Social networks are social structures, which are composed of groups of people. These people are connected by relationships. In the last years, social networks have become very famous. These social networks are used to find people with common interests or to get more knowledge. These also are used to communicate with friends and family all the time.

Facebook is the social networks most used here. Now Facebook has more than 500 million legistred users around the world. The creator of this social network, probably never would thought about this situation, his name is Mark Zuckerberg and he is a programmer and U.S businessman. At the beginning, idea the network only was for university students, but it quickly expanded. For example, some services of Facebook are chatting with your friends, uploading photos or writing in you wall.

Twitter is another social network, it is a little different. This network is more used by famous people. It consist of uploading messages with a maximum of 140 characters, these messages and call tweets. If you are a twitter follower, you can follow your favourite singer or actor.

In my opinion, the subject at networks is interesting, you can communicate with everybody, but on the other hand you can observed. And there are people who don't like to feel connected with everybody all the time.
