Thanks to this, people were able to exchange information throughout the planet, regardless of boundaries and distances. Global information resources are in a state of constant systematization, that is, humanity is constantly looking for the best ways to store and search for the necessary information. To do this on the Internet there are a large number of search engines, specialized or General purpose.

To view information on the Internet you need to have at least one program, which is called a browser. Among the most common browsers should be noted such as:
Opera — is a commercial program, more convenient and secure compared to Internet Explorer. If you stop downloading a file in advance, Opera, unlike Internet Explorer, allows you to continue downloading.

In the typical elements of each window in the operating system ( the title of the window with the control buttons, the menu bar, the toolbar) in the browser interface, an address bar or a field for entering the address of the page is added. Very typical is the toolbar buttons return to the previous page, stop loading and the like.
- Menu bar — one of the most common commands is to save the page on the local computer, change the encoding (if the text is not readable),
- Toolbar – the most used commands to return to the previous page, stop loading the page.
- Address line — this is where you enter the address of the desired page.
- Button to go to the typed address — you can not use, and press enter on the keyboard.

- Status bar — when you hover over a link, an address appears here, which, with some experience, allows you to understand where the link leads (another site, the same site, another place on the same page).
What you need to do to access Internet resources?
In order to access Internet resources, you need to know its network address. Since the Internet is constantly being updated and developed, it can not be a single directory, as I do not have a single world phone book. At the same time, there are various information retrieval systems on the Internet to help users find the information they need. Examples of such search engines may be:
- Thematic catalogue;
- Metasearch machines;
- Specialized search services.
All search mechanisms largely repeat the methods and approaches that are used in the library business. Thematic catalogue
If you need General information from a global topic or some of its areas, it is advisable to use the search thematic directories.
Subject directories — it information and reference systems, which are created manually by the editors on the basis of the information collected on the Internet server. They have a tree structure. All branches of human activity are divided into groups: science, technology, arts, Economics, politics, sports, etc., and those, in turn, – into divisions
For example, art is literature, theater, painting, music, architecture. Next is a more detailed classification. Thus, the theatrical art includes Opera, ballet, drama, musical, etc.. There are no uniform classification standards in the Internet thematic catalogues, as in the library business.
Catalogs are organized by theme and typically contain a hyperlink to return to the top level of the catalog website, rather than to individual pages within that website. Directory users begin their search by selecting a common theme from the relevant topic category, and then step by step narrow their search.
