How do I set the privacy on facebook?

[S M ARIF]

The "Sharing on Facebook" section of the Privacy Settings page lets you control who can see content you share on Facebook. You can choose a master setting for this set of information from the following options: Everyone, Friends of Friends, Friends Only, or Recommended. Or, you can choose to customize each setting individually — just click "Customize settings" to do this.

If you decide to customize your settings, you’ll see a more detailed "Things I share" section. This section includes individual settings for information you’ve shared about yourself, such as your birthday, religious and political views, Places you check in to, and posts you’ve made.
