What is FTP?

FTP is a direct access service that requires a full Internet connection.

WWW (World Wide Web) – direct access service that requires a full Internet connection and allows you to interactively interact with the information provided on the web – sites. It is the most modern and convenient Internet service. It is based on the principle of hypertext and is able to present information using all possible multimedia resources: video, audio, graphics, text, etc. Interaction is carried out on the principle of client – server using hypertext transfer Protocol ( Hyper Text Transfer Protocol, HTTP). Using the HTTP Protocol, the WWW service allows you to exchange documents in hypertext markup language – Hyper Text Markup Language) format, which ensures that the content of documents is displayed properly in users ‘ browsers.

The principle of hypertext underlying WWW is that each element of an HTML document can be a reference to another document or part of it, and the document can refer to documents on the same server as well as on other Internet servers. Www links canpoint not only to documents specific to the WWW service, but also to other Internet services and information resources. Moreover, most of the programs – clients of WWW – browsers (browsers) – do not just understand such links, but also are client programs of the relevant services: FTP, network news Usenet, e-mail, etc. Thus, WWW software tools are universal for various Internet services, and the WWW information system itself performs an integrating function in relation to them.

The World Wide Web Protocol is a hypertext service for accessing remote information. Thus, the World Wide Web is one of the Internet services that offers an easy – to-use interface and enables users, even those who do not know the computer very well, to access web services in any part of the Internet.

The user accesses the WWW or FTP server directly by specifying its network address (URL)

URL (Universal Resource Locator) – unified resource pointer – is the address of the information resource on the Internet, which specifies the Protocol by the rules of which data is transmitted, the name of the server on which the file is stored, and can be specified path to the file directory and the name itself.

Access to certain Internet services depends on the location of the user, the offers of local network service providers and the user’s ability to pay for these services.

8. Information search services. A special group consists of Internet services, supported by one of the groups of its participants and ranked in this category due to the global nature of their search services. Search for information is today one of the key problems of the Internet, as the number of web – pages presented in it today is estimated at more than a few hundred million. In addition, the problems of finding information are based on such reasons as the multiplicity and fragmentation of sources, a large number of different ways of storing data, lack of time for sampling and processing information, the cost of obtaining information, unreliability of data, constant updating and addition of information.

The following are the main tools for finding information on the Internet, which can largely overcome the above problems:

– Search engines (spiders, crawlers). The main function of search engines is to study the Internet in order to collect data on existing web – sites and to provide information about web – pages that best meet the entered request. Yandex and Google search engines offer one of the best search engines Ivandex.com.ua ahhh! google.com.ua). what indexes resources in the Ukrainian Internet zone. From overseas search servers one of known – AltaVista (altavista.com).
– Catalogues. It is a hierarchically organized thematic structure in which, unlike search engines, information is entered on the initiative of users. Added page hard bound to the accepted directory categories. One of the most famous Russian catalogs list.mail.ru ahhh!
– Meta-search tools. Allow you to improve the process by running multiple search tools at the same time. This method significantly increases the speed, but does not allow you to take advantage of the capabilities of building complex queries offered by most modern search engines.
The Internet provides new opportunities for the company’s business development. Commercial organizations consider the Internet as a public information and communication resource. With the help of the Internet, firms can develop new products, take orders, receive the necessary correspondence and official documents, conduct specialized information searches in the relevant institutions.

E-mail, combined with fast interactive protocols such as TELNET and file transfer Protocol (FTP), is an effective tool for productive interaction over the Internet. FTP and TELNET provide clients with the ability to access the resources of a remote server machine from their machines in an interactive mode (on – line). Using FTP, users can connect to other computers and search their public access directories, copy to their media the information and programs they are interested in, and post their own correspondence. TELNET Protocol connects users to a remote machine and gives them access to its software resources.

With dial-up access using SLIP or RRR protocols that are at a considerable distance businessmen, scientists, government and corporate employees can exchange draft documents and comments to them and thus quickly make final decisions.

Intranet – internal local area network of the organization, which is created and operates on the basis of Internet-technologies. It is an organization of the company, which is based on a single internal information local network (Intranet). The introduction of Intranet increases the efficiency of employee interaction and optimizes the planning and management processes. The internal local Intranet networks of organizations use the same hardware and software, the same protocols and approaches as the Internet. In fact, Intranet is the Internet in miniature.

4) significant reduction in the cost of administration of software applications in user workplaces;
5) quick updating of any changes in the information store of the institution;
6) the shift of emphasis on the creation of information on its effective consumption.
External interaction of the company with partners, suppliers and customers is carried out on the basis of Extranet-networks. Extranet-two or more Intranet networks, combined for the purpose of sharing the resources of organizations; it is a set of business partners, existing on the basis of the network, which is controlled by Internet providers using TCP / IP Protocol and Web-technology.
