Allows you to attract volunteers or funds to improve the conditions of such people. which allows us to change society for the better.

INTRODUCTION
Information has always played an extremely important role in human life. It is a well-known saying that whoever owns the information owns the world.
Since ancient times, collecting and systematizing information about the world around us has helped people survive in difficult conditions - experience and skills in making hunting and labor tools, creating clothing and medicines have been passed on from generation to generation. The information was constantly updated and supplemented - each studied phenomenon made it possible to move on to something new, more complex. Over time, large volumes of data about the world around us contributed to the development of scientific and technological progress and, as a result, of society as a whole - people learned to manage various types of matter and energy.
Over time, the role of information in human life has become more and more significant. It was necessary to study and understand not only the laws of nature, but also the concepts and values of human society - literature, art, architecture, etc.
In modern society, the role of information in a person’s life is decisive - the more information he owns, the higher his value in society.
The purpose of this work is to reveal the concept of information and outline the place of information in modern society.
1. Information and its role in modern society
1.1 Concept of information and its types
Understanding the world around us, a person constantly deals with information.
In modern society it is impossible to imagine the existence of a person separately from the concept of “information”. The term information is used in many sciences and in many areas of human activity. It comes from the Latin word “informatio”, which means “information, explanation, presentation.”
Despite the familiarity of this term, there is no strict and generally accepted definition. In the literature you can find quite a lot of definitions of this term, reflecting different approaches to the interpretation of this concept.
So in Federal Law Russian Federation“On information, informatization and information protection” the following definition is given: “information is information about persons, objects, facts, events, phenomena and processes, regardless of the form of their presentation.” The Federal Law “On Information, Information Technologies and Information Protection” defines the concept of information as follows: “information (messages, data) regardless of the form of their presentation.”
In computer science, the following definition of the term information is most often used - this is conscious information about the world around us, which is the object of storage, transformation, transmission and use. Information is knowledge expressed in signals, messages, news, notifications, etc.
The main types of information according to its form of representation, methods of encoding and storing it, which is of greatest importance for computer science, are:
Graphic or pictorial - the first type for which a method of storing information about the surrounding world was implemented in the form of rock paintings, and later in the form of paintings, photographs, diagrams, drawings on paper, canvas, marble and other materials depicting pictures of the real world;
Sound - the world around us is full of sounds and the problem of storing and replicating them was solved with the invention of sound recording devices in 1877, its type is musical information - for this type a coding method was invented using special characters, which makes it possible to store it in a similar way to graphic information ;
Text - a way of encoding human speech with special symbols - letters, and different nations have different languages and use different sets of letters to represent speech; This method became especially important after the invention of paper and printing;
Numerical - a quantitative measure of objects and their properties in the surrounding world; acquired especially great importance with the development of trade, economics and monetary exchange; similarly text information to display it, a coding method is used with special symbols - numbers, and the coding (number) systems can be different;
Video information is a way of preserving moving pictures of the surrounding world, which appeared with the invention of cinema.
There are also types of information for which methods for encoding and storing them have not yet been invented - this is tactile information transmitted by sensations, organoleptic information transmitted by smells and tastes, and other types for which modern science has not even found universally accepted definitions (for example, extrasensory information).
To transmit information over long distances, coded light signals were initially used, with the invention of electricity - transmission of a signal encoded in a certain way through wires, and later using radio waves.
Information storage when using computers is carried out on magnetic disks or tapes, on laser disks (CD and DVD), special non-volatile memory devices (flash memory, etc.). These methods are constantly being improved, new devices and storage media are being invented. Information processing (reproduction, transformation, transmission, recording on external media) is performed by the computer processor. Using a computer, it is possible to create and store new information of any kind, for which they serve special programs, used on computers, and information input devices.
A special type of information can currently be considered information presented in global network Internet. It uses special techniques for storing, processing, retrieving and transmitting large volumes of distributed information and special ways of working with various types of information.
Software from leading developers (for example, Microsoft Corporation) is constantly being improved, providing collective work with corporate information of all types.
1.2 Properties of information
Like any object, information has properties. Characteristic distinctive feature information from other objects of nature and society is dualism: the properties of information are influenced both by the properties of the source data that make up its content and by the properties of the methods that record this information.
The most important properties of information are its general qualitative properties: objectivity, reliability, completeness, accuracy, relevance, usefulness, value, timeliness, understandability, accessibility, brevity, etc.
Objectivity of information. Objective - existing outside and independently of human consciousness. Information is a reflection of the external objective world. Information is objective if it does not depend on the methods of its recording, anyone’s opinion, or judgment. For example, the message “It’s warm outside” carries subjective information, while the message “It’s 22 degrees Celsius outside” carries objective information, but with an accuracy that depends on the error of the measuring instrument.
Objective information can be obtained using measuring instruments. Reflected in the consciousness of a particular person, information ceases to be objective, since it is transformed (to a greater or lesser extent) depending on the opinion, judgment, experience, and knowledge of a particular subject.
Reliability of information. Information is reliable if it reflects the true state of affairs. Objective information is always reliable, but reliable information can be both objective and subjective. Reliable information helps us make the right decision.
Information may be inaccurate for the following reasons:
Intentional distortion (misinformation) or unintentional distortion of a subjective property;
Distortion due to interference and insufficiently accurate measuring instruments.
Completeness of information. Information can be called complete if it is sufficient for understanding and making decisions. Not full information may lead to an erroneous conclusion or decision.
The accuracy of information is determined by the degree of its proximity to the real state of an object, process, phenomenon (the error of the measuring instrument).
Relevance of information - importance for the present time, topicality, urgency. Sometimes only timely information received can be useful.
Usefulness (value) of information. Utility can be assessed in relation to the needs of its specific consumers and is assessed by those tasks that can be solved with its help.
The most valuable information is objective, reliable, complete, and up-to-date. It should be taken into account that biased, unreliable information (for example, fiction) is of great significance for a person.
Social (public) information also has additional properties:
It has a semantic (notional) character, i.e. conceptual, since it is in concepts that the most essential features of objects, processes and phenomena of the surrounding world are generalized.
It has a linguistic nature (except for some types of aesthetic information, such as fine arts). The same content can be expressed in different natural (spoken) languages, written in the form of mathematical formulas, etc.
Over time, the amount of information grows, information accumulates, it is systematized, evaluated and generalized. This property was called growth and accumulation of information. (Cumulation - from Lat; cumulatio - increase, accumulation).
Information aging is the decrease in its value over time. Information ages when new information appears that clarifies, supplements, or rejects, in whole or in part, earlier information. Scientific and technical information ages faster, aesthetic information (works of art) - slower.
Logicality, compactness, convenient form of presentation facilitates understanding and assimilation of information.
1.3 Concept of amount of information
The property of completeness of information tacitly assumes that it is possible to measure the amount of information. The amount of information is a numerical characteristic of information that reflects the degree of uncertainty that disappears after receiving information. The concepts of “information”, “uncertainty”, “choice” are closely related. For example, a person suggested in the morning that there may or may not be precipitation during the day, and if there is, it will be in the form of snow or rain, i.e. it’s unclear - “either it will be or not, it’s either rain or snow.” Then, looking out the window, he saw a cloudy sky and high probability assumed that there would be precipitation, i.e., having received the information, he reduced the number of choices. Next, looking at the outside thermometer, he saw that the temperature was negative, which means precipitation should be expected in the form of snow. Thus, having received the latest temperature data, a person received complete information about the upcoming weather and eliminated all but one choice.
The information received reduces the number possible options choice (i.e. uncertainty), and complete information leaves no options at all.
One bit is taken as a unit of information (English bit -- binary digit -- binary digit). This is the amount of information at which uncertainty, i.e. the number of choices is reduced by half or, in other words, this is the answer to a question that requires a monosyllabic solution - yes or no.
A bit is too small a unit of information. In practice, larger units are more often used, for example, a byte, which is a sequence of eight bits. It is eight bits, or one byte, that is used to encode the characters of the alphabet, the keys of a computer keyboard. One byte is also the minimum unit of addressable memory in a computer, i.e. You can access memory by a byte, not a bit.
Even larger derived units of information are widely used:
1 Kilobyte (KB) = 1024 bytes = 210 bytes,
1 Megabyte (MB) = 1024 KB = 220 bytes,
1 Gigabyte (GB) = 1024 MB = 230 bytes,
1 Terabyte (TB) = 1024 GB = 240 bytes.
1.4 Information processes
Obtaining information is closely related to information processes. For the purposeful use of information, it must be collected, transformed, transmitted, accumulated and systematized. All these processes associated with certain operations on information are called information processes. There are the following types information processes.
Data collection is the activity of a subject to accumulate data in order to ensure sufficient completeness. When combined with adequate methods, data gives rise to information that can help in decision making. For example, being interested in the price of a product, its consumer properties, we collect information in order to make a decision: to buy or not to buy it.
Data transmission is the process of exchanging data. It is assumed that there is a source of information, a communication channel, a receiver of information, and agreements have been adopted between them on the procedure for exchanging data; these agreements are called exchange protocols. For example, in a normal conversation, there is an unspoken agreement between two people not to interrupt each other during a conversation.
Data storage is the maintenance of data in a form that is constantly ready for delivery to the consumer. The same data may be required more than once, so a method of storing it (usually on physical media) and methods of accessing it at the request of the consumer are being developed.
Data processing is the process of transforming information from its original form to a specific result. Collection, accumulation, and storage of information are often not the final goal of the information process. Most often, primary data is used to solve a problem, then it is transformed step by step in accordance with the algorithm for solving the problem until it is obtained.
output data that, after analysis by the user, provides the necessary information.
1.5 The role of information in modern society
Humanity, from the day it emerged from the animal world, has devoted a significant part of its time and attention to information processes.
Nowadays, millions of people have become users of information. Cheap computers appeared that were available to millions of users. Computers have become multimedia, i.e. they process different kinds information: sound, graphic, video, etc. This, in turn, gave impetus to the widespread use of computers in various fields of science, technology, production, and everyday life.
Communication means have become widespread, and computers are connected into computer networks to participate jointly in the information process. The worldwide computer network Internet has appeared, the services of which are used by a significant part of the world's population, quickly receiving and exchanging data, i.e. a single global information space is being formed.
Currently, the circle of people involved in information processing has grown to unprecedented proportions, and the speed of exchange has become simply fantastic; computers are used in almost all areas of people's lives. Before our eyes, an information society is emerging, where the emphasis of attention and importance is shifting from traditional types of resources (material, financial, energy, etc.) to information resource, which, although it has always existed, was not considered either as an economic or as another category. Information resources are individual documents and arrays of documents in libraries, archives, funds, data banks, information systems and other repositories. In other words, information resources are knowledge prepared by people for social use in society and recorded on material media. The information resources of a country, region, or organization are increasingly considered as strategic resources, similar in importance to reserves of raw materials, energy, minerals and other resources.
The development of global information resources has made it possible to transform the activity of providing information services into a global human activity, to form a global and domestic market for information services, to increase the validity and efficiency of decisions made in firms, banks, exchanges, industry, and trade through the timely use of the necessary information.
In the modern world, the role of information, the means of its processing, transmission and accumulation has increased immeasurably. Information science and computer technology now largely determine the scientific and technical potential of the country, the level of development of its national economy, the way of life and human activity.
Receiving and transforming information is a necessary condition for the functioning of society.
Information has become one of the most important strategic and management resources, along with resources - human, financial, and material. Its production and consumption constitute the necessary basis for the effective functioning and development of various spheres of social life, and, above all, the economy. This means that not only sources of information in any part of our planet become available to every person, but also the new information generated by him becomes the property of all humanity. In modern conditions, the right to information and access to it are of vital value for all members of society. The growing role of information in society has been the subject of scientific understanding. Theories have been put forward to explain its place and significance. The most popular theories are the post-industrial and information society.
The world is entering a new era - the information era, the age of electronic economic activity, online communities and borderless organizations. The advent of new times will radically change the economic and social aspects of society. Such changes most directly affect the place of man in the information world. A person changes in accordance with the vector of information and technical characteristics of society. However, this is not at all a passive acceptance of new conditions of production and consumption. A person acts as a subject of information reality, far beyond information specifications. The informatization of everyday life and the emergence of a new information field of human existence does not pass without leaving a mark on the human life world. In the electronic space, behavioral standards and value orientations of individuals change.
New conditions for world humanity are manifested in a special form in Russia. Modern Russia is not yet an information society. First of all, because some of the information is not available to a wide range of users or has been replaced by misinformation. However, the informatization of certain segments of social life, certain spheres of politics and economics will sooner or later create conditions for the emergence of a genuine social fabric of a new type, from which an information society can grow. Post-industrial trends can be quite organically combined with the characteristics of Russian civilization.
The information society is often called a mass society and a consumer society. This is due to such informatization processes as the development of the sphere of mass communications. Global and local computer networks, tools cellular communications, television and radio broadcasting system, being components information structure society, and at the same time ensure communication between people. Mass communication is one of the important phenomena of modern society, which significantly affects the development of all technologies, information technologies in particular, both within each country and between countries. Often, informatization processes are given a negative connotation, which is inherent in a consumer society. Many representatives of social and scientific thought see in informatization processes that are destructive for the spiritual sphere of society and associate information civilization with the antipode of culture and spirituality.
In the field of theoretical understanding of ongoing processes, there is also still no consensus regarding the ways of development of the information society, the priority of one or another of its directions, the clarity and precision of formulations and concepts expressing what is happening in information sphere. Therefore, theoretical research into both conceptual and practical (real) prerequisites for understanding current information processes remains relevant.
information society resource world
CONCLUSION
In this work, the concept of information was defined, its types were considered, and the main properties of information were given. The concept of the amount of information is given. The main types of information processes are considered. The role and place of information in modern society is described. The objectives of the work have been achieved.
To summarize, I would like to note that an information society is emerging before our eyes, where the emphasis of attention and significance is shifting from traditional types of resources (material, financial, energy, etc.) to an information resource, which, although it has always existed, was not considered as an economic , nor any other category. Information is beginning to play a dominant role not only in its traditional areas, but also in completely new ones. Society is moving into a new information era.

Introduction
The role of information activity in modern society
Basic Concepts. Information activities. Computer science. Information Technology. Computer, its capabilities and areas of application.
Computer science defines the scope of human activity associated with the processes of storing, converting and transmitting information using a computer. This activity is called informational. The core of computer science is information technology.
Information Technology is a set of methods and devices used by people to process information. The computer, computer networks and their software are the foundation of modern information technologies.
Initially, the computer was created to automate calculations. Currently, computers are used to process not only numerical but also other types of information.
Today, the computer is both an assistant in business, and a source of the latest news from the World Wide Web - the Internet, and a means of mobile communication, which allows, for example, using e-mail to quickly transmit and receive information.
Computers in production are used at all stages: from the construction of individual parts of a product, its design to assembly and sale. The computer-aided design (CAD) system allows you to create drawings, immediately obtaining a general view of the object, and control machines for the production of parts. A flexible production system (FPS) allows you to quickly respond to changes in the market situation, quickly expand or curtail the production of a product, or replace it with another. The ease of transferring the conveyor to the production of new products makes it possible to produce many different product models. Computers allow you to quickly process information from various sensors, including from automated security, from temperature sensors to regulate energy costs for heating, from ATMs that record the spending of money by customers, from a complex tomography system that allows you to “see” the internal structure of human organs and correctly place diagnosis.
The development of methods and techniques for presenting information, technology for solving problems using computers, has become an important aspect of the activities of people in many professions.
The computer is located on the desktop of a specialist in any profession. It allows you to contact any part of the world via a special computer mail, connect to the collections of large libraries without leaving your home, use powerful information systems - encyclopedias, study new sciences and acquire various skills with the help of training programs and simulators. He helps the fashion designer to develop patterns, the publisher to arrange text and illustrations, the artist to create new paintings, and the composer to create music. An expensive experiment can be completely calculated and simulated on a computer.
Thanks to all of the above, computer science and computer science have become firmly established in the life of modern people and are widely used in production, design work, business and many other industries. The process of informatization of society has begun.
Informatization of society is a process by which conditions are created that satisfy the needs of any person to obtain the necessary information
Conclusion. In the modern world, the role of computer science, means of processing, transmitting, and storing information has increased immeasurably. Information science and computer technology now largely determine the scientific and technical potential of the country, the level of development of its national economy, the way of life and human activity.
