Facebook is an American for-profit corporation and online social media and social networking service based in United States. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg along with fellow Harvard College students and roommates, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes.
Facebook may be accessed by a large range of desktops, laptops, tablet computers and smartphones over the internet and mobile networks. After registering to use the site, users can create a user profile indicating their name, occupation, schools attended and so on. Users can add other users as "friends", exchange messages, post status updates and digital photos, share digital videos and links, use various apps, and receive notifications when others update their profiles or make posts.
The like button is a social networking feature, allowing users to express their appreciation of content such as status updates, comments, photos, and advertisements.
Facebook enables users to choose their own privacy settings and choose who can see specific parts of their profile. The website is free to its users and generates revenue from advertising, such as banner ads. Facebook requires a user's name and profile picture (if applicable) to be accessible by everyone. Users can control who sees other information they have shared, as well as who can find them in searches, through their privacy settings.
The Library's FB started in April 2008 as an alternative means of communication with our users. We could inform our users about the library's programmes and services faster, provide links to new and existing print and online resources, and update the university community about any new developments. 'Followers' can engage with the library by commenting on posts and sharing them with their friends.
