Redesigned site

Today was the redesigned site. This time I experimented in terms of layout layers, affordable tag div. It gives the user?The previous design was based on a table that vyyavela some flaws code. I reviewed the traffic to the site and found that most users visits the site using a web browser Internet Explorer 6-8 versions. But the duration of stay of users was low, I decided to find out: "Why is this happening?" I went to the site with IE 7 and what I see? The whole design is literally "cut" into smaller components.Spraviochnikah looked and found that IE does not see some of the parameters that are responsible for stealth table borders. Had to learn to view this familiar technology div-layout sites. This design, I tested three more common browsers: Opera 10.63, Internet Explorer 7 and Google Chrome at 1024x768. Inaccuracies and errors in design I personally do not see, but the site is not directed at me, and the user. So, time will tell - brings a similar structure of the site useful or nothing will change.Please visit Elstav - electrical work.

You can find the required cable size

Today, 1 November 2010 on the site happened next update of the material.Now you can use the site as a reference for determining the required cable cross-sections, as well as to determine the allowable long-term current wiring.

Change of site design

Today was made a complete change of site design. Changed its structure.Now the site has appeared easy navigation between chapters and articles. Background image makes it clear that the site is devoted to construction.Simultaneously with the change of design had added some price lists for electrical and installation of local area networks.

LAN Architecture

Any computer network is difficult to imagine themselves without the use of computers and transmitting information environment. In these articles, the term computer is replaced by a computer - electronic computer. 

By transmitting information to include communication channels, which can be wired or wireless.

To a wired communication channels can be attributed to connect computers using copper conductors - twisted pair - and optical, conducting data transmission over fiber optic conductors.These channels of communication technology use Ethernet. 

For wireless, or as they are called - radio channels communication protocols include the use of Wi-Fi, Bluetooth, GPRS. 

Regardless of what channels are used, computers must have their address on the network, which is assigned the address IP (Internet Protocol - Internet Protocol), which will be discussed in a special article. 

Local network is characterized by such parameters as the network topology - a scheme to connect devices transfer information network. To distinguish several topologies LAN: 

tire; 

ring; 

Star; 

grill etc. 

Each topology has its advantages and disadvantages. Now the most common topology is a star, because the creation of such a topology requires the least additional funds and it does not depend on the performance of individual computer networks. Article "star topology" is devoted to a detailed description of the above topology. 

So to summarize - in order to build a local area network LAN, you must have at least two computers, and if their number exceeds two computers, you must have the device, transmitting the information, and of course their own channels of communication, which will be data . 

Under Local Area Networks

Local area network

The site was added to the section Local Area Network LAN. 

Abbreviation: LAN stands for local area network, which in translation from English and means a local area network. In many sources we can see that one statement follows after another. 

The question arises: "If there is a local area network, then there is global?" Answer: "Absolutely, there is global!". Local networks operate in a certain area, for example, building the organization and to connect to the computers of other organizations already must resort to a global network - to such a network is the Internet. The nuances of the global WAN network shall not tell, but let's talk about the LAN in detail in the articles section. 

You may ask - what has the construction of LAN to electrical work. The fact that the specificity of laying the channels of communication for LAN, namely the use of wired communication channels is no different from the laying of cables for wiring. Yes, plus the entire website devoted to the work that we can produce - those for which we have licensed, and we believe that the employer the right to know the whole list of services we provide, whether electrical work, or work associated with setting up a network computer network equipment customers. 

Full information about the section Local Area Network.

Today, after sitting not a lot of time, I did created a site map - well, that information was not a lot, so singular headache was not. But at the same time added an article about the installation of sockets and switches. Also, read the section Sitemap.

Changes on the site

I go again produced some work on the site - added button "Contact" - are now interested, it will be easier to contact us.That's how it It looks 

Information from site

The site is gradually publish articles devoted to the description of services provided by electric fitters. This need is due to the fact that many consumers of such services simply do not know what they want, and negligent builders and others who provide services are inexperience of consumers. This infringes on the rights, agree. Therefore, on the site I posted price list for electrical work that will allow consumers to read the description of the types of work and get acquainted with the pricing.
