Hello, I’ve got an important question for you: do you know why you can read that page? No? In that case, this article is made for you!
First, you certainly know the binary numeral system; that’s with this combination of zeros and ones your computer works! One number is called a “bit” (binary digit) and a combination of 8 bits is called an “octet”. Your computer treats these bits with logic gates (not, or, and, xor) to do operations with a processor… not easy, is it? But you can’t read these numbers so you need a decoder: that is the BIOS, a Basic Input Output System. People work hard with bits to create BIOS such as Windows or Linux. Without the BIOS, you couldn’t use your computer; it’s a very important system! Softwares allow you to do anything: writing a text, surfing on the web or recording your voice, you use softwares. OpenOffice, Internet Explorer or Audacity are softwares. People who make softwares are called programmers; they write very long codes in special languages. These are called “programming languages”. To code you need to know one of them; it’s a bit like learning a new language.
What does the language do?When you write a command on your program, the language translates it on binary, which your computer can understand and execute.
There is a huge list of languages but each one has a different goal. For example, HTML (HyperText Markup Language) is a language used to code internet pages; it can be combined with a code written with CSS (Cascading Style Sheets) that is used to lay-out the pages. To make programs on the Internet, such as a game, you can use Java, PHP, Ajax, ActionScript, ...Here’s a little tip for you: to recognize which language is used to code a website: Right click on the page and click on “Afficher le code source de la page”: you can see the code that allows you to see that page. Now, in the first line of the code, there is the name of the programming language. Look, I did it with the school’s website:
The language’s name isn’t written in every website! In that case, you will only see this: <!DOCTYPE html>.
Thank you for reading!

Identité Secrète (Abduction)
I have chosen this movie because I love it. This is a movie with lots of action so the public don't get bored. In addition, the main actor Taylor is handsome. This movie tells the sad story of a child who discovers his true story, this film is touching.
Nathan Harper, a teen, does a lot of nightmares. One day, while preparing an essay on the disappearance of children with his classmate Karen, he notices on a specific site, a photo of a child, Steven Price, who looks like him. Searching into the home of his parents, he discovers that he is Steven and his parents are not his own. Upset, Nathan gets in touch with the website owner, unaware that he is a Russian agent. The young man becomes the target of the killers who murdered his adoptive parents. Gradually he discovers that his mother, Lorna Price, is dead, murdered in a hotel room. He understands that repetitive nightmares are linked with the death of his mother, because he was present at that time. He also learns that his father is a CIA agent and that he was put into a foster family to be protected, with adoptive parents and a psychologist who are in charge of his survival. He then obtains a mobile phone (from Martin, his father) including a list of 25 people who sold confidential information and state secrets. Martin had stolen the list from Mr Kozlow (a bad man), and he wants to capture Nathan to have this list back and at the same time to kill Martin.

Descriptors are at the back of the packaging. The symbols indicate the category of the game and the recommended age:3 or 7 or 12 or 16 or 18 years old.They give important information to parents to protect their children.
Finally,In my opinion it's more important to respect these pictograms if we don't want to be shocked.
