Information and telecommunications network is a set of methods and technologies used to obtain the necessary information that can ensure the activities of the company, as well as satisfy the personal needs of users. It is important to understand that the qualitative characteristics of the information received, that is, its reliability, volume, relevance and other characteristics, often depend on the owner of the information product, and not on the computer network.
Information and Users
Information and telecommunications network is a set of resources that face one important problem - information content. The development of the global infrastructure makes it more and more relevant, because many subnetsand collections of data make the process of servicing each user very complicated. The use of information and telecommunication networks requires the high quality of the information that is supplied to them, as well as high-quality comprehensive user service, high-quality equipment. An important point also applies to search engines, which often do not match the capabilities declared in advertising.
Practice shows that even trained users are not able to fully evaluate the parameters of the presented systems. Quite often, those systems that have become known thanks to advertising actually turn out to be not so effective, since in these cases the main part of the efforts of manufacturers is aimed specifically at advertising promotion, and the quality problems of the supplied software 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 are high cost with wide coverage. In specialized systems, all possible information is missing, and therefore their cost is lower. It is important to understand that the number of documents included in the brochures does not always serve as a sign of completeness and advantage of the purchased system. Quite often, the full texts of documents are replaced by short library cards. If an information and telecommunications network is being created, this necessitates the involvement ofcertain funds. At the same time, a supplier of products is selected that offers: the most convenient conditions for payments, low cost, technology for updating, a warranty service system, documents that indicate the possibility of selling.
Foreign telecommunication networks
The use of information and telecommunication networks implies the existence of several different types, which became the progenitors of one single one. That is, it implies a certain evolutionary process, the result of which was the emergence of the world-famous Internet.
ARPANET - for 15 years has been the most developed global network connecting computers. At the moment, it is one of the largest subnets of the Internet. The main focus of this complex is taken on tasks related to research activities.
INTERNET
INTERNET is the largest information and telecommunication network. Its definition as global is due to the fact that it covers every corner of the globe. There are more than 30 million people here as users, and this figure is increasing every year. Here, at the moment, all services that are typical for public information and telecommunication networks are presented. The US National Science Foundation maintains and funds much of the Internet, which is focused onsolution of educational and research problems. For these purposes, several specialized subnets are presented here:
- NSFnet is characterized by a hierarchical structure and concentration around large university centers in the United States of America;
- Milnet is a network owned by the US Department of Defense;
- NASA Science Internet (NSI) - this information and telecommunications network is a collection of several computer networks engaged in space research, space physics, as well as other areas of a scientific nature, which are combined into a common global internet.
BITNET
BITNET, like the Internet, is one of the oldest global networks. It provides network access to distributed databases of a research nature. Bitnet has several regional parts:
- Central and Western Europe - EARN; this includes computers from research centers in England, France, Germany, Italy and other countries;
- Canada - NetNorth.
EVnet is the largest computer network in Europe, launched in 1982. This information and telecommunications network is an extensive structure that has regional offices in all European countries, as well as in the B altic States and Russia.
Fidonet is a youth network for informal communication.
Russian telecommunication networks
UseInformation and telecommunications networks are taking place everywhere, and in Russia they were formed on the basis of industry networks. Not so long ago, their task was the formation of databases and electronic communications to provide access to them. Therefore, these two areas of information activity on Russian territory are practically not distinguished even now. At the moment, there are three closed systems that have become the main ones: the network of the Presidential Administration, which has become an association of subjects of the Russian Federation, all bodies and ministries of legislative and executive power; network "Atlas" - a combination of the banking network and public authorities; network PIENet SIC "Kontur" FAPSI. All these networks are designed for special needs and are not available to ordinary users.
Industry networks
When the old system of economic management collapsed in the 1990s on the territory of the former USSR, many enterprises were faced with the fact that they lacked business information. It was at this time that the business in the field of information and intermediary services flourished. The collapse of the usual system gave impetus to attract financial resources and the formation of a commercial information infrastructure. It was then that many industry networks served as the basis for the formation of commercial organizations providing telecommunications services.
Basic for business development
At that moment, many firms from abroad joined the Russian market in order to create such a development tool asinformation and telecommunications network. The foreign representatives had a concept of how it should work, because many networks and subnets have been functioning quite successfully there for many years. It was then that specialized systems were formed, designed to provide access to the international level: Sprint, BizLink, Infonet, PIENet, GTS interlinc, Infotel. They were created by joint ventures based on foreign equipment and technologies. Now they have become part of the Internet information and telecommunication network.
Development of telecommunications and networks
At the moment, the development of the industry around the world is carried out at a rapid pace. If we talk about compliance with the law, then the information and telecommunication network is a technological system designed to broadcast information over communication lines. Access to information can be carried out exclusively with the use of computer technology. Data transmission via the Internet information and telecommunications network is carried out without restrictions, provided that the requirements of federal laws for the dissemination of information and the protection of intellectual property are strictly observed. At the moment, many companies, both in Russia and around the world, are engaged in the development of networks for global, federal, regional, corporate purposes, and also supply enterprises participating in networks with high-quality technological equipment manufactured in full compliance with television and television standards.ties.
