The taskbar is an element of an operating system located at the bottom of the screen. It allows you to locate and launch programs through Start and the Start menu, or view any program that's currently open. On the right side of the taskbar is the Notification Area that allows you to check the date and time, items running in the background. The taskbar first introduced with Microsoft Windows 95 and is found in all subsequent versions of Windows.
Users more familiar with Apple Macintosh computers can think of the taskbar as the Dock.
