The graphic tool bar that appears at the bottom of the Windows screen is called a task bar. This is a feature that was first introduced with Windows 95.
The "Task Bar" is the place (the thick bar at the bottom of the screen by default) where like "buttons" are arranged all tasks which are running at the moment. There are many tasks running in the background which aren't displayed here. Those tasks are system tasks which can be found in "Task Manager" (right click on the clock and select "Task Manager"). On Task Bar will be displayed the major tasks opened by user as "Windows Explorer", "Mozilla Firefox", "Search Results", "Winamp" and many more.
