In the history of the development of human society, many times there have been significant changes in the field of information, which can be called revolutions.

The first information revolution is associated with the advent of writing. Writing gave people the opportunity to accumulate and disseminate knowledge. The second information revolution (mid-16th century) was associated with printing. There was an opportunity to make information mass-accessible, and not just save it. Literacy has become a phenomenon that has engulfed the broad masses of the people. There was an acceleration in the growth of science and technology, leading to the industrial revolution. Books crossed national borders, which led to the beginning of the creation of a universal civilization. The third information revolution (the end of the 19th century) was caused by great progress in the means of communication. The telegraph, telephone, radio made it possible to quickly transmit information over long distances. The fourth information revolution (70s of the XX century) is associated with the advent of microprocessors and personal computers. Computer telecommunications soon arose, greatly changing the systems for storing and retrieving information. The fourth information revolution has made significant changes in the development of society, a new term "information society" has appeared.

The information society is a society in which the majority of workers are engaged in the production, storage, processing and sale of information, especially its highest form - knowledge. Information becomes the subject of general consumption. The information society provides any subject with access to any source of information. It's guaranteed technical capabilities by law. There are new criteria for assessing the level of development of society - the number of computers, the number of Internet connections, the number of mobile and landlines etc.

Distinctive features:

• increasing the role of information, knowledge and information technologies in the life of society;
• an increase in the number of people employed information technology, communications and the production of information products and services, the growth of their share in the gross domestic product;
• the growing informatization of society with the use of telephony, radio, television, the Internet, as well as traditional and electronic media;
• creation of a global information space that provides: (a) effective information interaction of people, (b) their access to world information resources and (c) meeting their needs for information products and services;
• development of e-democracy, information economy, e-government, e-government, digital markets, electronic social and business networks;

The term "information society" owes its name to the professor of the Tokyo Institute of Technology Y. Hayashi, whose term was used in the works of F. Machlup (1962) and T. Umesao (1963) that appeared almost simultaneously - in Japan and the USA.

In the 1980s and 1990s, philosophers and sociologists developed the theory of the information society. In this work, the efforts of such well-known philosophers as Yoshita Masuda, Zbigniew Brzezinski, J. Nasbitt, M. Porat, T. Stoner, R. Karz, and others were combined.

The telecommunications revolution begins in the mid-70s and merges with the computer one. The computer revolution begins much earlier and proceeds in several stages.

The first stage takes 1930-1970, which is called the "zero cycle". It begins with the creation of the first computers in which electronic tubes replaced mechanical parts.

The second stage of the computer revolution begins with the creation of the first personal computers using integrated circuits and their mass production.

The telecommunications revolution is associated with the advent of fiber optic technologies and satellite technologies.

Merger of telecommunications and computer technology brought many new products and services to the market. The information and telecommunications industry has now become a key sector of the economy of developed countries. They consider it necessary to import consumer goods, but export information industry products, and earn national wealth from their sale.

Information technology is much more expensive than consumer goods, which provides developed countries with a high standard of living. And leadership in information technology gives them the opportunity to continue to claim political leadership in the world.

Thanks to the merging of the computer and telecommunications revolutions, information networks huge scale, including global. Through these networks, it is possible to transmit, find and process the necessary information much faster.

Information resources are understood as information recorded on a tangible medium and stored in information systems(libraries, archives, collections, data banks, etc.). An information resource may belong to one person or group of persons, organization, city, region, country, world. An information resource is a product of the activity of the most qualified part of society.

There is one difference between information and other resources: every resource disappears after use, but information does not, it can be used many times, it can be copied without restrictions. Moreover, the information resource tends to increase, since the use of information is rarely completely passive, more often additional information appears.

Information resources are divided into state and non-state. According to access categories, information is divided into open and restricted access. Information with limited access is divided, in turn, into information constituting a state secret and simply confidential.

Stages of development of technical means and information resources. From the history of mankind, we know that some scientific inventions have greatly influenced its course, the development of civilization. These include the invention of the wheel, the steam engine, the discovery of electricity, the mastery of atomic energy, etc. The processes of a sharp change in the nature of production, which lead to important scientific discoveries, are usually called the scientific and technological revolution (STR).

Appearance computer technology in the second half of the 20th century it became the most important factor in the scientific and technological revolution.

First stage begins with the creation of the first electronic computer ENIAC (computer) in 1945. For about 30 years, computers were used by a small number of people, mainly in the scientific and industrial fields.

Second phase begins in the mid-70s and is associated with the emergence and widespread distribution of personal computers (PCs). PCs have become widely used not only in science and production, but also in the system of general education, the service sector, and everyday life. PC entered the house as one of the species household appliances along with TVs, tape recorders.

Third stage associated with the emergence of the global computer network Internet. With the advent of the Internet, a PC that fits on a desk has become a window into a vast world of information. Such concepts as "world information space", "cyberspace" appeared. It is the emergence of the Internet that makes it possible to say that in the history of civilization the stage of "information-oriented society" is coming.

With the spread of the PC, the concept of computer literacy arises. Computer literacy is a necessary level of knowledge and skills of a person, allowing him to use a computer for public and personal purposes.

At the first stage computer literacy was reduced to the ability to create programs. Programming was studied mainly in higher educational institutions; scientists, engineers, professional programmers owned it.

At the second stage under the general level of computer literacy began to understand the ability to work on a PC with application programs, to perform a minimum of actions in the environment operating system. Computer literacy at this level is becoming a mass phenomenon due to schooling, numerous courses, and self-study.

At the third, modern stage, an important element of computer literacy is the ability to use the Internet and its resources.

One of the stages of the transition to the information society is the computerization of society, where all attention is given to the development and universal introduction of computers that ensure the prompt receipt of the results of information processing and its accumulation.

The main instrument of computerization is the computer (or computer). Mankind has come a long way before reaching state of the art computer facilities.

The main stages in the development of computer technology are:

I. Manual period of automation of calculations began at the dawn of human civilization. It was based on the use of fingers and toes. Counting by grouping and rearranging objects was the forerunner of counting on the abacus, the most advanced counting instrument of antiquity. The analogue of the abacus in Russia is the abacus that has survived to this day. Using an abacus involves performing calculations by digits, i.e. the presence of some positional number system.

At the beginning of the 17th century, the Scottish mathematician J. Napier introduced logarithms, which had a revolutionary impact on counting. The slide rule invented by him has served engineers for more than 360 years. It is undoubtedly the crowning achievement of the computing tools of the manual period of automation.

II. The development of mechanics in the 17th century became a prerequisite for the creation of computing devices and instruments that use the mechanical method of computing. Here are the most significant results achieved along the way. 1623 - German scientist W. Schickard describes and implements in single copy a mechanical calculating machine designed to perform four arithmetic operations on six-digit numbers. 1642 - B. Pascal built an eight-digit operating model of a counting adding machine. 1673 - German mathematician Leibniz creates the first adding machine that allows you to perform all four arithmetic operations. Adding machines were used for practical calculations until the sixties of the XX century.

English mathematician Charles Babbage (Charles Babbage, 1792-1871) put forward the idea of ​​creating a program-controlled calculating machine with an arithmetic unit, a control device, input and printing. The second project of Babbage is an analytical engine that uses the principle of program control and was intended to calculate any algorithm. The analytical engine consisted of the following four main parts: warehouse - memory; mill - arithmetic device; control device; input/output devices. Simultaneously with the English scientist, Lady Ada Lovelace worked. She developed the first programs for the machine, laid down many ideas and introduced a number of concepts and terms that have survived to this day.

III. The electromechanical stage of VT development was the shortest and covers about 60 years- from the first tabulator by G. Hollerith to the first computer "ENIAC". 1887 - the creation by G. Hollerith in the USA of the first counting and analytical complex, consisting of a manual puncher, a sorting machine and a tabulator. One of its most famous applications is the processing of census results population in several countries, including Russia. Later, Hollerith's company became one of the four firms that laid the foundation for the well-known IBM Corporation. Beginning - 30s of the XX century - the development of computational and analytical systems, on the basis of which computer centers were created. 1930 - V. Bush develops a differential analyzer, later used for military purposes 1937 - J. Atanasov, K. Berry create electronic machine ABC. 1944 - G. Aiken develops and creates a controlled computer MARK-1. In the future, several more models were implemented. 1957 - the last major project of relay computing technology - RVM-I was created in the USSR, which was operated until 1965.

IV. The electronic stage, the beginning of which is associated with the creation in the USA at the end of 1945 of the electronic computer ENIAC. In the history of the development of computers, it is customary to distinguish several generations, each of which has its own distinctive features and unique characteristics. The main difference between machines different generations consists in the element base, logical architecture and software, in addition, they differ in speed, random access memory, methods of input and output of information, etc. This information is summarized in the table below.

With the development of society, participation in information processes began to require not only individual, but also collective knowledge and experience that contribute to the correct processing of information and the adoption of necessary decisions. To do this, a person needed various devices.

Information revolutions are the stages in the emergence of means and methods of information processing that caused fundamental changes in society, are defined as. At the same time, society moves to a higher level of development and acquires a new quality. Information revolutions define watersheds in world history, after which new stages in the development of civilization begin, fundamentally new technologies appear and develop.

The first information revolution It is associated with the invention of writing, which led to a gigantic qualitative leap in the development of civilization. It became possible to accumulate knowledge in written form to pass it on to the next generations. From the standpoint of computer science, this can be assessed as the emergence of a qualitatively new (compared to the oral form) means and methods of information accumulation.

Second Information Revolution (mid-16th century) Typography is one of the first information technologies. It began in the Renaissance and is associated with the invention of printing, which changed human society, culture and organization of activity in the most radical way. Printing is one of the first information technologies.

A person has not just received new means of accumulating, systematizing and replicating information. The mass distribution of printed materials made cultural values ​​publicly available, opened up the possibility of independent and purposeful development of the individual. From the point of view of computer science, the significance of this revolution is that it has put forward a more advanced way of storing information.

The third information revolution (the end of the 19th century) Associated with the invention of electricity, thanks to which the telegraph, telephone and radio appeared, allowing you to quickly transfer information in any volume. It became possible to provide a more efficient exchange of information between people. This stage is important for informatics primarily because it marked the emergence of information communication tools.

on microprocessors and integrated circuits computers began to be built computer networks, data transmission systems ( information and communication systems), etc. Thanks to this revolution, for the first time in the history of its development, mankind received a means to strengthen its own intellectual activity. This tool is a computer.

Today, the term "information society" has firmly taken its place in the lexicon of politicians, economists, teachers and scientists. In most cases, this concept is associated with the level of development of information technology and telecommunications. The information society differs from a society dominated by traditional industry and the service sector in that information, knowledge, information services, and all industries associated with their production (telecommunications, computer, television) are growing at a faster pace, are a source of new jobs, become dominant in economic development. Information becomes the subject of mass consumption. The information society provides any individual with access to any source of information. This is guaranteed by law and technical possibilities. There are new criteria for assessing the level of development of society - the number of computers, the number of Internet connections, the number mobile phones etc.

In the history of the development of civilization, there have been several information revolutions - transformations of social relations due to fundamental changes in the field of information processing. The consequence of such transformations was the acquisition of a new quality by human society.

The first revolution was associated with the invention of writing, which led to a gigantic qualitative and quantitative leap. It became possible to transfer knowledge from generation to generation.

The second (mid-16th century) was caused by the invention of printing, which radically changed industrial society, culture, and the organization of activities.

The third (the end of the 19th century) is due to the invention of electricity, thanks to which the telegraph, telephone, and radio appeared, which made it possible to quickly transmit and accumulate information in any volume.

The fourth (70s of the XX century) is associated with the invention of microprocessor technology and the emergence of personal computer. Computers, computer networks, data transmission systems (information communications) are created on microprocessors and integrated circuits. This period is characterized by three fundamental innovations: the transition from mechanical and electrical means of information conversion to electronic ones; miniaturization of all nodes, devices, devices, machines; creation of software-controlled devices and processes.

The latest information revolution brings to the fore a new industry - the information industry associated with the production of technical means, methods, technologies for the production of new knowledge. All types of information technologies, especially telecommunications, are becoming the most important components of the information industry. Modern information technology is based on advances in computer technology and communications.

The activities of individuals, groups, teams and organizations now increasingly begin to depend on their awareness and ability to effectively use the available information. Before taking any action, it is necessary to do a lot of work on collecting and processing information, its comprehension and analysis. Finding rational solutions in any area requires the processing of large amounts of information, which is sometimes impossible without the involvement of special technical means.

The increase in the volume of information became especially noticeable in the middle of the 20th century. An avalanche-like flow of information poured over a person, not giving him the opportunity to fully perceive this information. In the daily emerging new stream of information, it became increasingly difficult to navigate. Sometimes it has become more profitable to create a new material or intellectual product than to search for an analogue made earlier. Modern material production and other areas of activity are increasingly in need of information services, processing huge amount information. A universal technical means of processing any information is a computer, which plays the role of an amplifier of the intellectual capabilities of a person and society as a whole, and communication tools using computers serve to communicate and transmit information. The emergence and development of computers is a necessary component of the process of informatization of society.

Informatization of society is an organized socio-economic and scientific-technical process of creating optimal conditions for meeting information needs and exercising the rights of citizens, state authorities, local governments, organizations, public associations based on the formation and use of information resources. Informatization of society is one of the patterns of modern social progress. This term is more and more insistently replacing the term "computerization of society", which was widely used until recently. Despite the outward similarity of these concepts, they have a significant difference. With the computerization of society, the main attention is paid to the development and implementation of the technical base of computers that ensure the prompt receipt of the results of information processing and its accumulation. When informatizing society, the main attention is paid to a set of measures aimed at ensuring the full use of reliable, comprehensive and timely knowledge in all types of human activity. Thus, "informatization of society" is a broader concept than "computerization of society", and is aimed at the speedy mastery of information to meet their needs. In the concept of "informatization of society", the emphasis should be placed not so much on technical means how much on the essence and purpose of socio-technical progress. Computers are the basic technical component of the process of informatization of society.

PLAN:

• The main stages in the development of the information society.
• Stages of development of technical and information resources.

1. The main stages in the development of the information society.

Since about the 17th century, there have been significant changes in the way information is stored and transmitted.

In the development of human society, there are four stages, named information revolutions who made changes to its development.

Information revolutions - transformation of social relations due to fundamental changes in the field of information processing. The consequence of such transformations was the acquisition of a new quality by human society.

Information revolutions

The first revolution (VI millennium BC) is associated with the invention of writing.

This led to a gigantic qualitative and quantitative leap.

It became possible to transfer knowledge from generation to generation.

Information revolutions

The second revolution (mid-16th century) was connected with the invention of printing.

This radically changed the industrial society, culture, organization of activities.

It became possible not only to save information, but also to make it massively accessible.

Literacy is becoming universal. All this accelerated the growth of science and technology, helped the industrial revolution.

Information revolutions

The third revolution (late 19th century) was driven by the invention of electricity.

Thanks to this invention appeared: telegraph, telephone, radio, allowing you to quickly transmit and accumulate information in any volume.

The degree of dissemination of information has increased, the role of the media has increased, and it has become possible for people to quickly communicate with each other.

Information revolutions

The fourth revolution (70s of the XX century) is associated with the invention of microprocessor technology and the appearance of a personal computer.

Computers, computer networks, data transmission systems (information communications) are created on microprocessors and integrated circuits.

This period is characterized by three fundamental innovations:

• transition from mechanical and electrical means of information conversion to electronic ones;
• miniaturization of all nodes, devices, devices, machines;
• Creation of software-controlled devices and processes.

The main features of the information society.

Information society - a society in which the majority of workers are engaged in the production, storage, processing and sale of information, especially its highest form - knowledge.

Distinctive features of the information society:

• increasing the role of information, knowledge and information technologies in the life of society;
• an increase in the number of people employed in information technology, communications and the production of information products and services, an increase in their share in the gross domestic product;
• the growing informatization of society with the use of telephony, radio, television, the Internet, as well as traditional and electronic media;
• creation of a global information space that provides: effective information interaction of people, their access to world information resources and satisfaction of their needs for information products and services;
• development of e-democracy, information economy, e-government, e-government, digital markets, electronic social and economic networks.

2. Stages of development of technical and information resources.

The development of computing technology can be divided into the following periods:

• Manual (VI century BC - XVII century AD);
• Mechanical (from the middle of the 17th century);
• Electromechanical - from the 90s of the 19th century;
• Electronic (mid-XX century - present).

At the same time, it should be borne in mind that the well-proven means of all four stages of the development of CT are used by mankind at the present time to automate various kinds of calculations.

Manual stage of development of computer technology

The manual period of computing automation began at the dawn of human civilization and was based on the use of body parts, primarily fingers and toes.

Accounting results were recorded different ways: notching, counting sticks, knots, etc., grouping and rearranging objects.

Manual stage of development of computer technology

About 3000 years ago (5th century BC), the first counting device, the abacus, began to be used for counting, from which the development of computer technology began.

Abacus - the most advanced counting device of antiquity, preserved to this day in the form various types accounts.

(Japanese abacus)

(Chinese abacus)

The development of mechanics in the 17th century became a prerequisite for the creation of computing devices and instruments using mechanical principle computing.

First mechanical machine (Shikkard machine) to perform arithmetic operations on 6-bit numbers was described in 1623 by V. Shikkard. It consisted of independent devices: adding, multiplying and writing numbers.

Mechanical stage in the development of computing technology

In 1642, the outstanding French scientist Blaise Pascal built the "Pascalina" - a machine that mechanically performs arithmetic operations over 10-bit numbers. Pascal's mechanical "computer" could add and subtract.

The Pascalina consisted of a set of vertically mounted wheels with numbers from 0 to 9 printed on them. It was very easy to count on the Pascalina.

Mechanical stage in the development of computing technology

In 1673, the German mathematician and philosopher G.V. Leibniz designed the first adding machine, a calculating device that not only added and subtracted, but also multiplied and divided.

Arithmometers have become widespread and have been repeatedly modified.

Mechanical stage in the development of computing technology

In the 30s of the 19th century. The Englishman Charles Babage proposed an analytical engine using the principle of program control, which was the forerunner of modern computers.

In 1843, Ada Lovelace (the granddaughter of the poet Byron) wrote the world's first fairly complex program for calculating Bernoulli numbers for the Babage machine.

The project of the analytical engine was not implemented, but it was widely known and highly appreciated by a number of scientists, primarily mathematicians.

It was the least long and covers only about 60 years.

The prerequisites for the creation of projects at this stage were both the need for mass calculations (economics, statistics, management, planning, etc.) and the development of applied electrical engineering (electric drive and electromechanical relays).

The first calculating and analytical complex was created in the USA in 1887 by G. Hollerith (Hollerith's tabulator). It was used for the population census in Russia (1897), the USA (1890) and Canada (1897), for processing reports on the US railroads, in large trading firms.

Electromechanical stage in the development of computer technology

In 1941, Konrad Zuse built a machine similar to the tabulator, with program management and storage device.

In 1944, Aiken built the MARK-1 analytical engine based on an electromechanical relay at an IBM company.

Electromechanical stage in the development of computer technology

In the USSR in 1957 a relay computer (RVM-1) was built.

This was the last, major relay VT project. During this period, machine counting stations were created, which were mechanized counting enterprises.

Due to the physical and technical nature, the relay VT did not allow a significant increase in the speed of calculations; this required a transition to high-speed electronic inertial-free elements.

All electronic computing equipment is usually divided into generations.

The change of generations depends on the element base of the computer, i.e. technical basis.

Electronic stage of development of computer technology

I generation (1945-1959)

• Systemic software was missing.
• They were narrowly specialized in solving mathematical problems.

• The elemental base of the machines of the first generation is electron-vacuum lamps.

• Computers required a large area of ​​the premises. To maintain their performance, a staff of experienced engineers was required, able to quickly find a malfunction and fix it.

Included:

• one memory device;
• one arithmetic unit;
• several primitive input-output devices.

Computer examples: EDSAC, ENIAС, BESM.

Electronic stage of development of computer technology

II generation (1950-1963)

• Semiconductor devices - transistors, diodes - became the element base.

• Computers of the second generation were already used not only for computational mathematics, but also for solving data processing problems.

• The performance of these machines reached from 500 thousand to 2 million operations per second, the amount of RAM reached from 8 MB to 192 MB.

• The basis of machines of the III generation was integrated circuits.

• The size of computers has drastically decreased. Significantly increased speed.

• The composition of the computer included convenient output devices - displays.

Machines of this generation: IBM-360, MINSK-32, etc.

Electronic stage of development of computer technology

IV generation (1977 - present day)

• This is the first type of computer that appeared in retail.

• The element base of these machines became LSI (large integrated circuits).

• A significant difference between microcomputers and their predecessors is their small size and comparative cheapness.

• The PC hardware set uses a color graphic display, mouse and joystick manipulators, a comfortable keyboard, user-friendly compact disks (magnetic and optical).

Examples: IBM PC, ELBRUS, etc.

Electronic stage of development of computer technology

V generation (computer of the future)

• Fifth generation machines are realized artificial intelligence. They will be able to input from the voice, voice communication, machine "vision", machine "touch".

• Their main quality should be a high intellectual level.

• To increase memory and performance, the achievements of optoelectronics and bioprocessors will be used.

Much has already been practically done in this direction.
