How do sites work?
The number of active Internet users is growing daily. At the same time, the number of available sites increases. But few people think about how the website works and what it is.
Below we will talk about the structures of sites, about the main types of sites and about the principles of the site on the Internet.
A website is an information resource with a specific address where it can be found on the Web. It has a well-organized structure related to its goals and objectives.
There are a number of pages that form the basis of most sites and are necessary for easy navigation:
- main or home page - contains basic information and gives a clear idea about the subject of the site; in blogs - displays the most recent posts;
- “About the site” or “About the author” - acquaints users with the goals of creating this site or with its author;
- site map - a structured list of pages and publications to facilitate the search;
- Contact Information;
- feedback form.
Each page of the site is divided into separate elements with different content:
- header - a component that is located at the top of the page and displays the name of the site, information about a brand or brand, etc .;
- navigation block - allows you to quickly navigate between pages and sections of the site. It can be displayed as a horizontal line or a vertical block;
- information field - contains the main semantic content of the page;
- site-bar - blocks, usually located on one or two sides of the main field, are intended for advertising and various widgets;
- basement or footer - includes information about developers, site counter, etc.
Types of sites
Depending on the content, the following sites are distinguished:
- business card site - a site consisting of one or several pages that contain information about a natural or legal person, indicating contact details;
- blog - a kind of online diary in which the author can share with readers his professional skills or hobbies;
- online store - a site with a catalog of goods and a set up payment system;
- corporate site - a site, as a rule, a large company with a complete description of the goods produced or services rendered.The site contains company news, promotions, vacancies, etc .;
- Portal is a major Internet resource dedicated to a specific topic. It usually provides an opportunity for users to chat on the forum, chat, set up a mailbox, etc.
By the way of displaying in the browser all sites can be divided into two types.
- Static - site pages always look the same regardless of user actions. To write them, the markup language html is used.
How websites work on the Internet
To make the site available to users, it needs to assign a domain name and place it on a special server that has enough disk space and a 24-hour high-speed Internet connection. Such a platform is called hosting, and the companies that provide it are called providers.
All computers on the web can be divided into servers and clients. How do server computers work? On the one hand, they are connected to client computers via telephone lines, leased lines or wireless networks, and on the other hand, they are connected to the Internet.With the help of special software, the provider's computer accepts requests and displays information on users' monitors.
Client computers send requests and process the received information using browser programs, for example, Internet Explorer, Mozilla Firefox, Opera and others. For the interaction of various operating systems and software, there are data exchange protocols.
All computers on the web have a unique IP address, which is a sequence of numbers, where it can be found anywhere in the world. To find a specific website on the Internet, you need to know the IP address of the computer on which it is located. To facilitate the search developed a domain name system (DNS - Domain Name System). That is, the site is assigned a symbolic name. To convert a domain address to a numeric IP address, use the DNS Server service.
Thus, for the site to work, it is necessary to assign a domain name and place it on one of the hosting sites.
