How did it all start?

The earliest documented idea of ​​a network thatwould unite computers around the world, was born in 1962. However, the first website was launched only after almost 30 years - on August 6, 1991. It was a page created by Tim Berners-Lee, dedicated to the conception of the World Wide Web, invented by him two years earlier. The site was owned by CERN (European Organization for Nuclear Research), which is the world's largest center for high-energy physics research. Unfortunately, the very first version of the page is now unavailable. But by entering the first website in the browser's search box, you can get to its 1992 version, which gives a good idea of ​​where the history of websites began. Some content elements are clickable, but mostly navigation is done by typing commands from the keyboard.

Where is the website physically located?

It is clear that the Internet is a worldwide network, butthis does not mean that the information in it is in the air or in the wires. All web pages are located on certain servers, which are a network of powerful computers that store information about websites. This means that they all have a certain geographic location. For example, if the site server is in Moscow, and electricity is disconnected in this area, then the site will be unavailable from anywhere in the world. The place for placing web pages is sold and maintained in working order by the hosting provider. If the site is very large, then it can be on several servers, geographically located in different places.

Everything in its place

The volume of information on the Internet is growing fromawesome pace, how to ensure order in this chaos? The answer is simple - everything should have its own specific place, for which you need a unique website address. What it is? This is a combination of letters (Latin or Cyrillic alphabet) and numbers, which we enter in 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 protocol information transfer;
  • www. - at the dawn of the Internet, all sites started with this famous abbreviation, but now it is used only as a tribute to the habit: you can open the desired page, that by entering this prefix, that without it;
  • The site name is a unique name thatpurchased from a registrar. It consists of two parts separated by a dot. For example, fb. Is the name itself, and ru is the domain name in which it is located, in this case it is the domain of Russia.

Always nice and tidy

Sometimes we perceive as a fact that one andthe same site looks the same on the screen of a personal computer, that on a tablet or smartphone. And discontentedly frowning when, when changing the resolution of the monitor, the columns "run into" each other, the pictures close the text, and so on.

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

Today, a huge number of differentdevices, and creating a separate version of the site for everyone would be difficult and expensive. But thanks to the technology of "rubber" mesh layout and the capabilities of modern programming languages, this task can be automated.
