The concept of a byte is inextricably linked with the concept of a bit. A bit is the minimum unit of measurement of the amount of information that corresponds to one of the physical states of matter used to encode information. The most striking example is the so-called “blanks” - CDs and DVDs, on which an empty zone is clearly visible where information has not yet been recorded (it looks lighter) and a dark zone where information is recorded. So, the recorded zone consists of two types of grooves, which reflect the laser beam differently. Depending on this, when reading, these different types of grooves are interpreted as a zero and a one. Unwritten space can be interpreted as Null (Nil) - absence of information.

So, a byte is the number of bits that can be processed by one or another type of processor in one clock cycle. Due to the greatest popularity of processors that processed exactly 8 bits of information at a time, a byte is traditionally called a volume of information of 8 bits in size, although in various computer systems there are other byte sizes.
And the number of bits contained in a byte determines the number of variants of numbers that can be encoded using this number of bits using the formula 2 to the power of N, where N is the number of bits contained in a byte. For example, eight bits can encode 2 to the eighth power or 256 numbers, such as the numbers 0 to 255 (unsigned) or -128 to 127 (signed).

The science of computer science deals with the processing of information presented in the form of numbers. Letters are numbers that determine the position of the character image in a certain table (code page). Colors are also represented by a certain number of bits (1, 2, 4, 8, 15, 16 and 24) to display, respectively, 2, 4, 16, 256, 32768, 65536 and 16777216 color images. The number in this case denotes either the color number in a predetermined color palette (1, 2, 4 and 8-bit color), or a combination of the luminous intensity values ​​of the three primary colors, with the help of which the image is formed on the monitor screen - RGB (Red). , Green - green and Blue - blue). This is called an additive system for forming color on a black background. When printing, colors are subtracted from white paper by overlaying turquoise, violet and yellow colors (CMY - Cyan, Magenta and Yellow). To obtain an accurate black color, instead of overlaying all three colors, a separate black color (blacK) is usually used. In a 16-bit color palette, green uses one extra bit because the human eye is most sensitive to green tones.

Therefore, a byte is essentially either a number from -127 to 128, or a number from 0 to 256, or a character code, or a code for one or more color dots, provided the color is represented in 1, 2, 4 or 8 bit format. or the value of one of the three color components when indicating the color of a point in 15, 16 or 24 bit format for representing color.

During the classes

1. Organizational moment.

Hello, please sit down. Let's get ready for active work, put pens and notebooks in front of us and concentrate. Let's start the lesson.

2. Checking homework. Frontal survey. Solving problems using options.

In the last lesson we started studying communication technologies. Let's review the material.

3. Preparing students for active and conscious learning of new material.

When working on a personal computer in offline mode, users can exchange information (programs, documents, etc.) using optical disks and flash memory. However, moving storage media between computers is not always possible and can take quite a long time. It was necessary to look for ways to solve this problem.

4. Explanation of new material.

The creation of computer networks is caused by the practical need of users of computers remote from each other for the same information, quick access to the information resources of other computers, as well as printers and other peripheral devices. Networks provide users with the ability to even simultaneously process the same documents on computers located at a relatively short distance.

Recording the topic in a notebook. Today in class we will get acquainted with the structure of local computer networks.

After studying the topic, you will learn

    what is a computer network;

    about the types, structure, principles of functioning of a computer network;

    what hardware and software are required for the functioning of computer networks;

    how to exchange data on a local network.

A COMPUTER NETWORK is a system of computers connected by information transmission channels.

A local network (within a premises or an enterprise) allows users not only to quickly exchange information, but also to more efficiently use the resources of networked computers: external memory, printing device, scanner and other technical devices, as well as software.

Global networks connect many local networks, as well as autonomous user computers. The size of global networks is not limited. There are corporate, national and international global networks.

A local network is the connection of two or more computers, allowing them to work together with programs and data.

(Write in a notebook.) LOCAL NETWORKS are small computer networks operating within one room, one enterprise.

If there are no special computers on the local network designed to manage the network, then the network is called peer-to-peer. Users independently decide which resources of their computer to make available to other network users. Such networks have one drawback: poor security of information from unauthorized access.

To ensure greater security, one computer is allocated on the local network, on which the most important information is usually stored.

Such a computer is called a server. Access to information on the server is controlled by one person - the network administrator.

The general scheme for connecting computers to a network (topology) may be different.

A variant of connecting computers, when a cable runs from one computer to another, sequentially connecting computers and peripheral devices to each other, is called LINEAR BUS. If each computer is connected to a separate cable from one central node, then a local network of the STAR type is implemented. Typically, with this connection scheme, the central node is a more powerful computer.

There are other MODELS OF DIFFERENT LAN CONFIGURATIONS. A detailed analysis of each of them in class will take a lot of time. I suggest preparing a message for the next lesson.

Local network computers are usually located close to each other, use a common set of network equipment and are managed by the same software package.

Local networks can be either wired or wireless. In wired networks, the connection is made using twisted pair cables. Wireless ones use an access point as a central network device, and each computer must have a special Wi-Fi type wireless network card installed.

In the Windows operating system, computers connected to the local network are displayed in the Network Neighborhood folder.

5. Consolidation of the studied material. Practical work.

Show students the location of the network folder with the task: “Network environment - share on school”, it contains the folder “9th grade” - “Communication technologies” - “PR. How is a local network structured?

Each student at the computer answers a question from the list. (The teacher distributes prepared questions on sheets of paper.) He needs to type the question given by the teacher in Microsoft Office Word and save it in the network folder “Works at school” - “Local computer network” under his last name. The teacher checks the finished files on his computer.

How does a computer network work?

When working on a personal computer in offline mode, users can exchange information (programs, documents, etc.) using floppy disks, optical disks and flash memory. A system of computers connected by information transmission channels is called computer network.

The creation of computer networks is caused by the practical need for quick access to the information resources of other computers, as well as printers and other peripheral devices.

Local networks

Small computer networks operating within one room, one enterprise, are called local networks ( PM).

Local Area Networks (LAN) - these are associations of computers concentrated in a small area, usually within a radius of no more than 1–2 km, although in some cases a local network can be more extensive, for example, several tens of kilometers. In general, a local network is a communication system owned by one organization.

In many schools, computer science classrooms are equipped with local networks.

Every computer or printer connected to a local network must have a network card. The main function of the network card is to transmit and receive information from the network.

Local networks can be either wired or wireless. In wired networks, the connection is made using different types of cables.

There are two types of coaxial cable : thin and thick. These types of cable are similar to standard television cable.

"Twisted Pair" (twisted pair) is a copper-based cable that combines one or more pairs of conductors in a sheath. Each pair consists of two insulated copper wires twisted around each other. Cables of this type often differ greatly in quality and information transmission capabilities.

Shielded twisted pair(Shielded Twisted Pair,STP) Well protects transmitted signals from external radiation, and also reduces power losses in the cable in the form of radiation. The presence of a screen requires high-quality grounding during installation work, which complicates and increases the cost of cable systems.

Cable tounshielded twisted pair(Unshielded Twisted Pair,UTP) are currently the main data transmission medium for non-optical technologies. Good electrical and mechanical characteristics, combined with ease of installation and relatively low cost, make UTP cable ideal for building a horizontal system.

Optical cable can transmit data with very high throughput. Optical fiber has a high capacity for transmitted data and is resistant to electromagnetic and radio frequency interference. Made from a bundle of glass or plastic strands, fiber optic cable uses light to transmit data.

Fiber optic network has a number of advantages over a conventional copper cable network (although a fiber-optic network is more expensive, and fiber is a more fragile material; in addition, fiber-optic cable is more difficult to split than copper).

Firstly, Fiber optic networks carry large amounts of data due to their higher bandwidth.

Secondly, fiber optic cables are thinner and lighter than copper cables and are more noise resistant than them.

Third, data can be transmitted over them in digital rather than analog form.

Fourth, fiber optic cables are free of electromagnetic radiation, which is ideal for meeting the stringent standards required of today's television and computer applications.

All of these advantages are ideally suited to the requirements for transmitting radio and television signals.

On wireless networks An access point is used as a central network device, and each computer must have a special Wi-Fi-type wireless network card installed.

If all computers on the network have equal rights, that is, the network consists only of user workstations, then it is called a peer-to-peer network.

Peer-to-peer networks are used to implement the first of the noted goals - file sharing. Each computer on such a network has its own name.

More oftenLAN with dedicated server are organized according to the following principle: there is one central machine, which is called a file server. Local network users are usually called a work group, and the computers they work on are calledworkstations.

The central machine has large disk memory. It stores software and other information in the form of files that can be accessed by network users.

The name "server" comes from English server and is translated as “service device”.

Server computer - it is a machine that distributes shared resources among many users.

Exist two main goals using local networks:

1) file sharing between network users;

2) use of shared resources available to all network users: large disk space, printers, centralized database, software and others.

Bus A single cable is used along which all computers on the network are connected. A terminator is needed to absorb the transmitted signal at the ends. Simplicity If one computer fails, this will not affect the operation of the others. At any given time, only one computer can transmit data. A broken cable leads to the termination of the network. If there are a large number of computers, the network works slowly. Disadvantages: Advantages: terminator terminator Network topology - general connection diagram computers on the network

Free medical care under compulsory health insurance in Russia is provided in accordance with the compulsory medical insurance programs: Basic and Territorial.

The basic compulsory medical insurance program is developed and approved by the Government of the Russian Federation. In 2007, free medical care in Russia is provided in accordance with Decree of the Government of the Russian Federation of December 30, 2006 N 885 “On the Program of State Guarantees for Providing Free Medical Care to Citizens of the Russian Federation for 2007.” The territorial is developed and approved by the administration of the constituent entity of the Russian Federation.

The basic compulsory medical insurance program includes a minimum list of requirements for free medical care provided at the expense of compulsory medical insurance funds, which is mandatory throughout Russia. The territorial compulsory health insurance program is a list of requirements mandatory for the entire territory of a constituent entity of the Russian Federation. At the same time, the types, volumes and conditions for the provision of medical services within the framework of the Territorial Compulsory Medical Insurance Program may differ in each subject, but they cannot be lower than the level of the Basic Program.

Moscow city compulsory medical insurance program

In the capital, medical care to citizens insured under compulsory medical insurance is provided in accordance with the Moscow city compulsory medical insurance program (hereinafter referred to as the compulsory medical insurance program), which is an integral part of the currently operating Territorial program of state guarantees for the provision of free medical care to the population of the city of Moscow (approved by the Decree of the Moscow Government dated 07.03 .2006 N 157-PP "On the City Targeted Health Care Development Program "Capital Health Care" for 2006-2007."

Its goal is to provide citizens insured under compulsory medical insurance with free medical care of a guaranteed volume and appropriate quality in healthcare institutions and organizations operating in the compulsory health insurance system of the city of Moscow.

Local computer networks

When working on a personal computer in offline mode, users can exchange information (programs, documents, etc.) using floppy disks, optical disks and flash memory. However, moving storage media between computers is not always possible and can take quite a long time.

The creation of computer networks is caused by the practical need for quick access to the information resources of other computers, as well as printers and other peripheral devices.

A local network (Fig. 6.2) connects computers installed at a relatively short distance from each other (in the same room or building).

For example, computers in a school computer lab are usually connected to a local network, and in a school building several dozen computers installed in subject rooms can be connected to a local network.

Peer-to-peer and server-based networks. In small local networks, all computers usually have equal rights, i.e., users independently decide which resources of their computer (disks, folders or connected printers) to make available to other network users. After this, users working on other computers on the network can use the resources of someone else's computer as if they were their own. As a result, the main disadvantage of such peer-to-peer local networks is the weak security of information from unauthorized access.

In order to ensure greater information security, one of the computers on the local network can be designated as servers, where the most important information is usually stored. The rules for access to this information are set by one person - network administrator.

Folder Network Neighborhood. Computers connected to the local network are included in the folder network hierarchical file system (Fig. 6.3).

Click on the icon network, located on Desktop, opens a window containing folders of computers connected to the local network.

Each of the network computers is also a folder, which in turn contains disk folders. If access to the disks and folders of the computer or to the connected printer is granted, then any network user can use them as their own (copy, delete or rename folders, print to a printer).

Each computer connected to a local network must have a network card (Fig. 6.4), the main function of which is to transmit and receive information from the network.

Connecting desktop computers is usually done using cable (electrical or optical). To connect laptops and pocket computers, a wireless connection is often used, in which data is transferred using electromagnetic waves.

Control questions

1. What additional features are provided to users when working on computers connected to a local network, compared to working on a standalone computer?

2. What is the difference between peer-to-peer LANs and server-based networks?

Tasks for independent completion

6.2. Selective response task. The Network Places folder contains:
1) folders of computers connected to the local network;
