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.
