How does a website work?
A web page is a set of files, generated by an html code, which we have access to through an internet connection. These files are public and anyone can access them using a browser. The browser is a program that reads the html files and displays them in a user-friendly way.


Domain : This is the name that the browser will look for to show us the website. This name translates the IP number of the address into a 'nice' name, which is memorable and identifies the service. An example is this very website you are reading: cursosfemxa.es . There are independent international organizations that guarantee the registration of website names. In Spain, the ESNIC is the entity in charge of managing .es domains.
Hosting : This is the service through which we 'host' the files that make up our website on a server (a very powerful computer specialized in providing access to websites). This access could be achieved by having a computer connected 24 hours a day, but it is more effective and cheaper to contract these services to specialized companies that have large data centers dedicated to this purpose.
HTML files : This is the set of files that browsers decipher when they access the server to show us text, images, videos, sounds, etc. and that make up web pages.


What is a search engine?
It is a website that provides a very specific service: it finds websites related to the concepts we ask for in each search.

Search engines are not a collection of russia phone data information files about a company, nor do they provide a service, for example, for viewing videos. They are based on an algorithm that is activated when we make a request and that, based on certain criteria, establishes a ranking of the best web pages referring to the keyword we have entered.

The best known is Google, and all companies want to appear in the top positions in their searches. The set of techniques that are applied to try to appear as high as possible in the ranking of Google (or other search engines) is called 'web positioning'.

Its importance is so high that many people confuse Google with the navigation program or application (the best known are Chrome, Firefox or Explorer), and instead of writing an address (domain) in the navigation bar, they do it in this search engine, so the references found can be misleading when finding a certain website.
