"Taskmasters" Natural Recordings by Native Speakers
A person in control of or directing matters at the workplace, especially in a somewhat oppressive or tyrannical manner; a taskmaster.
The taskbar is a horizontal bar located along the bottom of a computer screen in a user interface for an operating system, typically Windows. It displays icons representing open applications and documents, the system tray (such as the clock and settings), and other features. The taskbar also provides buttons for navigating between and switching between open applications.
