Internet has become an important element part of life which cannot be ignored (Khan, 2006) . The developments of science and technology have brought significant changes for human society. Thanks to the Internet, people now can up-to-date new information and connect with other people in other country without travelling. While the Internet is an era of explosive growth, new forms of communication have increasingly attracted large audiences. Internet users – especially young people, began to search for a place to satisfy every demand for information, entertainment, and connection. As a result, the social network was born which responded almost perfectly the needs. In 1997, the first social network site was introduced through the website named “Sixdegree.com” (Boys & Elliion, 2007). In these days, there are a great number of different social networking sites including: Facebook, Twitter or Instagram. It is undeniable that Social Networking had brought numerous benefits for computer users. However, it also has some drawbacks. People tend to spend more than usual time on social networking sites to update news, seek for entertainment and chat with friends. It leads to an addiction to the youth when they prefer logging and surfing sites instead of concentrating on their study and work. Therefore, this paper aims to provide an overview of Social Network and present both the positive and negative impacts of using Social Network on the Youth.

2.1. Literature Review of Social Network
Until now, there has been no exact definition of Social Network. However, according to Boyd & Ellison in 2007, social networks are web-based services that allow users to build a public or semi-public within a system; articulate a user list with shared relationships; and observe the list of relationships of those persons with other people within the system. As it was the first website in the world in 1997, SixDegrees.com allows users to create their own profile, make online-friend and communicate with the other and it attracted millions of users. Unfortunately, the website disappeared in 2001 because of their lack of complexity. These networks were very simple to use and even too simple. Users of SixDegrees could only invite and accept friend requests from their contacts (SKEMA Business School, 2010). Following this invention, numbers of social networking websites have been created. Along with the increasingly popularity, social network sites were advance with new and special features.
According to statistics by Search Engine Journal in 2014, 72% of Internet users were currently active on social networks, 71% of users access the Internet from mobile devices. The proportion of social network users aged 18-29 reached 89%, while the age group 30-49 was only 72%; 60% of people aged 50-60 were active on social networks, while those over 65 were just 43%. Moreover, according to Appota ‘s report in 2017, Vietnam had 38 million social network users and 94% used mobile to social network daily
