Organizations involved in the development of the World Wide Web and the Internet in general. By category of tasks to be solved

World Wide Web around Wikipedia

The World Wide Web is made up of millions of Internet web servers located around the world. A web server is a computer program that runs on a computer connected to a network and uses the HTTP protocol to transfer data. In its simplest form, such a program receives an HTTP request for a specific resource over the network, finds the corresponding file on the local hard drive and sends it over the network to the requesting computer. More complex web servers are capable of dynamically generating documents in response to an HTTP request using templates and scripts.

To view information received from the web server, a special program is used on the client computer - web browser. The main function of a web browser is to display hypertext. The World Wide Web is inextricably linked with the concepts of hypertext and hyperlinks. Most of the information on the Internet is hypertext.

HTML (HyperText Markup Language) is traditionally used to create, store and display hypertext on the World Wide Web. The work of creating (marking up) hypertext documents is called layout, it is done by a webmaster or a separate markup specialist - a layout designer. After HTML markup, the resulting document is saved to a file, and such HTML files are the main type of resources World Wide Web. Once an HTML file is made available to a web server, it is called a “web page.” A collection of web pages makes up a website.

The hypertext of web pages contains hyperlinks. Hyperlinks help World Wide Web users easily navigate between resources (files), regardless of whether the resources are located on local computer or at remote server. To determine the location of resources on the World Wide Web, uniform resource locators URL (English Uniform Resource Locator) are used. For example, the full URL of the main page of the Russian section of Wikipedia looks like this: http://ru.wikipedia.org/wiki/Main_page. Such URL locators combine URI (Uniform Resource Identifier) identification technology and the DNS (Domain) domain name system Name System). The domain name (in this case ru.wikipedia.org) as part of the URL designates the computer (more precisely, one of its network interfaces) that executes the code of the desired web server. The URL of the current page can usually be seen in address bar browser, although many modern browsers prefer to show only the domain name of the current site by default.

Technologies

To improve the visual perception of the web, CSS technology has become widely used, which allows you to set uniform design styles for many web pages. Another innovation worth paying attention to is the resource naming system URN (Uniform Resource Name).

A popular concept for the development of the World Wide Web is the creation of the Semantic Web. The Semantic Web is an add-on to the existing World Wide Web, which is designed to make information posted on the network more understandable to computers. The Semantic Web is a concept of a network in which every resource in human language would be provided with a description that a computer can understand. The Semantic Web opens up access to clearly structured information for any application, regardless of platform and regardless of programming languages. Programs will be able to find the necessary resources themselves, process information, classify data, identify logical connections, draw conclusions and even make decisions based on these conclusions. If widely adopted and implemented wisely, the Semantic Web has the potential to spark a revolution on the Internet. To create a computer-readable description of a resource, in semantic web RDF format is used Resource Description Framework), which is based on XML syntax and uses URIs to identify resources. New products in this area are RDFS (eng. RDF Schema) and SPARQL (eng. Protocol And RDF Query Language) (pronounced "sparkle") new language requests for quick access to RDF data.

Story

This is what the very first web server designed by Tim Berners-Lee looks like

Tim Berners-Lee and, to a lesser extent, Robert Caillot are considered the inventors of the World Wide Web. Tim Berners-Lee is the originator of HTTP, URI/URL, and HTML technologies. In 1980 he worked at the European Council for Nuclear Research (French). conseil européen pour la recherche nucléaire, CERN) software consultant. It was there, in Geneva (Switzerland), that for his own needs he wrote the Enquire program (eng. Enquire, can be loosely translated as “Interrogator”), which used random associations to store data and laid the conceptual basis for the World Wide Web.

Development of information technologies

As part of the project, Berners-Lee wrote the world's first web server, called "httpd", and the world's first hypertext web browser, called "WorldWideWeb". This browser was also a WYSIWYG editor (short for what you see is what you get - what you see is what you get), its development began in October 1990, and was completed in December of the same year. The program ran in the NeXTStep environment and began to spread across the Internet in the summer of 1991.

Mike Sendall buys a NeXT cube computer at this time in order to understand what the features of its architecture are, and then gives it to Tim [Berners-Lee]. Thanks to perfection software system"NeXT cube" Tim wrote a prototype illustrating the main concepts of the project in a few months. This was an impressive result: the prototype offered users, among other things, such advanced capabilities as WYSIWYG browsing/authoring!... During one of the sessions of joint discussions of the project in the CERN cafeteria, Tim and I tried to find a “catching” name for the system being created . The only thing I insisted on was that the name should not once again be taken from the same Greek mythology. Tim suggested "world wide web". I immediately really liked everything about this name, but it’s hard to pronounce in French.

The world's first website was hosted by Berners-Lee on August 6, 1991, on the first web server, available at http://info.cern.ch/, (). The resource defined the concept “ World Wide Web", contained instructions for installing a web server, using a browser, etc. This site was also the world's first Internet directory, because Tim Berners-Lee later posted and maintained a list of links to other sites there.

The first photograph to appear on the World Wide Web was of the parody filk band Les Horribles Cernettes. Tim Berners-Lee asked the band leader for scanned photographs after the CERN hardronic festival.

But still theoretical basis The web was founded much earlier than Berners-Lee. Back in 1945, Vannaver Bush developed the concept of Memex - mechanical aids for “extending human memory”. Memex is a device in which a person stores all his books and records (and, ideally, all his knowledge that can be formal description) and which provides the necessary information with sufficient speed and flexibility. It is an extension and addition to human memory. Bush also predicted comprehensive indexing of text and multimedia resources with the ability quick search necessary information. The next significant step towards the World Wide Web was the creation of hypertext (a term coined by Ted Nelson in 1965).

Since 1994, the main work on the development of the World Wide Web has been undertaken by the World Wide Web Consortium (English: world wide web consortium, abbreviated as W3C), founded and still led by Tim Berners-Lee. This consortium is an organization that develops and implements technology standards for the Internet and the World Wide Web. W3C Mission: “Unleash the full potential of the World Wide Web by establishing protocols and principles to ensure the long-term development of the Web.” Two other major goals of the consortium are to ensure full “internationalization of the Web” and to make the Web accessible to people with disabilities.

The W3C develops uniform principles and standards for the Internet (called “recommendations”, English W3C recommendations), which are then implemented by software and hardware manufacturers. This ensures compatibility between software products and equipment from various companies, which makes the World Wide Web more advanced, universal and convenient. All recommendations of the World Wide Web consortium are open, that is, they are not protected by patents and can be implemented by anyone without any financial contributions to the consortium.

Development prospects

Currently, there are two directions in the development of the World Wide Web: the semantic web and the social web.

The Semantic Web involves improving the coherence and relevance of information on the World Wide Web through the introduction of new metadata formats.
The social web relies on users to organize the information available on the network.

In the second direction, developments that are part of the semantic web are actively used as tools (RSS and other formats, web channels, OPML, XHTML microformats). Partially semanticized sections of the Wikipedia category tree help users consciously navigate the information space, however, very soft requirements for subcategories do not give reason to hope for the expansion of such sections. In this regard, attempts to compile knowledge atlases may be of interest.

There is also a popular concept Web 2.0, which summarizes several directions of development of the World Wide Web.

Ways to actively display information

Information presented online may be available:

read-only (“passive”);
for reading and adding/changing (“active”).

To the ways active display information on the World Wide Web include:

This division is very arbitrary. So, let's say a blog or guest book can be seen as special case forum, which, in turn, is a special case of a content management system. Usually the difference is manifested in the purpose, approach and positioning of a particular product.

Some information from websites can also be accessed through speech. India has already begun testing a system that makes the text content of pages accessible even to people who cannot read and write.

Safety

Proposed solutions to relevant problems vary significantly, even to the point of completely contradicting each other. Large security solution providers like McAfee, Avira, Avast and others develop products for assessing information systems for compliance with certain requirements; other market players (for example, Finjan) recommend active research program code and generally all content in real time, regardless of the data source. There are also views that businesses should view security as a business opportunity rather than as a cost; To achieve this, the hundreds of companies providing information security today must be replaced by a small group of organizations that would enforce the infrastructure policy of constant and widespread management digital rights.

Confidentiality

Every time when user computer requests a web page from the server, the server determines and, as a rule, logs the IP address from which the request came. Likewise, most Internet browsers record information about the pages you visit, which can then be viewed in your browser history, and also cache downloaded content for possible reuse. If an encrypted HTTPS connection is not used when interacting with the server, requests and responses to them are transmitted over the Internet in clear text and can be read, written and viewed at intermediate network nodes.

When a web page requests and the user provides a certain amount of personal information, such as first and last name or real or email address, the data stream can be de-anonymized and associated with specific person. If a website uses cookies, supports user authentication, or other technologies for tracking visitor activity, then a relationship may also be established between previous and subsequent visits. Thus, an organization operating on the World Wide Web has the opportunity to create and update the profile of a specific client using its site (or sites). Such a profile may include, for example, information about leisure and entertainment preferences, consumer interests, occupation and other demographic indicators. Such profiles are of significant interest to marketers, advertising agency employees and other specialists this kind. Depending on the terms of service of specific services and local laws, such profiles may be sold or transferred to third parties without the user's knowledge.

Disclosure of information is also facilitated by social networks, which invite participants to independently disclose a certain amount of personal data about themselves. Careless handling of the capabilities of such resources can lead to information that the user would prefer to hide become publicly available; among other things, such information may become the target of hooligans or, moreover, cybercriminals. Modern social media provide their members with a fairly wide range of profile privacy settings, but these settings can be unnecessarily complex - especially for inexperienced users.

Spreading

Between 2005 and 2010, the number of web users doubled to reach two billion. According to early research in 1999, most existing websites were not indexed correctly by search engines, and the web itself was larger than expected. As of 2001, more than 550 million web documents had already been created, most of which, however, were located within the invisible network. As of 2002, more than 2 billion web pages were created, 56.4% of all Internet content was in English, followed by German (7.7%), French (5.6%) and Japanese (4. 9 %). According to studies conducted at the end of January 2005, at 75 different languages over 11.5 billion web pages have been identified and indexed on the open web. And according to data for March 2009, the number of pages increased to 25.21 billion. On July 25, 2008, Google software engineers Jesse Alpert and Nissan Hiai announced that Google's search engine had detected more than a billion unique URLs.

World Wide Web Technologies

In general, we can conclude that the World Wide Web stands at " three pillars": HTTP, HTML and URL. Although in Lately HTML started somewhat give up their positions and give them up more modern technologies markup: XML. XML eXtensible Markup Language) is positioned as a foundation for other markup languages.

The website is perceived by the user as a single whole organism; it necessarily has its own individual address.

To understand what it is - a website on the Internet, let's consider a simple analogy. Take any book. It consists of separate chapters, articles, stories and other divisions. However, they are most valuable in the aggregate, because they continue each other. Likewise, a website acts as a book that combines various materials.

Why do you need a website?

Many entrepreneurs today wonder what a website is for. When we need to buy a product or order a service, we look for what we need on the Internet. Companies that have their own websites undeniably gain a huge advantage over their competitors.

Here are just a few reasons to open a website.

Spread of information. Web site - great way convey to the audience information about your company, talk about specialization, activities, services, pricing policy etc.
Effective advertising. If a company creates a website, it automatically becomes its tool for promoting advertising.
A platform for communication. The website is also a means of communication; here both employees and clients can communicate with each other and the company. Good result allows you to obtain feedback from users.
Image formation. The website creates a positive image of your company on the Internet, increases the status of the organization, and forms a loyal attitude among consumers.
Effective marketing. The site allows you to promote and sell products/services.

Types of sites

. This is a small directory about the company, where basic information about its activities and contacts is presented in a concise, clear and concise manner on one page. The main advantages of such a resource: inexpensive and quick to create, easy to use.
. The main task of this resource- increase business profits. Using the corporate website, clients can view the catalog, place orders, learn about promotions, etc. A corporate website is proof that your business is serious and thorough. This is not the cheapest advertising tool, but if done correctly, the effect is worth it.
Promo site. Used in cases where a promotional company/competition/promotion is launched. In structure it resembles advertising brochure or prospectus, is designed brightly and juicy to be sure to attract users.
Showcase site. This is the best option for a business that sells one product/group of similar products. Here these products are described from all sides, their detailed photos, price. The catalog is organized in such a way that the user can find the desired position with a minimum number of clicks.
Online store. Here you can not only view the product, but also order it, and on some resources, pay immediately. Its main property is that it should be as simple and convenient as possible so that the user can make a purchase without any obstacles.

There is a classification of websites according to various criteria:

Purpose of creation:

Commercial (on the website you can buy goods, place an order).
Non-profit.

By access type:

Open (everyone has access).
Semi-open (certain conditions must be met to gain access).
Closed (access is available to a limited number of persons.

By category of tasks to be solved:

Multifunctional, multidisciplinary resources (cover various areas).
News (platforms for exchanging news).
Highly specialized, dedicated to a specific topic.
Forums and social networks (created for information exchange and communication).
Introductory (created to familiarize the audience with a company/product/service, etc.).
Information or article (articles and interesting publications are posted here).
Entertaining (their the main task- so that the user has a good time).
(here users can perform certain tasks).

How to create a website

There are several ways to create an online resource.

Contact the professionals

You can order the creation of a website in a web studio or from a freelancer, describe your requirements and wishes. Among the advantages of the method, the following can be noted: no specialized knowledge and skills are needed, professionals will take care of the site (there will be no errors or failures), time saving. The only negative is that you will need to spend money, and the more complex the site, the more.

Buy a ready-made resource

Advantages of the method: find the appropriate resource that suits you. you receive a ready-made resource with everything you need (content has already been written, indexing and promotion has been completed); your efforts to open a website come down to visiting a website buying and selling exchange. Cons: you waste time searching for a site, you need to have at least minimal knowledge to buy a resource that can work effectively, and again you need money.

Create it yourself on hosting with a designer

You can choose paid or free resource. Free hosting has a number of disadvantages: limited capabilities: little space on the hard drive, few scripts, minimal technical capabilities, the presence of third-party advertising on the resource, a third-level domain is provided, templates for site design are limited, the hoster is not responsible for the site. Paid resource It already has advanced functionality; you can connect a CMS to it, which works with databases and scripts. It is best to create a website on paid hosting, which has a convenient website builder. Here you need to pay a hosting fee; the designer is usually free.

How the website works

For the user, everything is extremely simple: the browser displays a set of pages that have banners, a navigation system, news, and more. However, if you look underneath outer shell, you can see all the elements written in the programming language. All visitor requests are sent to the server, where they are instantly processed and returned in finished form as a response.

For the site owner, the need is obvious constant update data, placement of new material, resource management. For this purpose, Content Management System (CMS) is used. This is an engine that allows you to create pages based on user requests and needs. Inside the CMS there are 2 interfaces: user and administrator, that is, a side for visitors and a side for the administrator. Adding content, setting up modules, mailing and other operations are performed from the administrator block. Editing is performed with a special WYSIWYG editor, which is very similar to Word.

For an administrator, it is important to have a CMS and a database management system. This is where all information and content of the resource will be stored. CMS system works in the PHP programming language.

As you can see, with proper organization and smooth operation, a website is a platform for attracting customers, effective promotion goods and services.

Every day we use the Internet, but often we don’t think about what technologies are behind the simple and easy search process necessary information and communication. Can you accurately answer the question about what types there are and why they are displayed equally, whether on a 21-inch monitor or on a 7-inch smartphone? Read on and you will find out the answers to these questions.

Definition

Websites are collections of documents known as web pages (or pages for short). They contain some information: images, text, video, audio materials and more. The main page of the website, the so-called the start file is called home, from which you can go to all other pages. They are linked by hyperlinks that are highlighted or represented using images. When you move the cursor over them, it takes on the appearance of a hand with an extended index finger. After clicking on such elements, the user is moved to a new location. This could be a different page, a different location on the same page, or a different website.

Web pages are written in a language called markup language HTML hypertext. Browsers (programs used for such as Internet Explorer, Firefox, Opera, Safari, Google Chrome etc.), read it and display the necessary information.

Where did it all start?

The earliest documented idea for a network that would connect computers around the world was born in 1962. However, the first website was launched almost 30 years later - on August 6, 1991. It was a page created by Tim Berners-Lee, dedicated to his idea two years earlier World concept Wide Web. The site belonged to CERN (European Organization for Nuclear Research), which is the world's largest center for the study of high energy physics. Unfortunately, the very first version of the page is no longer available. But after entering search bar first website browser, you can get to the 1992 version, which gives a good idea of where the history of websites began. Some content is clickable, but most navigation is accomplished by entering commands from the keyboard.

Where is the website physically located?

It is clear that the Internet is a worldwide network, but this does not mean that the information in it is in the air or in wires. All web pages are located on specific servers, which are a network of powerful computers, which store information about websites. This means that they all have a certain geographical location. For example, if the site server is located in Moscow, and there is a power outage in this area, then the site will be unavailable from anywhere in the world. Space for hosting web pages is sold and maintained by the hosting provider. If the site is very large, then it may be located on several servers, geographically located in different places.

Everything is in its place

The amount of information on the Internet is growing at an alarming rate, so how can we ensure order in this chaos? The answer is simple - everything must have its own specific place, which requires a unique website address. a combination of letters (Latin or Cyrillic) and numbers, which we enter into the appropriate line of the browser and get to the desired site. Some people are confused by the unfamiliar term "website url". What it is? It's simple, it's the same as the address. It consists of several parts:

prefix http:// - means the type of information transfer protocol;
www. - at the dawn of the Internet, all sites began with this famous abbreviation, but now it is used only as a tribute to habit: you can open the desired page, either by entering this prefix or without it;
The site name is a unique name that is purchased from the registrar company. It consists of two parts separated by a dot. For example, fb. is the name itself, and ru is the designation domain zone, in which it is located, in this case it is the Russian domain.

Classification of sites

Depending on the functions performed, there are the following types of web resources:

Information site - used to post articles and materials of a certain direction or on a general topic. This news portals, blogs, encyclopedias, etc.

A corporate website is the website of a business or organization. It can have two functions:

ensuring communication between employees of departments and branches to coordinate their activities;
about the company to potential clients. For existing buyers there may be Personal Area, in which you can track the status of purchases, discount levels, etc.

Developing such a resource is a long and labor-intensive task, so only large companies can afford them. Small businesses use business card and portfolio websites in their activities. They are made quite simply, but provide all the necessary information about the company.

Commercial websites are online stores different types: from multi-page hypermarkets to one-page sites that provide only one or a few products for ordering. Their main goal is to sell or receive an application for services.

Service websites are search engines, mail, hosting. This also includes online bulletin boards.

Always beautiful and neat

Sometimes we take it for granted that the same website looks the same whether on a personal computer screen or on a tablet or smartphone. And we frown with dissatisfaction when, when changing the monitor resolution, the columns “run into” each other, the pictures cover the text, etc.

In order to avoid these inconveniences, it was developed adaptive design websites. This means that the resource has been designed so that it looks the same on different devices. This is achieved due to the fact that when the site is loaded, it receives information about the conditions in which it will be displayed: platform, screen resolution, and orientation.

Today there are a huge number of different devices in use, and creating a separate version of the site for each would be difficult and expensive. But thanks to the technology of the "rubber" mesh layout and capabilities modern languages programming, this task can be automated.

What is website support?

This is a system of measures to ensure stable operation the site and the performance of its functions, which is carried out by the site administration or provided by third parties for a fee. It comes in the following types:

Technical - checking the functionality of the site, protection against virus attacks, timely renewal of the domain name and hosting, monitoring of work mailboxes, troubleshooting. This also includes the regular creation reserve bases data.
Informational - filling the site, creating appropriate content, updating data.
Marketing - includes work to promote the site in search engines, advertising on the Internet.
Design support - responsible for the appearance of the site, its correct display, selection or drawing of the necessary pictures.
