A social network is a  a social structure made up of a set of actors (such as individuals or organizations) and the dyadic ties between these actors (such as relationships, connections, or interactions). A social network perspective is employed to model the structure of a social group, how this structure influences other variables, or how structures change over time. The study of these structures uses methods in social network analysis to identify influential nodes, local and global structures, and network dynamics. Social networks are distinct from information, biological, or electrical networks, but theories and methods generalizing to all of these complex network are studied in the field of network science.

Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistic, and graph theory. Jacob Moreno is credited with developing the first sociograms in the 1930s to study interpersonal relationships as structures in which people were points and the relationships between them were drawn as connecting lines. These approaches were mathematically formalized in the 1950s and theories and methods of social networks became pervasive in the social and behavioral sciences by the 1980s.

The founder of Facebook

Nowadays, the popular social networking is Facebook and Twitter. By these social site, they will search their old friends and at the same time they will get the new friends. People can find friends in the whole world. I would like to share some information about Facebook with you all.
 Facebook was created by Mark Zuckerberg. It is a social networking website that was originally designed for college students, but is now open to anyone 13 years of age or older. Facebook users can create and customize their own profiles with photos, videos, and information about themselves. Friends can browse the profiles of other friends and write messages on their pages.Each Facebook profile has a "wall," where friends can post comments. Since the wall is viewable by all the user's friends, wall postings are basically a public conversation. Therefore, it is usually best not to write personal messages on your friends' walls. Instead, you can send a person a private message, which will show up in his or her private Inbox, similar to an e-mail message.


Scenario: The Malaysian Artist really love use  twitter as a place to express their feeling and also communicate with their fans. Sometimes what they post in their twitter might cause others feel unsatisfied with their words. There also happens the argument between them. If social network does not exist, do you think where they will express their feeling and what the wickedness of it?
