International audienceThe academic world today welcomes a generation of students who grew up with internet. They use this tool everyday for any kind of use, finding information, sharing or communication distraction. On the one hand, social networks, they are among the most commonly used applications and they occupy about 2 hours time per day for 15-24 and about 8 hours per week for 18-35.
