Introduction

this work contains methodical instructions Laboratory work on the discipline "Fundamentals of Information Technologies" and is intended for students in the specialty 230103.02 "Master of Processing Digital Information".

The description of each laboratory work contains: the topic, objectives of the work, the procedure for performing the work, as well as a list of control questions, in order to identify and eliminate the shortcomings in the development of the topic under consideration. For more detailed information on issues under study, a list of recommended literature is given.

Laboratory work number 1

Determination of high-quality and quantitative characteristics on specified conditions

Objectives: master the main approaches to the measurement of information; know the formula for calculating the number of information; be able to solve problems for finding the amount of information using alphabetical and meaningful approaches; To have an idea of \u200b\u200ball methods for finding the number of information.

II. Theoretical material lesson

To date, we have a well-developed theory of quantitative description of information. It is based on a probabilistic statistical approach to K.-E. Shannon, N. this theory Does not take into account the meaningful and value part of the information.

The syntactic approach was a solution to the problems of communication theory.

A probabilistic approach is quite popular in many publications on computer science, so we will discuss in more detail on other theories, less popular, but we think that no less interesting. There are still combinatorial, algorithmic, topological approaches.

To find the amount of information use the formula

2 h. \u003d N,

where n is the number of all possible events;

X is the amount of information contained in this message.

Reducing knowledge uncertainty 2 times contains 1 bit of information. So, as a minimum unit of information, 1 bit of information is used.

Call cases where you have to select one event of two possible. Does this number of events always carry 1 bit information? Why?

III. Practical lessons

At the "Cults" stops, buses are stopped at 2,4,8 and 16 numbers. How many bits of information are the message that the bus number eight approached the stop?

(As the initial amount of possible events, we take a value of 4, that is, 4 types of buses stop at this stop. Bus numbers are not used in the calculations. Since n \u003d 4, 2 h. \u003d 4, then x \u003d 2 bits.)

In the school canteen, two dishes are offered to choose from: soup and pasta with a cutlet. How many bits be charged with a message that the student chose a pasta with a cutlet.

(The number of possible events is two. So n \u003d 2, we substitute in formula 2 h. \u003d 4 and get x \u003d 1 bit.)

To prepare an essay, a student used 16 sources of scientific literature. Only one book turned out to be the most informative. How many bits of information makes a message that quotes were taken from the Encyclopedic Dictionary of Pospelov?

(The number of all possible events is 16, then x \u003d 4 bits.)

1. Higher that the information weight of one symbol is 1 byte (aSCII encoding ), find the information phrase information:
Baikal is the deepest fresh lake in the world.

Given:

i. \u003d 1 byte.
To find:I.

Decision:
The number of characters in this phrase is 45 (counting spaces and punctuation marks).

K \u003d 45. symbols.

I \u003d. 45 bytes.

Answer: The information volume is equal 45 Baita.

2. If the 128 symbolic alphabet is recorded a message from 5 characters, then what is the volume of the message.

Dano.
N \u003d 128-Power of the alphabet (this is uncertainty).

K \u003d 5. symbols.

To find:I.

Decision

2 i \u003d 128

2 i \u003d 2 7

i. = 7

So one character takes 7 bits in memory.

Then 5 characters occupy 35 bits in memory, i.e.

I \u003d k * i

I \u003d 5 * 7

I \u003d. 35 bit
Answer: 35 bit.

3. How much do you need to ask questions to determine the arrival hour of the train?

Given:

N \u003d 24 hours - uncertainty.
Find: I.

Decision:

2 i \u003d 24

4 i.

To determine the arrival hour of the train, you need to ask 5 questions (4 questions will not be enough), in other words, get 5 bits of information.
Answer: 5 bits.

Laboratory work number 9.

Identification and authentication of users and network resources for specified conditions

The usual method of authentication in the Web is a visitors requirement to provide a unique username and password. Authentication is usually used to permit or prohibit access to specific pages or resources. Authentication may be optional or used for other purposes, for example, for personalization.

M. custom authentication of users contains four main elements: user registration, login and output from the system, change passwords and reinstall passwords.

Check in:

To register a user, it is necessary through the form to obtain information about it and place them in the database.

Moreover, PHP -Senarium must check the necessary data entry requirements, for example, the number of characters allowed for input in each field:

if (Strlen ($ UserName) \u003d 16)

echo "Error: the username cannot be more than 16 characters.

Please return to the form and try again. "

exit;

It is also necessary to verify the uniqueness of the username. If the selected username is already involved (the user with that name already exists), then a message type should be issued:

The user with this name already exists. Please return to the form and try again!

To check the uniqueness MySQL query will look like this:

$ Query \u003d "Select * from User WHERE" $ UserName "\u003d UserName" or

$ Query \u003d "Select * from Users WHERE UserName Like"%. $ UserName. "%" " (!!! Both requests work !!!)

When adding a new user to the database, you must first encrypt user passwords, using the SHA 1 () function: For this, MySQL query must be built as follows:

$ Query \u003d "INSERT INTO User Values \u200b\u200b(" $ UserName ", Sha1 (" $ passwd ")," $ email ")";

It should be noted that connecting to the database is implemented through the previously written function. db_coimect ().It simply provides the only storage area of \u200b\u200bthe username and password to connect to the database. Thus, to change the database password, it is enough to upgrade one application file.

Implement a multi-aunt for the provision of goods or services to customers. A multi-agent system must contain several types of agents. For example, agents providing goods or services for a certain value; Agents buying these goods or services; Intermediary agents between the seller agent and agent - the final buyer. Each agent receives initial information from the user. Catching a user and agent occurs using a graphical user interface. One user introduces descriptions of goods and services, and another user enters information about which product or service must be purchased.

Options for individual tasks

Booking airfares, bus or rail tickets . The decision involves two agents. The cashier agent provides information on free tickets and sells tickets. The buyer's agent finds the required flights and book tickets. The schedule is entered by the dispatcher. Information about the required ticket is entered by a customer user. The initial state of tickets is all free.
Booking trips from tourist operators. The seller's agent is a representative of the tour operator and provides information on tourist vouchers. The buyer's agent is a representative of the buyer of a tourist ticket. Information about vouchers is entered by a tour operator. Information about the required ticket is entered by the buyer.

Collection of information for buying a cell phone. The seller's agent is a representative of the seller. cell phones And represents information about models, prices and other properties of phones. The buyer's agent is a representative of the buyer and searches for the purchase of a phone of the required properties. Product information is located in the product catalog and varies by the self-seller. Information about the required purchase is entered by the buyer.
Collection of information for buying furniture. The seller is a representative of the seller of the furniture store and provides information on the product present in the store. The seller user enters information about the proposed product. The buyer's agent is a representative of the furniture buyer. The buyer user informs its agent information about the desired furniture.
Collection of information for buying real estate. The Realter seller is a representative of the real estate company and provides information on real estate facilities, prices and properties. User Realter introduces information about the proposed properties of real estate: apartments, cottages, garages, offices, etc. The Realter-Buyer Agent is a representative of a real estate firm by finding real estate objects for its customers. User Realter in this case transmits information to its agent on the required real estate objects for its customers. The buyer is a representative of the property buyer. The final buyer transmits information to its agent about the required real estate object.
Collection of information for buying a car. The seller's agent is a representative of the car sale salon and provides information about cars. The user seller introduces information about cars sold in the cabin. The buyer's agent is a representative of the car's buyer. The buyer user transmits information to its agent about the required car.
Search for a job. An agent agent is a representative of the personnel agency and provides information on vacancies. An employee of the Agency introduces information on existing job vacancies in the labor market. An employee's agent is a representative of an employee hiring to work. The employee user transmits information to his agent about the required position, level wages, location, working conditions, etc.
Distribution of students on enterprises. Three types of agents participate in the task: an agent agent, an agent responsible for the distribution, a student agent. The tenant agent provides information on the enterprise, positions and working conditions. The agent - responsible for the distribution searches for students distribution. The student's agent provides information on registration, the middle score of the student, its preferences and other information necessary to select the distribution location.

LABORATORY WORK

Work theme : Multimedia information processing technology (presentation).

Purpose of work: Develop practical skills to create presentations, setting the effects of animation, managing a presentation display using hyperlinks.

Tasks:

1. expand and deepen theoretical knowledge of computer science;

2. develop practical skills;

3. Promote the development of interest among students to the subject of "Informatics".

Equipment and software: Personal computer, programMS PowerPoint.

Brief theoretical information

Multimedia technology - Interactive (dialogue) systems, providing simultaneous work with sound, animated with computer graphics, video frames, images and texts.

Interactivity - The ability to dialogue with a user based on a graphical interface with control elements (buttons, text windows, etc.).

Computer presentation It is one of the types of multimedia projects - sequences of slides (electronic cards) containing multimedia objects.

The transition between slides or other documents is carried out using buttons or hyperlinks.

Creating presentations is carried out in the PowerPoint program.

Basic rules for developing and creating a presentation

Font Regulations:

Fonts with serifs are read easier than grotescas (free fonts);
For the main text it is not recommended to use uppercase letters.
The font contrast can be created by: font size, font thickness, drawing, shapes, directions and colors.

Color gamma choices.

The color scheme should consist of no more than two or three colors.
There are non-combined combinations of colors.
Black color has a negative (gloomy) subtext.
White text on a black background is read bad (inversion is badly read).

Rules of the overall composition.

There should be no more than seven significant objects on the lane, as a person is not able to remember at one time more than seven points of anything.
The logo on the strip should be located on the right below (on the left above, etc.).
The logo must be simple and concise form.
The design should be simple, and the text is short.
Images of pets, children, women, etc. are positive images.
Large objects in the composition of any composition look pretty no matter. Arshorny letters in headlines, navigation buttons in 40 pixels height, layout in one column of 600 points wide, separator of one color, stretched to the entire screen - all this gives design a non-professional view.

Uniform style design

style can include: Certain font (headset and color), background color or background drawing, decorative element of small size, etc.;
it is not recommended to use in the style of the presentation of more than 3 colors and more than 3 types of font;
the decoration of the slide should not distract the attention of the listeners from its meaningful part;
all presentation slides must be sustained in one style;

information blocks should not be too much (3-6);
the recommended size of one information block is no more than 1/2 slide size;
preferably the presence on the page blocks with dirty ones (text, graphs, charts, tables, drawings), complementing each other;
keywords in the information block must be allocated;
information blocks are better to have horizontally associated with the meaning of the blocks - from left to right;
most important information should be placed in the center of the slide;
the logic of the presentation of information on slides and in the presentation must comply with the logic of its presentation.
In addition to the correct location of text blocks, you need to not forget about their content - text. In no case should be kept orphographic errors. You should also consider the general rules for designing text.

Teaching student.PC user must:

Comply with the discipline of students in the lesson, "safety regulations" and this instruction;

Perform only the work that is instructed and to which the teacher is allowed;

Do not fulfill orders if they contradict the safety requirements;

In case of or detecting equipment malfunctions to immediately stop working and inform the teacher; The resumption of work is allowed only after the elimination of all malfunctions;

On violations of safety and cases of injury to work nearby, to immediately report computer science teacher and director of educational institution.

Issuance of tasks for learning

Exercise 1. Using the help system, find out the assignment of the PowerPoint toolbar menu items. Replace results in the table.

Task 2. Create a presentation from the Master of Automantage:

Creating a new presentation in PowerPoint

Create a new presentation in several ways.

With the help of the Wizard of the Wizard providing assistance at all stages of creating a presentation. At the final stage of the work, a standardized slide group is created, combined one common theme that you can choose. Each created slide containsfields - aggregatesreplaced by text or other objects.
Using a design template for registration of the created slides of the presentation, professionally similar color, background and font are provided. The design template does not contain samples of slides.
The presentation can be created with a blank sheet. This means that each presentation slide must be developed independently.

Creating a new presentation using the Master of Automantage

With the help of the Autroright Wizard, you can choose the type of presentation created (for example, a business plan, a diploma, or other projects), on the basis of which the application creates a presentation structure.

To create a new presentation, open the panelTask Area → Creating Presentations.To do this, run the menu command.File → Create, or select the menu item. View → Task Areaor View → Toolbar → Task Area.

In the Wizard program you can use the buttons with which the presentations of various categories are created:General, service, projects, businessand Tips from Carnegie.

Complete presentation, including text aggregates that are on each slide, will appear on the structure panel.

Convert a presentation as follows:

replace the standard text in the slides of the template to your text;
going to Slides Sorter Mode, check out the options:

cleansing slides;
standard color schemes;
effects of changing slides and their sound;

write the first slide of the presentation using a sound music file, the second - by sound recording of a speech comment;
check out the variants of the effects of animation of text and graphic slideshow objects;
after the third slide of the presentation, create a new slide by placing it with your own color scheme. Using the autofigurists of the Draw menu, insert the control button to this slide to start the Paint program;
insert the hyperlink in the last slide, allowing you to return to the beginning of the presentation;
save the presentation in your working folder In two formats: Presentations (Pr.PPT) and demonstration (Pr.PPS);
sequentially start the execution of both files, check the differences in launch operations;
check out the options for the selection of individual elements of the slide at the time of its demonstration using the handle, the marker, the marker located in the lower left corner of the slide shown;
set automatic object animation modes and shifting the presentation slides;
run to execute a slide film in presentation mode and adjust the time intervals of the slide shows, the effects of animation and sound;
run to execute a slide film in demonstration mode.

Task 3. Using Power Point, prepare a presentation on the topic "PC hardware". Apply the greatest number opportunities and effects implemented by the program. Provide hyperlinks both within the presentation and external presentations.

Introduction

Modern information management information systems are intended to assist experts, decision makers, in obtaining timely, reliable, in the required number of information, creating conditions for organizing automated offices, conducting computers and communications tools for operational meetings accompanied by sound and video sequence. It is comprehended by the transition to new information technology. The new information technology is a technology that is based on the use of computers, active participation of users (non-professional programming) in the information process, a high level of a friendly user interface, a wide use of user and problem application packages, the ability to access remote databases. and programs thanks to computer networks.

Constantly expanding applications personal computersTheir mass use, including in economic work, has led to the need to form the most effective computing and other organizational technology. Currently, they are created and successfully operating local and multi-level computing networksrepresenting integrated computer data processing systems. Integrated data processing systems are designed as a complex information and technological and software package that supports a single way of presenting data, a single way to interact users with system components and providing information and computational needs of specialists in their professional work. Of particular importance in such systems is attached to the protection of information during its transmission and processing.

Classification of information.

Currently, information is considered as one of the main resources of the Company's development.

Given the features of information, it can be classified according to the following features.

In the field of education:

finance;
marketing;
production;
Scientific research;
labor resources;
social politics;
economic policy.
- At the occurrence:

External information that is divided into incoming and outgoing:

incoming external - information that comes from outside (submitted) and reflects the processes occurring in society;
Outgoing external information is reported to competitors, goes into the authorities of the country, government, ministries and departments, as well as in the media.

Internal information is also divided into incoming and outgoing:

Incoming internal is used by the head for monitoring, establishing standards and reflect of the organization's domestic policy;
Outgoing internal comes from the head when distributing posts and approval of the general internal and external behavioral policy of subordinates.

By technical means:
- television, radio, periodic printing;
- communications, telephone, telegraph, fax;
- computer networks.
Information by the degree of stability:

Static not variable or rarely changing;
Dynamic, varies regularly and is a function of time.

By the nature of the destination:

structured, defining the responsibilities of the management entities;
The reporting, issued in accordance with the deadlines as a report on the execution of the task.

Information according to the degree of processing:

primary, obtained from the original source;
intermediate, obtained from an independent source;
The consolidated, resulting from the processing and analysis of the material.

Collection and registration of data.

The collection of information is the process of targeted extracting and analyzing information about the subject area, in the role of which one or another process can act, etc. The purpose of the collection is to ensure the readiness of information to further promotion in the information process.

Data collection and registration operations are carried out using various means. Distinguish:

mechanized;
automated;
Automatic ways to collect and log data.
- Mechanized - the collection and registration of information is carried out directly by the person using the simplest devices (scales, counters, measuring containers, time metering devices, etc.).
- Automated - the use of machine-readable documents, universal collection and registration systems that ensure combination of operations for the formation of primary documents and obtaining machine carriers.
- Automatic - used mainly when processing data in real time. (Information from the sensors, taking into account the production of production - production, raw materials costs, equipment downtime, etc. - comes directly to the computer).

3. Data transfer.

Data transmission is the transfer of data in the form of binary signals from one point in other telecommunication means, as a rule, for subsequent processing by means of computing equipment.

TECHNICAL DATA Tools include:

data transfer equipment (ADF) that connects tools for processing and preparation of data with telegraph, telephone and broadband communication channels;
Compound interface devices with ADF, which control the exchange of information - data multiplexers.
Recording and transferring information on communication channels to the computer has the following advantages:
simplifies the process of formation and control of information;
The principle of one-time registration of information in the primary document and machine carrier is complied;
A high reliability of information coming into the computer is ensured.

There is a remote data transmission, which is the transmission of data in the form of electrical signals that can be continuous in time and discrete, i.e. Wear a distant character in time. Telegraph and telephone communication channels are most widely used. The electrical signals transmitted by the telegraph communication channel are discrete, and on telephone - continuous.

Depending on the directions for which information is sent, the communication channels differ:

Simplex (transmission goes only in one direction);
half-duplex (at each moment of time either transfer, or receiving information);
Duplex (transmission and reception of information are carried out simultaneously in two opposite directions).

Channels are characterized by data transfer rates, reliability, transfer reliability.

The transmission rate is determined by the amount of information transmitted per unit of time and is measured in bodles (bodes \u003d bit / s).

Speaking about technological operations of collecting, registration, information transmission using various technical means You need to tell a few words about scanning devices.

Entering information, especially graphic, using a keyboard in computer is very laborious. Recently, there have been trends to apply business graphics - one of the main types of information, which requires the operationalization of entering the computer and providing users with the possibility of forming hybrid documents and databases that combine graphics with text. All these functions in PEVM perform scanning devices. They implement an optical entry of information and transform it into a digital form followed by processing.

For IBM PC PC, a PC Image / Graphix system has been developed, designed to scan various documents and their communications transmission. Among the documentary carriers that can be scanned by the system of the system are: text, bar drawings, photos, microfilms. The scanning devices based on PC applies not only to enter text and graphics information, but also in control systems, writing processing, performing various accounting functions.

For the specified tasks, the most applied methods of encoding information by barcodes

Stroke codes have been widely used in trade, and enterprises (in the system of tabletime accounting: when reading from the employee's card, actually spent time, registers time, date, etc.).

Recently, increasing attention is paid to the tactile input devices - the touch screen ("sensory" - sensitive). Tactile input devices are widely used as information and reference systems. common use and automated learning systems. Touch screen It is widely used for stock exchanges (information about the last selling prices for stocks), also in our city of Tuapse, as well as other cities, received widespread use of remote points of payment of a variety of services (communication, utility bills, cash transfer or electronic money etc).

In practice, there are many variants of process data processing processes. It depends on the use of various means of computing and organizational equipment on individual process operations.

The construction of the technological process depends on the nature of the tasks, the circle of users, from the technical tools used, from the data control systems, etc.

Data processing.

Data processing technology is applied at the level of operating (executive) activities of the personnel of low qualifications in order to automate some routine constantly repetitive operations with managerial work. Therefore, the introduction of information technologies and systems at this level will significantly increase the productivity of staff, free from routine operations may even lead to the need to reduce the number of employees.

The technological processing process of information using computers includes the following operations:

reception and packing of documents (checking the completeness and quality of their filling, complete set, etc.);
preparation and control;
Entering data in computer;
Sorting (if there is a need for this);
data processing;
Receiving answers to all sorts of current requests and their design.

An example may be a daily report on cash receipts and issuance by the Bank, formed in order to control the balance of cash, or request to the database on personnel, which will obtain data on the requirements for candidates for the occupation of a particular position.

Many data at the level of operating activities must be maintained for later use or here, or on a different level. Databases are created for storage.

Data output.

The final stage after collecting, registering, transmitting and processing data is their output in one format, as a graphical, tabular or text form. Directly the data output itself can be carried out through electronic devices. These are:

Monitors.

The monitor (display) of the computer is designed to display text and graphics information.

Their advantage is that the display of information occurs in real time, with the ability to view and edit results without the use of additional equipment.

Display display disabilities are impossible to use the results further in the document flow (signing documents, approval by sealing, etc.)

Printers.

The printer (or printing device) is designed to display information on paper media.

All printers can withdraw text, as well as graphic information (drawings, graphics, tables).

The advantage is that the printed document can be lulpted, put a stamp, printing, and put multiple copies in the document work.

disadvantages printed document - Its wear, the impossibility of editing to represent in the clean version.

Plotter.

Plotter is a device for displaying drawings and other information on large format paper.

Advantages and disadvantages of plotters are similar to printers.

Large format printing is both an advantage and disadvantage (the inability to print small formats).

Plotter

Plotter - device for automatic drawing with high accuracy graphic image of functions specified in analytical form.

Apply in cartography, meteorology, when designing, etc. Most of the modern grafteners receive information directly from the computer or use the data stored on intermediate media of information - punctuents, perfocards, magnetic tapes etc.

There are grades designed for the standard paper size (A4 format), and there are grades, outstanding drawings with a size of 2x2 meters and more.

The disadvantage includes their bulkiness.

Conclusion.

For a long time, a person strives to streamline his knowledge and skills, calculate as much as possible ways of development and self-improvement in any form of activity, accumulating a huge number of experience in preserving and multiplying knowledge of various nature.

In order to achieve a person set before any type of activity, it is necessary to know and be able to apply the methods of achieving goals, this knowledge can be found in informational form If you have access to information.

In the light of the above, I would like to say the following - in our age, high technologies are developing very rapidly, which currently allows you to collect, analyze, systematize, process and remove colossal volumes of information. An important role is played by the protection of information, because no in vain, at all times, people are struggling for the right to possess information. This, perhaps, at this stage of human development, is one of the most kind of resources of humanity.
