21.What’s a social network and how do I manage what I let people find about me?

 

A social network is a website or app allowing you to connect with friends and family, and share stories, news, photos or video. Examples of different social networks include Facebook, Google+, Twitter and LinkedIn. These websites are some of the biggest on the Internet. There are more than one billion people on Facebook, YouTube gets four billion views every day, and Twitter has more than 500 million users. Most social networking sites allow you to adjust your settings – helping you manage what information you share, how you share it, and who you share it with.
