What is the bar called that appears at the topmost line of a window, displaying the name of the document or program?

The correct answer is Title Bar. The title bar is a standard graphical user interface element located at the very top of most application windows. Its primary function is to display the name of the open document or program, providing immediate context to the user.

• The Menu Bar is typically located below the title bar and contains drop-down menus (e.g., File, Edit, View) for accessing commands.
• The Status Bar is found at the bottom of a window and displays information about the current state of the program or document.
• The Tool Bar (or Ribbon in modern applications) contains buttons and icons for quick access to frequently used commands.
