The impact of social network in our lives In our fast-growing society, social networks take more and more space in our daily lives. Facebook, Youtube, Whatsapp are certainly the most popular of them, rare are people who have never heard of it. These networks impose today as tools of communication and sharing. They offer a lot of benefits but just as much inconvenience. Indeed, we can take a lot of benefits to be connected to social networks. First and foremost, they are great means of communication. They allow us to stay in touch and chat with our friends or family, wherever they are in the world, as long as they have internet access. They are also useful for professionals who, for example, are using Facebook more and more as a showcase for advertising (promoting their products or services) or recruiting staff. These networks can also be considered as relational tools by offering us the opportunity to develop new relationships. However, the paradox is that loneliness has never been as present in our society as before. In fact, we communicate more and more with others, but we become more and more isolated from others. In wanting to be more connected to them , we are less and less. Also one of the disadvantages of networks is its time-consuming nature. Indeed, without even realizing it, we spend a lot of time per day on the networks (chat, watch videos, check notifications, read news). In addition, these activities multi-tasking and the feeling of being constantly solicited lead to difficulties of concentration and stress. Another disadvantage, not least, is the excesses and lack of security and reliability, as illustrated by the recent case where facebook has been accused of selling personal information about its users to a communications company. We can also talk about more serious things such as cybercrime or harassment very present on the networks. To conclude, social networks makes life easier for us on the one hand, but on the other hand because of certain flaws and bad management can bring us bad surprises.
