- To connect to a local network of portable computers, it is often the case to connect without a mouth, if the transfer of data is needed for additional electromagnetic needs. In mouthless local fences, the central fenestration is attached to the access point. Droplets The type of Wi-Fi can protect the transmission speed of data up to 54 Mb / s, the protection can be stored from the number of connected computers and from the access point.

Local Computer Fingering
Computers of the netting for the exchange of information and information spіlnogo vicoristannya resources (printer, modem, disk memory too).
A local grid of common computers is installed in one primitive (new class, office, etc.), in one booth, or some buddies, which are close to being installed. Call the computers for a local mesh of no more than one kilometer. In the case of an increase in the number of victors, there is a special possession.
Local hedges for the way of interaction between computers are subdivided into: peer-to-peer; as seen by the server. Local framing
Peer-to-peer local net The peer-to-peer local net of all computers is equal. Outbuildings You can be connected to any computer in a net.
Aligned with a visible server The structure of a seam with a visible server
Server (in English. Server - service attachment) is a computer, which is used to generate resources between koristuvachami. Server installed tighter processor, the operative disk memory is large, the main part is saved software security that given heirloom, which can speed up all the coriander heels.
As a workstation, you want to become more productive computers with a smaller disk and operative memory.
Client-server technology is implemented in the fences from the vision server. The server is installed on the server PZ: server operating system; WEB-server (intranet organization); proxy server (securing robots with the Internet of workstations); file server (secure access to files) just. On the net from the server
At the workstation, a client program will be installed to secure: an operating system for workstations; kliєntska part of the applied PZ too. On the net from the server
The most widespread are such methods for connecting computers: a bus (as a rule, it is used for peer-to-peer fingering); zirka (vikoristovutsya for any local fancy). Apparatus for securing the hem
Components of a local mesh For organizing a local mesh, it is necessary to install a circuit board in the leather PC and install all computers for an additional special cable.
Some of the components required to connect the computers are already installed on the system board, and the board is not required. There is also a socket for the cable.
Components of local mesh Coaxial cable - transmission speed 10 Mbps. Vita steam - transmission rate up to 100 Mb / s.
Components of a local mesh of the Concentrator (HUB or Switch) - serve to connect computers to a mesh. The hub can be different from the number of connection ports (change from 8 to 32).
Components of local fences The indigenous knowledge of the net in the framing at the victorian HUB is due to the rapidity of the new payment. For Switch, the flexibility of a computer bet is to start a fast payment in pairs (groups).
Program for securing a net For organizing a local net, it is necessary: assign a unique IP address to the skin computer in the working group, and also set the address of the host mask (in some cases, the explicit IP address and address of the host mask may not be set).
The program for securing the hemispheres Tse vikno vikoristovuyutsya for the installation of the name of the computer and the Roboche group
The program for securing the pattern of Dani is victorious to set up an explicit IP address and parameters of the mask.
It’s worthwhile to be victorious to establish the level of access to local resources of the computer.
Local resource. Barred access to the resources of the computer. To secure the availability, it is necessary to install the transfer pump at the position of the Zagalny resource. A home resource. Allowing vikoristovuvati computer resources (disk memory and peripheral attachments - a printer, a modem) for those who use them. For the whole it is necessary to allow Vidkriti special access to the folder. At the same time, it is necessary to provide sufficient access. Access to resources
Moderate access to the resources of the framing Tilka reading Allowing the filing and copying of files and folders. Outside access Allowing all operations on files and folders (transfer, see, redaguvati, change too). Access, which is set up with a password. Tsey mode will be granted access rights for different categories, for example, if you do not read any more access.

Reutov Kur'yanova Olga Oleksiyivna Author: Information about computer fences Regional fences - to unite computers in the boundaries of one region (place, country, continent). Corporate hedge - to combine computers of the same organization in rural areas and places that seize them from unauthorized access (for example, MicroSoft Network). A global computer of a net is a common one, a lot of local, regional and corporate ones, including hundreds of millions of computers (INTERNET). Internet (at the crossbar from the English - with the hemlines) is a gigantic all-round computer of the hemline. Її priznachennya - make sure anyone has permanent access to any information.

MOU ZOSH №6 m. Reutov Kur'yanova Olga Oleksiyivna Author: Permanently connected Asynchronous access via telephone line (ADSL) - the speed of information transmission (512 kb / s), and the only part of the robot is available. Russia has such a way of leaving only to develop. Synchronous access to the visible channel - the channel is visible, the insurance of the robotic speed (from 64 kbit / s to the number of Mb / s). For a private koristuvach in Russia, the road is happy. Connecting through a local border of a booth or a district is not a vimag of high vitrats, but you can go to the information exchange, so you can jump. For perevischennya ts'go obsyagu (traffic) - additional payment. MOU ZOSH No. 6 m. Reutov
Computers of a framing - a connection of computers to exchange information and a special registration of resources (printer, modem, disk memory is too small.).
- Computers of a framing - a connection of computers to exchange information and a special registration of resources (printer, modem, disk memory is too small.).
- A local grid of common computers is installed in one primitive (new class, office, etc.), in one booth, or some buddies, which are close to being installed.
- Call the computers for a local mesh of no more than one kilometer. In the case of an increase in the number of victors, there is a special possession.
- Local patterns for the way of interaction between computers are subdivided into:
- peer-to-peer;
- as seen by the server.
- In the peer-to-peer local grid, all computers are equal. The headquarters attachments can be connected to any computer at the fencing.
- The structure of the framing from the seen by the server
- Server (in English. Server - service attachment) is a computer, which is used to generate resources between koristuvachami.
- The installation server has a tough processor, a large operative disk memory, the main part of the software security is taken care of, which can be used to speed up all the hard work.
- As a workstation, you want to become more productive computers with a smaller disk and operative memory.
- Client-server technology is implemented in the fences from the vision server.
- On the server, the server software will be installed with the following security:
- server operating system;
- WEB-server (intranet organization);
- proxy server (securing robots with the Internet of workstations);
- file server (secure access to files) just.
- At the work station
- stand up to the client PZ:
- operating system for work stations;
- kliєntska part of the applied PZ too.
- On the net from the server
- The most advanced methods for connecting computers:
- bus (call vikoristovutsya for peer-to-peer fingering);
- zirka (vikoristovutsya for any local fancy).
- Apparatus for securing the hem
- The cable runs from one computer to the other, connecting computers and peripheral attachments
- An external cable from one central university must be connected to the skin computer.
- Local components
- For organizing local fences, it is necessary to install a skin PC board and use all computers for an additional special cable.
- Local components
- Some of the components required to connect the computers are already installed on the system board, and the board is not required.
- There are a lot of sockets for mesh cable retouching on the back of the system unit.
- Local components
- Coaxial cable - transmission speed up to 10 Mb / s.
- Vita steam - transmission rate up to 100 Mb / s.
- Local components
- Retail for cables
- for coaxial cable
- for a twisted bet
- Local components
- Concentrators (HUB or Switch) - serve for connecting computers to the hedgehog.
- The hub can be different from the number of connection ports (change from 8 to 32).
- Local components
- There is a great deal of customization in the fancywork at the victorian HUB.
- For Switch, the flexibility of being a computer bet is to start a fast payment in pairs (groups).
- Netting software
- For robots in a local mesh, special software is required to secure it.
- Have operating system Windows
- also є all the necessary installation of a framing.
- Netting software
- For organizing local hedge it is necessary:
- the visibility of the Robocho Group;
- assign a unique IP address to the skin computer in the working group, and also set the address of the host mask (in some cases, the explicit IP address and address of the host mask may not be set).
- Netting software
- Tse vіkno
- victorious
- imeni of the computer
- that Robochoi group
- Netting software
- Dani vikna vikoristovuyutsya for the establishment
- explicit IP address and parameters in the mask
- Tse vіkno
- victorious
- equal access
- to local computer resources
- Local resource. Barred access to the resources of the computer. To ensure the availability of local resources, it is necessary to install a transfer at the location of the Home resource.
- A home resource. Allowing vikoristovuvati computer resources (disk memory and peripheral attachments - a printer, a modem) for those who use them. For all, it is necessary to allow Vidkrittya outside access to the folder. At the same time, it is necessary to provide sufficient access.
- Access to resources
- Access to resources
- Tіlki chitannya
- Allowing the files and folders to be copied or copied.
- External access
- Allowing koristuvachams to visually display all operations on files, folders (transfer, vidalyati, redaguvati, change too).
- Password-based access
- The whole regime is given the right to access, for example, depriving the reader of any additional access.
