The term 'Parts of a Facebook Feed' refers to the components that make up a user's Facebook page. These components include ADS (3 letters) and Posts (5 letters). ADS are sponsored content that appears on a user's feed, usually from businesses or organizations. Posts are updates that users share with their friends and followers, such as photos, videos, and text-based updates. Both ADS and Posts appear on a user's Facebook feed, allowing them to interact with their friends and the wider world.
