INFORMATION AND INFORMATION PROCESSES

sign
sign system
natural languages
formal languages

Sign is a placeholder for an object.

A sign (set of signs) allows the transmitter of information to evoke an image of an object in the mind of the recipient of the information.

Sign - this is an explicit or implicit agreement to attribute a certain meaning to some sensory perceived object.

Pictogram

The shape of the sign allows you to guess its meaning.

Symbol

The connection between the form of a sign and its meaning is established by agreement.

Signs and sign systems

People use individual signs and sign systems.

Sign system is determined by the set of all signs included in it (the alphabet) and the rules for operating these signs.

Language as a sign system

Communication between people can take place orally or in writing using appropriate audio or visual cues.

The concept of information is a fundamental concept in computer science. Any human activity is a process of collecting and processing information, making decisions based on it and implementing them. With the advent of modern computer technology, information began to act as one of the most important resources for scientific and technological progress.

The term "information" comes from the Latin informatio explanation, presentation, awareness. The Encyclopedic Dictionary (M.: Sov. Encyclopedia, 1990) defines information in historical evolution: initially information transmitted by people orally, in writing or in other ways (using conventional signals, technical means, etc.); since the middle of the 20th century, a general scientific concept that includes the exchange of information between people, man and machine, the exchange of signals in the animal and plant world (transfer of characteristics from cell to cell, from organism to organism).

Associated with the concept of information are concepts such as signal, message and data. A signal (from the Latin signum sign) is any process that carries information. A message is information presented in a specific form and intended to be transmitted. Data is information presented in a formalized form and intended for processing technical means, for example, a computer.

Classification: Identification of items to be coded. It includes those details - characteristics that are used to create groupings. For each nomenclature, a complete list of all items to be coded is compiled. At the same time, the logical dependence of the various features in the nomenclature in question is observed. For example, when coding a territory, districts are arranged by region. Such an ordered list is called nomenclature. Each nomenclature provides for a certain number of reserve positions in case new objects appear. Thus, classification consists of distributing the elements of a set into subsets based on features and dependencies within the features.

When creating IR automated information networks the following work is performed: The composition of economic tasks and the system of indicators for each level of processing are determined; The composition and methods of information exchange between different levels of processing are established; An information fund is being created and distributed; Various forms of information input on a PC are created, taking into account multi-level data processing; The issues of using various types of classifiers are considered and the creation of local classifiers of economic information is ensured; Various forms of information output are created; Issues of information and reference services for users, construction of standard queries are being developed; Automated IT is being created that ensures direct contact between the user and the PC (development of a dialogue script, structure, menu); Issues of organizing office work for management activities on a PC and monitoring the execution of documents are being worked out; Information interaction with the external environment is created based on the organization of e-mail.

The creation of IO is carried out during the preparation of a technological project and involves the preparation of instructions to users on the application of the main provisions of IO in their practical activities related to the processing of economic tasks on a PC. These are: Instructions for preparing documents for machine processing and encoding them; Instructions for processing an economic problem on a PC - entering a program, correcting information arrays, correcting information, loading into a database, organizing queries, obtaining output data.

Information is contained in human speech, texts of books, magazines and newspapers, radio and television messages, instrument readings, etc. A person perceives information using the senses, stores and processes it using the brain and central nervous system. The transmitted information usually concerns some objects or ourselves and is associated with events occurring in the world around us.

Within science, information is a primary and indefinable concept. It presupposes the presence of a material carrier of information, a source of information, an information transmitter, a receiver, and a communication channel between the source and the receiver. The concept of information is used in all areas: science, technology, culture, sociology and Everyday life. The specific interpretation of the elements associated with the concept of information depends on the method of a particular science, the purpose of the study, or simply on our ideas.

A narrower definition is given in technology, where this concept includes all information that is the object of storage, transmission and transformation. The most general definition takes place in philosophy, where information is understood as a reflection of the real world. Information as a philosophical category is considered as one of the attributes of matter, reflecting its structure

There are two forms of information presentation: continuous and discrete. Since signals are carriers of information, physical processes of various natures can be used as the latter. For example, the process of electric current flowing in a circuit, the process of mechanical movement of a body, the process of light propagation, etc. Information is represented (reflected) by the value of one or more parameters of a physical process (signal), or a combination of several parameters.

In Fig. 1.1 shows in the form of graphs: a) a continuous Hnn signal in level and time; b) signal Hdn, discrete in level and continuous in time; c) continuous in level and discrete in time signal HND; d) signal Hdd, discrete in level and time. Fig Types of information processes

Finally, all the variety of information surrounding us can be grouped according to various criteria, that is, classified by type. For example, depending on the area of origin, information reflecting processes and phenomena of inanimate nature is called elementary, animal processes and flora biological, human society social.

According to the method of transmission and perception, the following types of information are distinguished: visual transmitted by visible images and symbols, auditory by sounds, tactile sensations, organoleptic by smells and taste, machine generated and perceived by computer technology, etc.

The amount of information is the numerical characteristic of a signal, reflecting the degree of uncertainty (incompleteness of knowledge) that disappears after receiving a message in the form of a given signal. This measure of uncertainty in information theory is called entropy. If, as a result of receiving a message, complete clarity is achieved on some issue, it is said that complete or exhaustive information has been received and there is no need to obtain additional information. And, conversely, if after receiving the message the uncertainty remains the same, then no information was received (zero information).

The above considerations show that there is a close connection between the concepts of information, uncertainty and choice. Thus, any uncertainty presupposes the possibility of choice, and any information, reducing uncertainty, reduces the possibility of choice. With complete information there is no choice. Partial information reduces the number of choices, thereby reducing uncertainty.

DURING THE CLASSES

Organizing time.

Teacher: Hello guys. Sit down.

Updating basic knowledge.

Teacher : In previous lessons, we studied various forms of presenting information.

Presentation in progress.

What forms of information presentation do you already know? (numeric, graphic, text)
With what senses can a person perceive written information? ( eye )
Tell us about the text form of presenting information.

(Text is any verbal statement, printed, written, or spoken. Information presented in the form of written text is called textual information.)

Explanation of new material.

Formulation of the lesson topic.

Teacher : Here is text information. Let's read it and try to imagine the picture: ( slide 4)

A fiery glow colored the sky. The surface of the ocean seemed covered with a scarlet silk scarf. The mountains spread like a black stripe on the horizon.

What did you imagine? (students answer)

You see everyone got a different description. Now let's look at the picture painted according to this description. ( slide 4)

Teacher : How do you think it is easier to perceive information:

a) by drawing or by text? (according to the picture)

b) why? (information is clear)

Teacher : Indeed, visual information is easier to perceive. After all, even a baby that is born cannot speak or walk, he perceives the world with my own eyes. Therefore, the topic of our lesson is: “Visual forms of presenting information.”

Write the topic in your notebook.

Teacher : Guys, what do you think is the purpose of the lesson? (get acquainted with visual forms of presenting information, find out whether people need a visual form of presenting information).

Formulation of the problem. Group work.

Teacher: Do we need a visual form of presenting information? And the following experiment will help us figure this out (slide 5).

Teacher: So, let's return to the purpose of our research. What conclusion can we draw?(Students think and offer possible answers.)

Teacher : It is impossible to do without visual forms of presenting information.

Teacher: In your homework, you will be required to complete a task similar to the given ones.

Presentation of new material.

Teacher: So, we found out that a visual form of presenting information is necessary. Let's see what visual forms of presenting information you used and learn about other examples.

Demonstration of presentation, conversation with students.

Teacher: (slide 7) Drawing (picture) is a very popular and accessible form of presenting information.

What can most clearly tell about your travels and holidays?(Photos.)

(slide 8 ) You see on the slide a map of our Tula region. From your natural history lessons, you know that using a map can also provide a lot of information about a given area. Next year you will begin to study a new subject - geography, and in your lessons you will use this very visual form of presenting information.

(slide 9 ) Conventional signs are very common in our lives. Please explain where you might have met or used them.(When the weather forecast is announced, on the road.)

(slide 9 ) We can also get a large amount of information from diagrams. They help you better understand and remember new material. Look at the diagrams. Where do you use them? Come up with a proposal for this scheme.(In Russian language lessons.)

How can you conveniently represent numerical data? The answer lies in the problem. ( slide 10)

Exercise : It is known that someone arranged all the letters of the alphabet in a circle and replaced each letter of the original message with the next one after it. Decode the received encryption:(or using RT: No. 20 P.23)

Answer: D I A G R A M M A.

Teacher : What is a diagram, let’s open the encyclopedic dictionary?(Diagram - a graphical representation of the relationship of some quantities.)

Teacher : Let's find out how you can represent numerical data using a chart. Let's solve the problem: It is known that the life expectancies of animals are different. We will find out what animals we are talking about from the riddles. ( slide 14)

The names of animals appear sequentially on the board, then the years of life:

Elephant – 60
Crocodile – 40
Camel – 30
Bear – 25
Chimpanzee – 60

Teacher: The average life expectancies of an elephant, crocodile, camel, bear and chimpanzee are 60, 40, 30, 25 and 60 years respectively.
Teacher: This data can be presented online diagram.
Teacher: Attention! Only those who will listen carefully will construct the diagram correctly.
Teacher: Let's draw a coordinate system on a squared sheet of paper. Horizontally we will plot the years of life of the animals, and vertically the name of the animal. Let two cells equal 10 years of life.
– Using a ruler, draw 5 horizontal segments (since there are 5 animals), the lengths of which will be 60, 40, 30, 25 and 60 mm, respectively:

Conclusion: The diagram clearly shows the life expectancy of animals.
– The diagram may have a different appearance. If you rotate the coordinate system by 90°, and instead of segments, draw rectangles with equal base lengths and heights corresponding to the numbers 60, 40, 30, 25 and 60. This is called a column diagram. ( slide 15)

Physical education minute. ( slide 16)

Teacher: And now you can rest. Please stand up and leave your desk. Repeat the exercises after me.

We will move our hands -

It's like we're swimming in the sea.
