Facebook is a global social networking website that is operated and privately owned by Facebook, Inc. Users can add friends and send them messages, and update their personal profiles to notify friends about themselves. Additionally, users can join networks organized by city, workplace, school, and region. The website's name stems from the colloquial name of books given at the start of the academic year by university administrations with the intention of helping students get to know each other better.Users can join and create up to 200 groups according to their interests or areas of expertise. It will appear in the search results of Facebook if the group is on public. Users can choose fan pages according to their interests to connect and interact with other strangers. Users can set their profiles on private so as to prevent acquaintances from contacting them. Users can also set their profiles on public.This allows close friends to send messages and add the user as a friend. It lets users update their personal profiles to notify their close friends about themselves. They can also join networks organized by city, workplace, school, and region to connect and interact with their close friends.Public profiles also allow any stranger or acquaintance to contact the user which results in lack of privacy. Public profiles can be blocked by any user but private profiles cannot.
The website is free to users and generates revenue from advertising including banner ads.Users can create profiles including photos and lists of personal interests, exchange private or public messages, and join groups of friends. By default, the viewing of detailed profile data is restricted to users from the same network and "reasonable community limitations".
The media often compare Facebook to MySpace, but one significant difference between the two websites is the level of customization.MySpace allows users to decorate their profiles using HTML and Cascading Style Sheets (CSS), while Facebook only allows plain text.One of the most popular applications on Facebook is the Photos application, where users can upload albums and photos.Facebook allows users to upload an unlimited number of photos, compared with other image hosting services such as Photobucket and Flickr, which apply limits to the number of photos that a user is allowed to upload. In the past, all users were limited to 60 photos per album. However, some users report that they are able to create albums with a new limit of 200 photos.Another feature of the Photos applications is the ability to "tag", or label users in a photo. For instance, if a photo contains a user's friend, then the user can tag the friend in the photo. This sends a notification to the friend that they have been tagged, and provides them a link to see the photo.
