Computer science is a science that studies the ways and methods of transmitting, processing and analyzing information, as well as working with computers. In the modern world, when technology is becoming more and more popular and in demand, it is impossible to live without computer science. In turn, this science is divided into sections that allow a deeper study of this discipline.
What sections does computer science include?
- Theoretical computer science.
- Applied Informatics.
- Programming.
- Artificial Intelligence.
These main sections of computer science, in turn, are divided into subsections.
Artificial Intelligence
One of the areas of computer science - artificial intelligence - arose not so long ago: in the 70s of the 20th century. However, it is he who significantly affects the development of science as a whole. Based on the approaches of theoretical informatics, artificial intelligence also uses logical means to modernize knowledge. This direction is also associated with cybernetics - a science that studies the laws of control and the relationship of machines and living organisms. The formation of artificial intelligence as one of the branches of computer science was significantly influenced by such sciences and areas as mathematical and applied linguistics, neurocybernetics, as well as homeostatics. They are widely used programming systems.
The purpose of artificial intelligence is to identify the creative abilities of people, their knowledge and skills. If scientists can understand these human secrets, then it will be possible to create artificial systems with their own intelligence. This proves the close connection of this direction and psychology, with the help of which the human essence is known. Specialists working in the field of studying artificial intelligence are interested in cognitive psychology aimed at studying the processes of human cognitive activity.
Psycholinguistics is also important for the development of artificial intelligence. It includes the study of communication methods - both through speech, and gestures and facial expressions.
The use of robotics allows replacing human activities in some industries, where programmed machines - robots will perform their work.
Sections of Theoretical Computer Science
Theoretical computer science is based on the study of mathematical modeling of processing, transmission, use of the information received. This section is the foundation of all science, because it is in it that the whole theory is concentrated. Since most of the information is presented in alphanumeric or dotted form, mathematical logic is widely used in theoretical informatics as a component of discrete mathematics. Also, theoretical informatics is divided into the following areas:
- Computational mathematics - allows you to find solutions to problems using computer programs using and developing special algorithms.
- Theory of information (coding and transmission of information). Here, the information appears in the form of an abstract object that cannot be specified. In this subsection, its history of origin, the laws on the basis of which it can exist or be destroyed are studied.
- System analysis allows you to describe real phenomena, objects, processes using information models. Most often, simulation modeling is used for this, where processes of real objects are reproduced.
- Decision theory is the last section of theoretical computer science. It selects the most acceptable and suitable solutions from the available possibilities by drawing up diagrams. All this is carried out in a conflict and is studied in game theory.
Applied Informatics
Applied informatics is aimed at applying the terms of the theoretical section in solving certain problems in special fields. Achievements of this direction are widely used in scientific activity, in the development of new technologies, in automated systems and their management.
Programming
It is impossible to imagine computer science without programming, which appeared with the advent of computers. Specialists in this field are developing system software that requires the use of special digital languages and helps to develop all other sections of computer science.
