According to research from UCLA, teenage brains' reward circuits were more active when teenager's photos were liked by more peers. This has both positive and negative features. Teenagers and young adults befriend people online whom they don't know well. This opens the possibility of a child being influenced by people who engage in risk-taking behavior. When children have several hundred online connections there is no way for parents to know who they are.[107]

There are lots of social apps now, and sweetalk is a new discovery. For a long time, I have searched and tried different apps and most of the time, left disappointed and frustrated, until one day by accident, the sweetalk comes into my world. And here I would like to share with you all my feelings and experiences about this mobile app. It is probably the best free transnational social tool with the function of instant translation, supporting online translation in 30 different languages and can make me learn the foreign language easily during the chat. My English is ok, so I would like to choose to send messages to the people whom I am interested in instead of my mother tongue for the purpose of improving my English better while talking. And there are a lot of lads and gals there from all walks of life around the globe(later the screenshot will be pasted). You don’t need to pay money for the VPN service, which is really fantastic for those who are eager to make friends from abroad and learn foreign language as well without the extra trouble. Of course, you can talk with the friends from your own country and if you cannot speak English well or those you want to send messages to fail to speak English, then here comes another feature of sweetalk, that is the instant translation of sweetalk. And it is foolproof to use. All right, all of these are written during the work, a little busy now and I would end this introduction of sweetalk with some screenshots, if you like it, maybe you can give it try.
The digital divide is a measure of disparity in the level of access to technology between households, socioeconomic levels or other demographic categories.[114][115] People who are homeless, living in poverty, elderly people and those living in rural or remote communities may have little or no access to computers and the Internet; in contrast, middle class and upper-class people in urban areas have very high rates of computer and Internet access. Other models argue that within a modern information society, some individuals produce Internet content while others only consume it,[116][117] which could be a result of disparities in the education system where only some teachers integrate technology into the classroom and teach critical thinking.[118] While social media has differences among age groups, a 2010 study in the United States found no racial divide.[119] Some zero-rating programs offer subsidized data access to certain websites on low-cost plans. Critics say that this is an anti-competitive program that undermines net neutrality and creates a "walled garden"[120] for platforms like Facebook Zero. A 2015 study found that 65% of Nigerians, 61% of Indonesians, and 58% of Indians agree with the statement that "Facebook is the Internet" compared with only 5% in the US.[121]

Owned by the tech giant Alphabet (Google), this interest-based social networking platform enables you to stay in touch with people by sharing messages, photos, videos, useful links to sites and so on. It also extends support for video conferencing through Hangouts and allows businesses to promote their brands and products through Google+ business pages.
A 2014 Pew Research Center survey found that 91% of Americans "agree" or "strongly agree" that people have lost control over how personal information is collected and used by all kinds of entities. Some 80% of social media users said they were concerned about advertisers and businesses accessing the data they share on social media platforms, and 64% said the government should do more to regulate advertisers.[185]
Excessive use of digital technology, like social media, by adolescents can cause disruptions in their physical and mental health, in sleeping patterns, their weight and levels of exercise and notably in their academic performance. Research has continued to demonstrate that long hours spent on mobile devices have shown a positive relationship with an increase in teenagers' BMI and a lack of physical activity. Moreover, excessive internet usage has been linked to lower grades compared to users who don't spend an excessive amount of time online, even with a control over age, gender, race, parent education and personal contentment factors that may affect the study.[147] In a recent study, it was found that time spent on Facebook has a strong negative relationship with overall GPA.[148] The use of multiple social media platforms is more strongly associated with depression and anxiety among young adults than time spent online. The analysis showed that people who reported using the most platforms (7 to 11) had more than three times the risk of depression and anxiety than people who used the fewest (0 to 2).[149] Social media addiction and its sub-dimensions have a high positive correlation. The more the participants are addicted to social media, the less satisfied they are with life.[150]
Users typically access social media services via web-based technologies on desktops and laptops, or download services that offer social media functionality to their mobile devices (e.g., smartphones and tablets). As users engage with these electronic services, they create highly interactive platforms through which individuals, communities, and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online.
