Good day! I am the official representative of Olga Yurievna Guseva.
Olga Yurievna since August 2017 worked in the shop of LLC "CSN-CFD", located at the address: Moscow, st. Lyublinskaya, 102 a, in the position of a seller-cashier. In February 2018, she was dismissed under the influence of her immediate supervisor in accordance with paragraph 3 of Part 1 of Art. 77 Labor Code Russian Federation(on on their own).
This decision was not her initiative. The immediate leader Kuchenov Aleksandr Olegovich (born 12/18/1989) forced him to write a letter of resignation of his own free will, threatening otherwise to be fired under the article for non-fulfillment of official duties.
From the very beginning of work on the part of the deputy manager Kuchenov A.O. (who since January 2018 became the manager of the store) there was a personal hostility towards Olga Yuryevna, expressed in constant nagging. The leader put pressure on her. At the end of 2017, in an attempt to force the plaintiff to resign of her own free will, he repeatedly fined her. Realizing that the methods of psychological bullying are not effective, the manager invited her to his office, where he provided her with a standard letter of resignation of her own free will, and forced her to fill it out.
In violation of Art. 80 of the Labor Code of the Russian Federation, Kuchenov Alexander Olegovich formalized his dismissal on the next working day. The leader did not give time to find new job, but in fact, he simply put the employee, who always conscientiously performed his labor duties and loves his job, caring for her, out the door, putting her in a difficult financial situation.
The Labor Code of the Russian Federation establishes that an employee has the right to terminate labor contract by notifying the employer about this in writing no later than two weeks in advance. This period is given, among other things, so that the employee has the opportunity to withdraw his application at any time before the expiration of this period.
There is a clear violation of the legislation of the Russian Federation by Aleksandr Olegovich Kuchenov.
Olga Yurievna did not plan to quit because she was interested in her work. She would like to continue to work and develop in this company, about which she repeatedly spoke to the manager, and asked him to help her in this, asked to undergo further training.
Evidence supporting the circumstances illegal dismissal the plaintiff are:
1. Video recording from surveillance cameras in the store located at the address: Moscow, st. Lyublinskaya, d. 102 a, from the warehouse of goods and materials and from the office of the manager, where Olga Yuryevna was recorded crying after the message that she needed to quit of her own free will.
2. The fact of a prompt appeal to the State Labor Inspectorate in Moscow.
3. The fact of a prompt appeal on this fact to the superior manager - the director of LLC “CSN-CFD”.
4. The fact of going to court.
It should be noted that Olga Yuryevna is not the first to be fired in this way for recent times.
According to Art. 394 of the Labor Code of the Russian Federation, in the event that dismissal or transfer to another job is recognized as illegal, the employee must be reinstated in his previous job.
The body considering the individual labor dispute decides to pay the employee the average earnings for the entire period of the forced absence.
The unlawful dismissal caused the former employee significant moral suffering, expressed in worries about the lack of any earnings, the fear that she would not be able to quickly find another job and would be left without a livelihood, and therefore would find herself in a difficult financial situation. In addition, Olga Yuryevna has a dependent minor child, who is being raised alone.
I ask you to consider this appeal as an official statement for conducting an internal audit, recognizing the fact of illegal dismissal of an employee and the need for her to be reinstated at work.
Respectfully yours, T.N. Rakhmilova (representative of Guseva O.Yu.).

DNS (domain name service) is the cornerstone comfortable work on the network, a kind of "layer" between and user-understandable "alphabetic" site names.

After all, the expression “I went to 87.240.131.119” when using “vk.com” sounds at least ridiculous, although for a computer these addresses are identical: enter this ip-shnik in the address bar, and you will be taken to a familiar resource. And in this article we will analyze how a dns server works and why a dns server is needed in the global and local information network.

What is DNS and domains on the network?

The DNS server provides the conversion of an IP address to a domain name and vice versa, receiving data for conversion from its own database - that is, all DNS servers in the world store information about all computers and servers in the information network. This is achieved by "separation of duties" - the structure of the DNS in the network includes domains and subdomains, zones and nodes.

Domain is the very "literal" name of the site. For example, "wikipedia.org", although "wikipedia" is already a subdomain of ".org". And "ru.wikipedia.org" as well.

As far as DNS is concerned, each subdomain is managed by its own DNS server, conventionally called a "zone," and each networked computer, printer, or server is managed by a node. The zone is responsible only for computers in its network, and stores information only about these resources

If you need to make a request from an upstream DNS zone to a downstream one, then the DNS-1 server will contact DNS-2 directly, which will already forward the request to the required host [node].

DNS server assignment in the local network

Understand what dns is, and how a dns server works in local network you can use a specific example.

Suppose you have an office with a network of 20 computers for workers, a separate server with a database, and a separate machine with a role and DNS server.

The local network itself, which is not yet connected to the global network, we will call "neboley.ru". DHCP - service on "serv2" automatically sets after which they can communicate with each other and with the web server using ip-addresses.

If you want to assign a name to each computer and device on the network, you will need to configure DNS.

Fortunately, everything for configuring the client side of DNS is provided in Windows and most Linux systems, and you only need to register the authoritative DNS IP address of the local DNS server for each network computer - note, not the server of the provider or Google, but that DNS machines running on the local network.

Also, do not forget to allow on each computer to automatically add resource records about itself to the DNS server database and make each computer a part of the "neboley.ru" domain.

For example, in Windows OS, you can add a machine to the domain network in the "Computer Properties", where the Computer name is already written (for example, "comp1-andrey" or "annaPC").

After adding to the network, it will be annaPC.neboley.ru, and when the record about this machine appears in our DNS database, Andrey, sitting at “comp1-adndrey.neboley.ru”, will be able to contact Anya, who is sitting at “annaPC. neboley.ru ", and not with the unnamed" 192.168.43.19 ".

However, the tasks are so simple dns server are resolved only in the local network. If you decide to connect to the global Internet, then, firstly, you will need to register “neboley.ru” with a domain registrar so that the higher-level DNS server knows that “such and such an IP wants to be called by name and to nobody else. they didn’t give a name ”, and everyone on the Internet could access information on your server, or to network devices.

And secondly - already for the DNS server of your network, you need to set the authoritative provider or DNS servers Google, in which the database is much larger than your 20 PCs. In this case, if a computer on the network wants to go to vk.com, your local network DNS server will forward a request with this name up the chain, and having received an IP address, it will redirect the PC to it and write the information in its own cache.

The shops

DNS

DNS is a major retailer focusing on low prices. In this article, we will consider the convenience of buying a smartphone in the online store of this retailer.

First store DNS (Digital network system) was opened in Vladivostok in 1998 - almost immediately after the default. The outlet specialized in the sale and assembly of personal computers. Later, the range of goods began to expand, and the business clearly went up the hill. Since 2005, the company began to conquer the latitudes of Russia, opening stores in many other regions of the country. The company also includes a factory that produces computers and some other electronics under its own brand, and now under the brand name DEXP.

Initially, it was possible to purchase goods in DNS only by visiting point of sale... But gradually more and more Russians began to receive high-speed Internet access. In this regard, the official website of the retailer began to develop, imperceptibly turning into a full-fledged online store. With its help, you can easily find out whether there is necessary thing in any of 1300 existing stores DNS. But let's take a closer look at the site.

Appearance DNS online store has not changed for several years, which cannot but please regular customers. From time to time, only light edits are introduced, to which users quickly get used to. For example, before the list of products in each category was quite dense, as a result of which a huge number of devices were placed on the page. Now the browser displays about 8-9 products, but at the same time you can immediately see the number of stores in which the device is available. Also, under the name of the device, there was a place for squeezing out technical characteristics... There is also the possibility of changing the presentation of goods - you can make the fields even larger and filled with information, or turn the page into a kind of grid of four columns.

All products can be grouped. In particular, it is possible to sort them by price, name, number of reviews and rating. You can also group devices according to their specific characteristics. For example, for TVs, this can be the screen diagonal, its resolution, the number of HDMI ports, and other specifications. There is another sorting method, which is to select specific stores. For example, you do not want to bring a TV set from the other side of the city - then just check the store closest to you. Finally, you can quickly remove to the end of the list products that are in this moment not available.

By the way, the DNS-Shop site will not display products that are available only in stores located thousands of kilometers from you. Here you can see the devices that will be brought to you in 6 days, but nothing more - they are located in the regions adjacent to you.

On the left side of the screen, when you are in the directory, there are more exact ways sorting. Here you can select specific manufacturers, indicate the range of screen diagonals you are interested in, mark the required display resolution and perform other actions. All this allows you to find a TV, smartphone or any other device with exactly the characteristics that you require. As in other online stores, you can also enter the approximate amount that you are willing to spend on a purchase here.

At the bottom of the left column with the characteristics you need, there is an Advanced Search link. It works like Yandex.Market. By clicking on the link, you will be taken to a page with a mass of all kinds of specifications - from manufacturer, cost and display diagonal to video format, degree of security and dimensions. With all these filters, you can easily find a smartphone that perfectly suits your expectations. Then it remains only to familiarize yourself with each model that the site will give you.


Assortment of goods and catalog

The number of smartphones present in DNS stores is incalculable. You yourself can see the list of companies in the screenshot above. During the price war in 2015-2016, Samsung products did not disappear from here, unlike Euroset and Svyaznoy. Nai big amount of sales in DNS can boast budget devices... But top-end models are also selling quite well, although discounts are rarely provided.

By the way, in 2017, the retail chain created a map of profitable purchases. ProZapass... How many points will be credited to it is indicated under the price of the product. One point is equal to one ruble of discount for the next purchase.

If you click on any product, you will be taken to the page with its description. About half of this page is occupied by a block with photos, a price tag, average mark, an indication of the availability in stores in your city, the buttons "Buy" and "Add to comparison", as well as information about the warranty period and the country of manufacture.

The lower block is divided into six tabs. By default, " Description". There is a sheet of text here, which is sometimes physically difficult to read. Here are the main specifications for the camera, processor, LTE support and battery. In some cases, below is a description from the manufacturer, actually copied from its official website.

The next two tabs are “ Specifications" and " Reviews". The first contains all the main specifications. They cannot be called too detailed - for example, DNS almost never indicates the pixel size of the built-in camera module. But the list is not insufficient either, since it looks more complete than what the aforementioned Yandex.Market provides. However, it all depends on the specific smartphone model - budget models are described in less detail. As for the " Reviews», Here users registered on the site share their impressions. If several complaints have been sent to a particular review, then it is sent to the very end, and its font becomes translucent. This allows you to limit your attention only to useful reviews.

The fourth tab is called " Comments (1)". In it, registered users briefly speak about the device, and sometimes ask something. Although, in theory, questions should be asked in the sixth tab of the same name. Finally, the " Reviews"Contains links to text and video reviews. Users add the links themselves, thus earning special points from the DNS Experts Club. Some of the more adventurous users write their own reviews.

Separately, it should be said about the photographs. As expected, the devices are depicted against a crystal clear white background. The DNS tries to photograph all sides of a smartphone or any other product. Often you can even look at the packaging and packaging! And for some time now in the block with photos there is a link to a video with unpacking a smartphone. This process, by the way, takes three to four minutes, and music sounds in the background - everything important facts about the device are provided in the form of captions.

The only downside to the product information page is the lack of a 3D image of the device. In some other online stores, you can use the mouse to rotate the device around its axis, imagining that it is in your hand. There is no plugin with such a function here. But it pays off with a large number of photos from different angles and the presence of a high-quality unboxing video.

Below the warranty information, you can see the link “ Choose an accessory". It really works! Pressing a button immediately displays all kinds of covers, virtual reality glasses, headsets and memory cards.

Prices and available payment methods

We started this review of the DNS online store by mentioning its aggressive pricing policy... The cost of many smartphones is really lower than in M.Video, Eldorado, or even more so. At the same time, there are no problems with the guarantee - if necessary, the goods will be replaced or the money returned. Interestingly, returned devices are rarely shipped to their manufacturer. Much more often they are repaired and sold in the same retail stores- on the counter with discounted goods.

It should be noted that the price in DNS for flagship and very popular smartphones is often the same as in other large retail chains. But the accessories are a little cheaper.

What is the reason for the low prices? There are no miracles here. If all sorts of "Eldorado" and "M.Video" focus on their bonus cards, then the DNS decided to immediately offer the buyer a product at a low cost. That is why bonuses to the ProZapass card are rarely provided - this item can be seen under the price of only some devices. Also, a company from Vladivostok was repeatedly accused of being cunning at customs, indicating a lower cost of goods. This allows you to pay less taxes, thereby achieving a lower price on the counter.

DNS is more of a retail chain than an online store. Therefore, there are very few payment methods available here:

  • Cash- payment takes place at the checkout of the store when you come for the goods.
  • Bank card- presented at the store's checkout, MasterCard, VISA and Zolotaya Korona systems are supported. You can also pay for the purchase directly on the website, even before receiving the goods.
  • Yandex money- with their help, you can make an advance payment.

DNS is a large trading network, so you can easily apply for a loan right in the store or even on the website. Partner banks in each region of Russia may have their own trading network, so we will not list them here.

Delivery of goods

In terms of delivery of purchased items, DNS is similar to M.Video and other large retailers. It is almost impossible to familiarize yourself with all the conditions in advance. And in every city, delivery of goods can cost different money. After all, it is one thing to deliver a refrigerator to a resident of Kirov, and quite another to provide it to a Muscovite. The sizes of cities are very different, therefore the prices are completely different.

You can find out some delivery conditions regarding your city on the DNS-Shop website. But even so, you will not find out the exact cost of delivery, since it can be completely different, depending on the type of purchased product. The easiest way to pick up a smartphone is from a DNS store yourself. Even in the aforementioned Kirov, there are already seven of them - one of them will definitely be located close to your home. To receive the goods, you will only need to give the order number. If a prepayment was made, then you may be asked for a passport or phone number. Shops are usually open from 9 or 10 in the morning until 20:00, and some of them even a little longer.

Separately, mention should be made of a store such as DNS-Technopoint... This is the so-called online discounter. In fact, he represents one large warehouse with a cash register and computers, with the help of which the order is placed. DNS-Technopoint has its own website, the prices are lower - we recommend using it. In this case, the account on the DNS-Shop and DNS-Technopoint sites is shared.

Summary

In terms of shopping convenience, DNS outperforms almost any online store. And this should not be surprising, because a lot of money has been invested in the development of this trading network.

Let's get acquainted with the main advantages of the DNS-Technopoint or DNS-Shop website (they are made in the same style and use a single database, so you can consider them together):

  • Possibility of ordering goods without registration. Although an account on the site will not bother you, it will make it easier to receive bonuses, as well as allow the system to enter your details automatically and keep a history of purchases.
  • Wide range of. Here, trading is not limited to smartphones, smartwatches and tablet computers. DNS stores sell video cards, vacuum cleaners, coffee makers, pellet removers, and more.
  • Easy loan processing. If you do not have the required amount, then it is enough to use the corresponding option. Online loan is also available here.
  • You can arrange home delivery. This applies not only to all kinds washing machines and refrigerators. The smartphone will also be delivered to you for an additional payment - the courier will do it.
  • Perfectly implemented catalog. Adequate sorting by the most different characteristics, and each product is supplied with a lot of information.
  • Low prices. The retailer tries to keep prices lower than its main competitors.
  • Regular discounts. From time to time, the trading network holds large and not so sales. This allows you to profitably purchase a smartphone, PS4 game or something else.

The trading network also has disadvantages:

  • Not a large number of stores. Of course, DNS is present not only in regional centers. But, for example, in the Kirov region, shops can only be found in Kirov and Kirovo-Chepetsk (as of the summer of 2017). In this regard, the retailer is inferior to both Svyaznoy and Euroset.
  • Lack of postal delivery. If there are no DNS stores in your city, then you will not be able to buy the thing that interests you.
  • Not the most big number payment methods. Only Yandex.Money is accepted from electronic means of payment, and even then with some restrictions.
  • A strangely implemented bonus system. Bonus points are rewarded with very rare goods, which makes the raison d'être discount card is lost.

If there are DNS stores in your city, then we recommend buying smartphones there. Here you will be satisfied with prices, assortment, and ease of ordering.

But the article will focus on the DNS company. So what is DNS and what makes this firm special? We can say that this is a kind of retail chain with a federal scale.
