Facebook is an online social media and social networking service owned by the American company Meta Platforms. Facebook can be accessed from devices with an Internet connection, such as personal computers, tablets and smartphones.

After registering, users can create profiles that display information about themselves. They can post text, photos and multimedia, which can be shared with any other user who agrees to be their "friend" or made public through different privacy settings. Users can also communicate directly with each other through Facebook Messenger, join groups of common interest and receive notifications about the activities of their Facebook friends and the pages they follow.
