This article is devoted to the consideration of such issues as the subject and tasks of computer science. Before proceeding to their coverage, let us define the term, the meaning of which should be clearly marked.

The word «informatics» first appeared in Francein the 60s of the last century to designate an area that deals with automated processing of information and uses for this purpose electronic computers. The term was formed by the merger of the other two — «automation» and «information». It means automated processing of information or information automation. This term corresponds to the term «computer science» in English-speaking countries, that is, the science of computer technology.

We offer the reader to preliminarily consider such topics as the subject and tasks of computer science, acquaintance with the history of its emergence.

History of Information Science

We can find the sources of information even in the depthscenturies. The need to express and remember it led many centuries ago to the emergence of speech, counting, writing. Our ancestors tried to invent and further improve the ways of storing information, its processing and distribution. Various evidence of attempts by people of the distant past to preserve it have been found in our days. These are methods such as recordings on clay tablets and birch bark, rock carvings, and then hand-written books.

In the 16th century a printing press appeared. His invention contributed to a significant increase in the ability to store and process the necessary information. The information presented in printed form was the main way of exchange and storage, and continued to remain until the middle of the 20th century. Only with the advent of computers appeared fundamentally new, much more effective ways of storing, collecting, transmitting, processing, the object and tasks of computer science were formulated.

General definition of informatics

You can give a lot of its definitions. This is due to the multifaceted nature of its methods, forms, capabilities and functions. The following definition of the concept of «informatics» is one of the most common.

Informatics is an areahuman activity, which is associated with various processes of information transformation, carried out with the help of computers, as well as with their interaction with the appropriate application environment.

Cybernetics and Informatics

Often there is a confusion of two concepts: «cybernetics» and «informatics». Let’s determine what their similarities are and how they differ from each other.

Cybernetics is the science of some general principlesmanagement, operating in various systems: social, biological, technical, etc. The subject and tasks of computer science are somewhat different. She studies more widely the processes of creating and transforming information, almost without affecting the solution of tasks related to the management of certain objects, as cybernetics does. Its emergence became possible due to the development of computer technology, which is based on it and is inconceivable without it. The development of cybernetics takes place by itself and, although it uses rather actively the achievements of computer technology, does not depend on them at all, as it builds different models of object management.

Informatics in the broad and narrow sense of the word

In the broad sense of the word, computer science is a unityvarious branches of science, production and technology, which are associated with the processing of information. And what about the narrow sense? It can identify 3 interconnected parts of computer science.

1. Informatics as a branch of the national economy

The first of them is the branch of the national economy. In this sense, computer science consists of some homogeneous set of firms that carry out various forms of management, which are engaged in the production of software products, computer equipment and the development of information processing technology. The significance, specificity, goals and tasks of informatics in this sense are determined by the fact that it is to this extent that the growth of labor productivity in various branches of the national economy depends largely on it. A lot of jobs around the world today are equipped with automation tools.

2. Informatics as a fundamental science

As the fundamental science of computer sciencedevelops the methodology of information support for various processes of object management on the basis of computer information systems. One can single out the following leading scientific directions in Europe: medical and economic informatics, computer-integrated production, development of network structure, informatics of environment and social insurance, professional information systems.

Let’s describe the main goals and tasks of computer sciencefundamental. Its goal is to obtain generalized knowledge of various information systems, as well as to identify in their functioning and the construction of general patterns. Its tasks are as follows:

— explore various theories of information systems and technologies;

— Develop a methodology for how to create information support for certain computer systems.

3. Applied aspect

Describing the subject of computer science as an applied science, we note that it deals with:

— the creation of various information communication models that function in a variety of areas of human activity;

— study of regularities that exist in information processes (distribution, processing, accumulation);

— development of technologies and information systemsin specific areas, as well as the development of recommendations relating to their life cycle for different stages (design, production, operation, etc.).

The main tasks of computer science

Its main function is to develop tools and methods for converting information, as well as to use them in organizing various technological processes for its processing.

The following main tasks of computer science can be distinguished:

— research of information processes having any nature;

— solution of engineering and scientific problems of introduction, creation, ensuring the most effective use of computer technology and technology in various areas of public life;

— development of information technology, as well as the creation on the basis of research results of various information processes of the latest information processing technology.

Informatics as a Comprehensive Discipline

It should be said that it does not exist by itselfitself. Informatics is a complex discipline (scientific and technical), which is aimed at creating new information technologies and techniques. They serve to solve problems arising in other areas. In the information society, the complex of its industry is the leading one. In the world there is a tendency to increasing awareness. It depends to a large extent on the progress of this particular area of ​​knowledge, its unity as science, production and technology.

Areas of application of informatics

Informatics today is widely used invarious areas of our lives: in science, production, education and many other areas of activity. The need for costly and complex experiments inevitably arises in connection with the development of modern science. An example is the development of thermonuclear reactors. The role of computer science is to replace real experiments with machines. This saves significant resources, provides the opportunity to process the most modern methods of the results. In addition, these experiments take much less time than real ones. And in some areas of scientific knowledge (for example, in astrophysics) it is simply impossible to carry out a real experiment. Then computer science comes to the rescue. Basically, in these areas, all studies are carried out using model and computational experiments.

The further development of informatics, as well as of any other science, leads to new discoveries and achievements. There are new applications that were previously difficult to even guess.

Communication of informatics with other branches of knowledge

Informatics is a broad field of scientific knowledge that arose at the interface of applied and fundamental disciplines. As a complex scientific discipline, it is associated with the following branches of knowledge:

— with psychology and philosophy (through the theory of knowledge and the doctrine of information);

— with mathematics (through discrete mathematics, the theory of mathematical modeling and algorithms, mathematical logic);

— with linguistics it is connected through the doctrine of sign systems and formal languages;

— with cybernetics, as we have already noted, — through the theory of management and information;

— with radio engineering, electronics, chemistry and physics — through the material part of information systems and the computer.

In the field of view of the science of informatics fallComputational sciences that study the methods and principles of organizing various computing processes, global and local computer networks. On the other hand, it also includes cognitive sciences that are designed to study human efforts in the field of thinking in order to improve the intellectual qualities of computers.

Informatics as a branch of economy

As a branch of the economy, computer science representsa set of economic entities that are designed to serve users (information), the production of processing facilities, as well as the creation of software. There is a tendency to move from an industrial society, where everything is directed to the production and consumption of goods, to the information society.

Today, various informatics tools are widely used in the economy. They are used in practice:

— trade, production and banking management;

— auditing and accounting;

— Budgetary process in municipal and state institutions;

— e-business and e-commerce;

— management of the treasury, auctions and trade exchanges.

Economic informatics is a science thatis designed to form the theory of modeling the activities of various economic entities, municipal, state and regional entities. Its goals are determined by the goals of the economy. That is, they consist in providing economic entities, municipal and state services and organizations with information technologies. What is the subject of informatics economics? It consists in the search for patterns that exist in information modeling, as well as methods for providing knowledge about the economic activities of organizations (enterprises) to an economic and other entity, and the introduction of information technology management in practice.

Methods of modeling and studying economic processes

There are many methods of modeling andstudy of economic processes. They are both specific and general scientific. General scientific: synthesis, analysis, induction, deduction, abstraction, analogy, concretization. All of them reveal regularities existing in stable phenomena or processes. Specific methods are oriented towards information phenomena reflecting economic processes, such as:

— mathematical: deterministic, stochastic, simulation, optimization and network modeling, fuzzy mathematics, mathematical, system, factor, regression and other types of analysis;

— information-logical: graphs and diagrams, graphs, visual and standardized means of representing information flows and business processes.

What is a computer?

Basic concepts of computer science includedifferent computers, since they are the main technical means used to process it. They can be classified according to a number of features: by designation, the principle of operation, the size of the computing power, the methods of organizing the computing process itself, functional capabilities,

Classification of computers by designation

You can divide the computer by its destination into the following 3 groups.

1. General purpose (universal). They are designed to solve various engineering and technical problems: mathematical, economic, information and others, which differ in the large amount of data to be processed, as well as in the complexity of the algorithms. Characteristic features of computer data are their high performance, as well as the variety of data forms to be processed (symbolic, decimal, binary), the variety of operations (special, logical, arithmetic), significant memory capacity, as well as a developed information input-output system .

2. The second group is problem-oriented. Their purpose is to solve a narrower range of tasks, which are usually associated with technological objects, accumulation, registration and processing of small amounts of data.

3. Specialized serve to solve a very narrow range of tasks. This reduces the cost and complexity of such computers, while maintaining reliability and greater productivity.

Information technology

Describing the basic concepts of computer science, you can notsay a few words about information technology. This is a combination of specific software and hardware that serve to perform various operations related to the processing of information in any areas of our lives. Information technology is sometimes called applied computer science or computer technology. This concept arose with the formation of an information society, in which the basis of social dynamics are information, rather than traditional material resources. This is a science, knowledge, intellectual abilities, organizational factors, creativity, initiative, etc. This concept, unfortunately, is so all-encompassing and general that specialists have not yet come to a clear formulation of it. The most successful definition of it was given by Academician Glushkov, who interpreted information technology as a human-machine technology for transferring, processing, collecting information based on the use of various computers. It is developing rapidly and covering more and more types of social activities: management, production, education, science, medicine, financial and banking operations, everyday life, etc.

School Informatics Course

The main task of the school subject «Informatics»is to ensure the conscious and lasting mastery of the students knowledge related to the processes of transformation, receipt, use, storage of information. On this basis, the computer science teacher should also reveal its role in the formation of the scientific picture of the world that has developed in our days, the importance of computer technology and information technology in the development of modern society. The task is also to instill in students the skills of rational and conscious use of computers in educational and professional activities.

The following questions should be covered by the computer science teacher:

— information, various information processes, as well as the languages ​​of its presentation;

— information modeling;

— programming and algorithmization;

— The computer as a means of information processing;

— existing today the new information technology for its processing.

These lines are cross-cutting, that isstudying them occurs at all stages (from 2 to 11 class). Computer science is divided into three levels at school. These levels take into account the age of the students, as well as their preparation.

The first level — the initial (from 2 to 6 class),the second — the basic (from 7 to 9 class), the third — profile (10 and 11 classes). In this case, the program for classes 2 to 9 is the required minimum. In the senior classes, in-depth training in informatics on various profiles is carried out. This provides training for professional activities. The topics that have already been covered are discussed in more detail, different classes of programs are studied.

Informatics: Unified State Exam

In this subject, the USE is one of the longestexams, which lasts about 4 hours. In 2014, the minimum passing grade was 40. Preparation should begin long before the day of testing, and high results in this case will be provided.

The tasks on computer science are divided into blocks independing on their complexity. А1-А13 — questions of a base level with a choice from several variants of the answer. For each correct choice, 1 point is assumed. Tasks on computer science В1-В15 are already tasks of increased complexity. Numbers or the last digits serve as a response to them. The most difficult tasks in informatics are C1-C4. It is necessary to give the fullest possible answer to them.

In each version of the USE, computer science tasks are related in one way or another. However, when solving tasks from category C, it is forbidden to use the calculator and the PC.

From Wikipedia, the free encyclopedia

Informatics is the study of computational systems.^[1][2] According to the ACM Europe Council and Informatics Europe, informatics is synonymous with computer science and computing as a profession,^[3] in which the central notion is transformation of information.^[1][4] In other countries, the term «informatics» is used with a different meaning in the context of library science, in which case it is synonymous with data storage and retrieval.^[5]

Different meanings[edit]

In some countries, depending on local interpretations, the term «informatics» is used synonymously to mean information systems, information science, information theory, information engineering, information technology, information processing, or other theoretical or practical fields. In Germany, the term informatics almost exactly corresponds to modern computer science. Accordingly, universities in continental Europe usually translate «informatics» as computer science, or sometimes information and computer science, although technical universities may translate it as computer science & engineering.^[6][7]

In the United States, however, the term informatics is mostly used in context of data science, library science^[5] or its applications in healthcare (health informatics),^[8][9] where it first appeared in the US.

The University of Washington uses this term to refer to social computing.^[10] In some countries, this term is associated with natural computation and neural computation.^[1][11]

The Government of Canada uses the term to refer to operational units offering network and computer services to the various departments.^[12]

Etymology[edit]

In 1956, the German informatician Karl Steinbuch and engineer Helmut Gröttrup coined the word Informatik when they developed the Informatik-Anlage^[13] for the Quelle mail-order management, one of the earliest commercial applications of data processing. In April 1957, Steinbuch published a paper called Informatik: Automatische Informationsverarbeitung («Informatics: Automatic Information Processing»).^[14] The morphology—informat-ion + —ics—uses «the accepted form for names of sciences, as conics, mathematics, linguistics, optics, or matters of practice, as economics, politics, tactics»,^[15] and so, linguistically, the meaning extends easily to encompass both the science of information and the practice of information processing. The German word Informatik is usually translated to English as^[16] computer science by universities or computer science & engineering by technical universities (German equivalents for institutes of technology). Depending on the context, informatics is also translated into computing, scientific computing or information and computer technology. The French term informatique was coined in 1962 by Philippe Dreyfus.^[17] In the same month was also proposed independently by Walter F. Bauer (1924–2015) and associates who co-founded software company Informatics Inc. The term for the new discipline quickly spread throughout Europe, but it did not catch on in the United States. Over the years, many different definitions of informatics have been developed, most of them claim that the essence of informatics is one of these concepts: information processing, algorithms, computation, information, algorithmic processes, computational processes or computational systems.^[18][1]

The earliest uses of the term informatics in the United States was during the 1950s with the beginning of computer use in healthcare.^[19] Early practitioners interested in the field soon learned that there were no formal education programs, and none emerged until the late 1960s. They introduced the term informatics only in the context of archival science, which is only a small part of informatics. Professional development, therefore, played a significant role in the development of health informatics.^[19] According to Imhoff et al., 2001, healthcare informatics is not only the application of computer technology to problems in healthcare, but covers all aspects of generation, handling, communication, storage, retrieval, management, analysis, discovery, and synthesis of data information and knowledge in the entire scope of healthcare. Furthermore, they stated that the primary goal of health informatics can be distinguished as follows: To provide solutions for problems related to data, information, and knowledge processing. To study general principles of processing data information and knowledge in medicine and healthcare.^[20][21] The term health informatics quickly spread throughout the United States in various forms such as nursing informatics, public health informatics or medical informatics. Analogous terms were later introduced for use of computers in various fields, such as business informatics, forest informatics, legal informatics etc. These fields still mainly use term informatics in context of library science.

Informatics as library science[edit]

In the fields of geoinformatics or irrigation informatics, the term -informatics usually mean information science, in context related to library science. This was the first meaning of informatics introduced in Russia in 1966 by A.I. Mikhailov, R.S. Gilyarevskii, and A.I. Chernyi, which referred to a scientific discipline that studies the structure and properties of scientific information.^[22] In this context, the term was also used by the International Neuroinformatics Coordinating Facility. Some scientists use this term, however, to refer to the science of information processing, not data management.^[23]

In the English-speaking world, the term informatics was first widely used in the compound medical informatics, taken to include «the cognitive, information processing, and communication tasks of medical practice, education, and research, including information science and the technology to support these tasks».^[24] Many such compounds are now in use; they can be viewed as different areas of «applied informatics«.

Informatics as information processing science[edit]

In the early 1990s, K.K. Kolin proposed an interpretation of informatics as a fundamental science that studies information processes in nature, society, and technical systems.^[22]

A broad interpretation of informatics, as «the study of the structure, algorithms, behaviour, and interactions of natural and artificial computational systems,» was introduced by the University of Edinburgh in 1994. This has led to the merger of the institutes of computer science, artificial intelligence and cognitive science into a single School of Informatics in 2002.^[25]

More than a dozen nearby universities joined Scottish Informatics and Computer Science Alliance. Some non-European universities have also adopted this definition (e.g. Kyoto University School of Informatics).

In 2003, Yingxu Wang popularized term cognitive informatics, described as follows:^[26]

Supplementary to matter and energy, information is the third essence for modeling the world. Cognitive informatics focuses on internal information processing mechanisms and the natural intelligence of the brain.

Informatics as a fundamental science of information in natural and artificial systems was proposed again in Russia in 2006.^[27]

In 2007, the influential book Decoding the Universe was published.

Former president of Association for Computing Machinery, Peter Denning wrote in 2007:^[28]

The old definition of computer science — the study of phenomena surrounding computers — is now obsolete. Computing is the study of natural and artificial information processes.

The 2008 Research Assessment Exercise, of the UK Funding Councils, includes a new, Computer Science and Informatics, unit of assessment (UoA),^[29] whose scope is described as follows:

The UoA includes the study of methods for acquiring, storing, processing, communicating and reasoning about information, and the role of interactivity in natural and artificial systems, through the implementation, organisation and use of computer hardware, software and other resources. The subjects are characterised by the rigorous application of analysis, experimentation and design.

In 2008, the construction of the Informatics Forum was completed. In 2018, the MIT Schwarzman College of Computing was established. Its construction is planned to be completed in 2021.

Controversial fields[edit]

• evolutionary informatics — a new field that comes from the concept of an intelligent design. According to Evolutionary Informatics Lab, evolutionary informatics studies how evolving systems incorporate, transform, and export information.^[30] In 2017, the influential book «Introduction To Evolutionary Informatics» was published.^[31]

What Does Informatics Mean?

Informatics is the study of the behavior and structure of any system that generates, stores, processes and then presents information; it is basically the science of information. The field takes into consideration the interaction between the information systems and the user, as well as the construction of the interfaces between the two, such as the user interface.

Techopedia Explains Informatics

The term informatics was first coined by a German computer scientist by the name of Karl Steinbuch in 1957 through his published paper titled «Informatics: Automatic Information Processing.» Informatics was then used interchangeably with computer science as its German word «Informatik» is usually translated to English as computer or computing science. In 1994, the University of Edinburgh in Scotland formed a grouping that is now its School of Informatics and gave the general meaning of informatics as «the study of the structure, algorithms, behavior, and interactions of natural and artificial computational systems.» The meaning gained widespread use in the UK.

There is still no universal meaning for informatics as different organizations, educational or otherwise, have their own meaning for it. But all of these different ways of defining informatics still adhere to the same core that it is about the study and application of information and information technology in everyday processes.

Computer Science

Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.

Informatics

Informatics is a branch of information engineering. It involves the practice of information processing and the engineering of information systems, and as an academic field it is an applied form of information science. The field considers the interaction between humans and information alongside the construction of interfaces, organisations, technologies and systems. As such, the field of informatics has great breadth and encompasses many subspecialties, including disciplines of computer science, information systems, information technology and statistics. Since the advent of computers, individuals and organizations increasingly process information digitally. This has led to the study of informatics with computational, mathematical, biological, cognitive and social aspects, including study of the social impact of information technologies.

It is for sure time and place dependent, after further research it seems that the German term Informatik was a synonym of the Computer Science at first, was adapted virtually everywhere, but evolved since 1956, and diverged with meaning, but it is still overlapping. Tt seems that currently Informatics is used more as applied Computer Science (ref: search engine coin toss).

The IT (Information Technology) in some languages has broader meaning, and simply merges telecommunication with computer sciene and informatics. Unfortunately this is not well-defined term, it is part of the language so it may vary in time up to the moment when people think it is too broad and start some finer classification.
