Facebook is a social networking website intended to connect friends, family, and business associates.
There are many social networking sites in the world Twitter, Google Plus, My space etc. But it is the largest of the other networking sites of the world. Facebook was founded in 2004 by Harvard student Mark Zuckerberg and originally called the Facebook. It began as a college networking website and was quickly successful on campus and expanded beyond Harvard into other schools.
At that time, it was only available to schools, universities, organizations, and companies within English speaking countries.
Later it was extended to include anyone and everyone. Facebook users create a profile page that includes the following: Information, Status, Friends, and Friends in Other Networks, Photos, Notes, Groups, and The Wall.
As a result, everyone within that network can view the profile. Users are able to search for friends and acquaintances by e-mail address, school, university, or just by typing in a name or location in the search box. When people become friends, they are able to see all of each other’s profiles including contact information.
A popular feature on Facebook is to share photographs uploaded from a phone, camera, or computer. A person can make a video call to any one of his friend list. Nowadays business has been largely dependent on Facebook for promotion and marketing.
But, with the advantage of Facebook, nowadays cyber criminals are committing many crimes. Above all, Facebook has become a part and parcel in the communication system.
