Explanation
The Knowledge Lightning component is a component that allows users to access articles from the Service Cloud Console app. However, if users want to access articles from a different app that does not use the console, they can use the Knowledge related list instead. The Knowledge related list shows articles related to a record based on data categories and shows article details such as title, summary, rating, and view count. To add the Knowledge related list to a record page, an administrator can use the page layout editor and drag and drop the Knowledge related list to the appropriate section on the page layout.
