An organization that provides access to the Internet and other Internet-related services is called a provider.

– Today, a huge number of people use the global Internet. And you will certainly agree with me that the Internet has become an integral part of our lives.

Let’s find out what opportunities the global computer network Internet provides us today.

Students:

1) Search for information,

2) Download photos, videos, music and other files.

3) Communication in the network (in social networks).

4) The use of electronic libraries, museums …

5) Purchases via the Internet (Internet stores).

6) Study through the Internet.

7) Search for weather, schedules, jobs…

8) Search for programs (distributed for free).

9) Email, etc.

Question : What can be concluded?

Students: The Internet helps us and saves a lot of effort and time.

– Quite right, but you need to remember two points – firstly, about copyright for a particular file, program, video, etc., and secondly, the Internet is not only useful information, but also computer viruses .

III. Learning new material.

– Now let’s move on to the study of the topic. In the course of my story, you yourself write down the information you need.

Working in the network, you need to quickly navigate the available amount of information. And special programs help us in this, which are called … browsers .

Definition: Browser is software for browsing websites , that is, for requesting web pages (mainly from the Web), processing them, displaying them, and moving from one page to another. Presentation “Methods of searching for information”

– What browsers do you know?

1. Internet Explorer is too slow and too unstable. The only thing that keeps it afloat is that it comes pre-installed on every Windows operating system.

2. Google Chrome is one of the fastest browsers. Speed comes at the expense of many of the features found in other browsers. Too simple and too minimalistic. It should be recognized that Google Chrome is a sprinter in the world of browsers in terms of cold start and page loading.

3. Mozilla Firefox – Potentially fast, very easy to learn and surprisingly easy to set up. There are very few buttons on the toolbar (the main place is occupied by the line for entering the address and search). This browser gets used very quickly, and despite the limited basic capabilities, there is a huge scope for expansion. A lot of innovation, convenience and stable operation – these are the three pillars on which FireFox is based. Reliable browser for professionals and beginners of the Internet.

4. Opera – very fast! Very stable job. Minimalism. Opera pioneered many of the innovations that are now standard on other browsers. Excellent, innovative browser. It is simple, quite functional and has good speed and stability indicators, has a very unusual interface.

5. Yandex. Browser (versions 1.1, 1.2, 1.5) is a free browser created by Yandex in 2012, a simple and fast browser with a concise design and a serious approach to security (files uploaded by the user are checked for malware by a system created by Kaspersky Lab). A single line for addresses and search queries. Scan downloaded files for viruses. Easy transfer of settings from another browser. Turbo mode for faster page loading.

There are three ways to find information on the Internet:

1. Indication of the page address.

2. Movement on hyperlinks.

3. Access to the search engine (search server).

Let’s take a look at each of them:

1. Indication of the page address .

This is the fastest way to search, but it can only be used if you know exactly the address of the document or the site where the document is located.

2. Moving on hypertext links .

This is the least convenient method, since it can be used to search for documents that are only similar in meaning to the current document.

But this method is very simple and suitable for a novice user.

A feature of Web pages is the presence of hypertext links. A hyperlink or just a link can be a piece of text that is always a different color from the rest of the text and is usually underlined with either an icon or a picture. By pointing to a particular link, you can view the text associated with it, listen to an audio recording, view an image, video clip, go to another Web page.

Using hypertext links, you can travel indefinitely in the information space of the Web, moving from one web page to another, but given that many millions of web pages have been created in the world, it is unlikely that you will be able to find the necessary information on them in this way.

3. Access to the search engine .

Search server addresses are well known to everyone who works on the Internet. Currently, the following search servers are popular in the Russian-speaking part of the Internet: Yandex (yandex.ru), Google (google.ru) and Rambler (rambler.ru).

A search engine is a software and hardware complex with a web interface that provides the ability to search for information on the Internet.

According to the principle of operation, search engines are divided into two types: search directories and search indexes.

Search directories serve for thematic search. The information on these servers is structured by topics and subtopics. With the intention of covering a narrow topic, it is not difficult to find a list of web pages dedicated to it.

Search indexes work like alphabetical indexes. The user specifies a word or a group of words that characterize his search area, and receives a list of links to web pages containing the specified terms. Search indexes automatically, with the help of special programs (web spiders), scan Internet pages and index them, that is, they enter them into their huge database.

– So, list in what ways we can find information on the network?

And now let’s take a closer look at the most popular search engines in Russia.

The rating shows that the most popular search engine is Yandex . Yandex is a Russian web search engine. The company’s website, Yandex.ru, was launched on September 23, 1997. The head office of the company is located in Moscow. The company has offices in St. Petersburg, Yekaterinburg, Odessa and Kyiv. The word “Yandex” (consisting of the letter “I” and part of the word index; the fact that the Russian pronoun “I” corresponds to the English “I”) was coined by Ilya Segalovich, one of the founders of Yandex.

The second most popular system is Rambler . The history of the Rambler search engine begins in 1991 in the town of Pushchino, Moscow Region. It was there that a group of like-minded people created the company “Stack”. Headed the company “Stack” Sergei Lysakov. The company was engaged in local networks and Internet connection.

In third place is Google . The leader of Internet search engines, Google occupies over 70% of the world market. Now it registers about 50 million search queries daily and indexes more than 8 billion web pages. Google can find information in 115 languages. The corporation was founded in 1998 by Stanford University graduate students Larry Page and Sergey Brin According to one version, Google is a distorted spelling of the English word googol. “Googol” is a mathematical term for one followed by 100 zeros. The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and first described in Kasner and James Newman’s Mathematics and the Imagination. Google’s use of the term reflects the challenge of organizing the vast amounts of information on the Internet. The Google interface contains a rather sophisticated query language that allows you to limit your search to specific domains, languages, file types, and so on.
