Information and Telecommunications Network - a set of methods and techniques used to obtain the necessary information, which is able to ensure the operation of the company, as well as to meet the personal needs of users.It is important to understand that the qualitative characteristics of the information received, that is, its accuracy, scope, relevance and other characteristics, are often dependent on the owner of the information products, and not on a computer network.
information and users
Information and Telecommunications Network - a collection of resources, before which stands up one important problem - the content.The development of the world's infrastructure makes it all the more urgent, because the set of subnets, and aggregates the data to make the process of service for each user greatly complicated.Information and telecommunications networks require high-quality information that they supplied, as well as high quality comprehensive service users, quality equipment.An important point concerns the search engines, which often do not correspond to the declared in advertising opportunities.
Experience shows that even advanced users are not able to fully assess the options presented systems.Quite often, those systems that have become known through advertising, in fact, are not so effective as in these cases, the bulk of the effort is directed at manufacturers of advertising promotion, and the quality of the delivered software problems go by the wayside.
Types of information and telecommunication networks
There are two separate classes of telecommunication networks: universal and specialized.The characteristics of universal systems is the high cost, with broad coverage.The specialized systems not all possible information, so their cost is lower.It is important to understand that the number of documents entered in the brochures are not always a sign of fullness and benefit of the acquiree.Quite often, the full texts of documents are replaced by brief library card.If you create an information-telecommunication network - it is necessary to attract certain funds.This selects the product suppliers offering: the most convenient conditions for payments, low cost technology to upgrade the service system of safeguards documents that indicate the possibility to sell.
foreign telecommunication network
Information and telecommunication networks implies the presence of several different types, which have become the progenitors of one single.That is, it implies a certain evolutionary process, which resulted in the emergence of world-famous Internet.
ARPANET - was for 15 years the most advanced global network that connects computers.At the moment it is one of the largest Internet subnets.The main landmark of the complex taken on tasks related to research activities.
INTERNET - it is the biggest information and telecommunications network.Defining it as a global due to the fact that it covers every corner of the globe.As users there are more than 30 million people, and every year this number increases.There currently presented all the services that are specific to the information and telecommunications networks.US National Science Foundation provides support and funding for most of the Internet, which is aimed at addressing educational and research objectives.For this purpose, there are a few specific subnets:
- NSFnet is characterized by a hierarchical structure and a concentration around the major university centers in the United States;
- Milnet - a network owned by the Ministry of Defense;
- NASA Science Internet (NSI) - this information and telecommunications network - a combination of several computer networks involved in space exploration, space physics, and other areas of scientific nature are united in a common global internetwork.
BITNET, as well as the internet, this is one of the oldest networks of a global nature.Here granted network access to distributed database research character.In Bitnet has several regional units:
- Central and Western Europe - EARN;here including computers research centers in England, France, Germany, Italy and other countries;
- Canada - NetNorth.
EVnet represents the largest computer network in Europe, which was launched in 1982.This information and telecommunications network - a branched structure, which has regional offices in all the countries of Europe and in the Baltic States and Russia.
Fidonet - Youth Network for informal communication.
Russian telecommunications networks
Information and telecommunication networks is happening everywhere, in Russia they were formed on the basis of sectoral networks.Not so long ago their mission was the formation of databases and electronic communications to provide access to them.Therefore, these two areas of information activities on the Russian territory and is now virtually demarcated.Currently there are three closed systems, which have become major: Network Administration of the President, which has become a union of subjects of the Russian Federation, all the ministries and agencies of the legislative and executive authorities;network "Atlas" - a set of banking network and state authorities;Network PIENet SIC "Kontur" FAPSI.All these networks are designed for specific purposes and are not available to ordinary users.
When the 90-ies of the last century on the territory of the former Soviet Union there was a disintegration of the old system of economic management, many enterprises are faced with the fact that they lacked business information.This is what accounts for the flourishing business in the field of information and mediation services.The collapse of the customary system gave an impetus to attract financial resources and the formation of a commercial nature of the information infrastructure.It was then that many branch network provided the basis for the formation of commercial organizations providing telecommunications services.
basis for business development
At the time, many companies from abroad involved in the Russian market with the aim to form a tool for development, as information and telecommunications network.The concept of how it should work, at the foreign representatives were, in fact there are already many years quite successfully operated many networks and subnets.It was then formed specialized systems, designed to provide access to the international level: Sprint, BizLink, Infonet, PIENet, GTS interlinc, Infotel.They were created by the joint venture on the basis of foreign equipment and technology.Now they have become part of the information and telecommunications on the Internet.
development of telecommunications and networks
Currently development of the industry throughout the world is carried out rapidly.If we talk about the appropriate legislation, the information and telecommunications network - a technological system designed to broadcast information via communication lines.Access to information may only be subject to the use of computer technology.Transmission of data through information and telecommunications network Internet is carried out without any restrictions provided that the requirements of federal laws to the dissemination of information and intellectual property are observed strictly.At the moment, many companies, both in Russia and around the world engaged in the development of global networks, federal, regional, corporate purpose, as well as supply companies participating networks high-quality technological equipment manufactured in full compliance with the standards of television and communication.
