It is possible to access a multitude of information and services with just a “click”, since the Internet facilitates the search of data, images, documents and visits to web pages, in just a few seconds. What is an internet server? Companies, telecommunications operators and different users, access these services daily and automatically. However, it is questionable how this information can be arrived at, or, in other words, how one can, for example, access the scanner, printer or fax connected to a computer from the office. This protocol is possible through the “Internet Server”. But, what is an Internet server? How does it work? and what types of servers are the most used?

What is an internet server

An Internet server is a computer connected to the Internet whose main functions are to store web pages usually written in HTML (HyperText Transfer Protocol), manage databases and respond to requests from web users.

This computer connected to the computer network, works by running programs with precise tasks, such as serving web pages, serving customers, etc. That is, the Internet server stores the files that make up a web page, and also contains different fragments that control the way in which users can access these files. In addition, among the main features of Internet servers are that they can be located by their IP address and can also specialize depending on their types of data sent, such as customer data, html, videos, images…

However, it is important to know how an Internet server works. Generally, a browser requests a file via HTTP every time it needs a file from an Internet server. This is known as the “HTTP request”. Thus, when the request waits for the correct Internet server, the HTTP server forwards the requested document, called “HTTP response”. In addition, the Internet server works permanently, and responds to these requests through the “network protocols”.

Also, two types of servers can be distinguished: “static” servers and “dynamic” servers. Static servers consist of a computer and an HTTP server. On the other hand, dynamic servers have other components. The first type of server, owes its name to its way of proceeding, since the server sends the files, without modifying them previously, to the browser. However, the second type, the dynamic server, updates the files before sending them to the browser via HTTP.

In addition, depending on its shape, size and operation, it should also highlight three types of servers: “tower” servers, “rack” servers and “blade” servers. The first, the tower server, owes its name to its tower or column shape and is used mostly in small businesses. The second, the rack server, has a more flattened shape, so it can be stored in any small space. In addition, the rack server contains the same elements as the first server type. Finally, the blade type server, (formed as its name indicates by small sheets), unlike the other types of servers, is the most powerful and least economical. However, it can not work alone. That is, for the blade servers to contain the power supplies and network connections, they need to be incorporated into a chassis.

Currently, there are many Internet servers used, however, among them, the WEB servers, DNS, Proxy, Apache, Nginx, IIS and Microsoft Personal Web Server stand out. An Internet server is responsible for responding to requests from Internet users through the Internet. This computing device, as its name suggests, has as its main function “serving” customers according to the “client-server” principle. Among the main services are access to web pages, email, data storage, access control, etc … Internet servers can be classified as static and dynamic, as well as according to their size and shape in tower type, rack type and sheet type.
