Web and browsers

What is the Web?

The web is a term that encompasses all the websites you visit via a browser.
  • To access a website, you need to enter its address (also called URL), of the form https://nsi.rocks.
  • It is not necessary to write the https:// part because the browser adds it automatically.
  • In the browser's address bar, you can write a URL to access a website directly, or write a search to trigger the search engine.

to do

  • in a browser's address bar, write nsi.rocks to access the site directly
  • in a browser's address bar, write nsi rocks (without the dot) to access a search based on the words "nsi rocks". You should find the site in the first results.

Hyperlinks

A hyperlink (or hypertext link) allows access, from one document, to another document or to another part of the document. A hyperlink allows access to different types of resources, mainly media or websites/web pages. We will talk about this in more detail later.

In Markdown, you can easily create a hyperlink. For example, the following link: NSI Rocks is created in Markdown with the code:

[NSI Rocks](https://nsi.rocks)

Personal data

We noticed in class that during navigation, users are often asked if they want to allow cookies. We also distinguished sites that require creating a personal account, and those for which it is not necessary.

Social networks have thus been identified as websites (or applications) that allow users without accounts to view some posts, without being able to interact with them, and that require users to create an account when they want to enjoy all the features related to the platform. The most observed features are:

  • creating a post (message, status, photo, video)
  • interacting with a post (comment, reaction)
  • connecting with other accounts (subscription, following)

We identified a link between personal accounts and the existence of private data such as postal address, email address, payment-related information, and others. Thanks to the CNIL website, we learned about the existence of the concept of personal data.

The CNIL stands for National Commission for Information Technology and Civil Liberties. It is an independent French administrative authority.
It is responsible for ensuring that information technology serves the citizen and does not infringe on human identity, human rights, privacy, or individual or public freedoms.

We distinguish two categories of personal data:
