What is the purpose of the 'Page Layout' tab in Word?

The 'Page Layout' tab in Word is specifically designed to help users adjust the overall settings of their document that affect how the content is displayed on the page. This includes functions such as setting margins, changing page orientation (portrait or landscape), and defining the size of the paper being used. These adjustments are crucial for preparing documents for printing or improving readability, making it easier to format a document to meet specific requirements.

While other tabs in Word focus on different functionalities, such as inserting visual elements or managing comments, the 'Page Layout' tab exclusively encompasses the settings that control the physical layout of the page itself and how content is organized across it. This makes it essential for ensuring that documents are both aesthetically pleasing and are formatted correctly according to the user's needs.
