TASK BAR: A taskbar is an element of a graphical user interface which has various purposes. It typically shows which programs or applications are running on the device, as well as provide links orshortcuts to other programs or places, such as a start menu, notification area, and clock. The specific design and layout of the taskbar varies between individual operating systems, but generally assumes the form of a long strip along one edge of the screen. On this strip are various icons which correspond to the windows open within a program. Clicking these icons allow the user to easily switch between programs or windows, with the currently active program or window usually appearing differently from the rest. In more recent versions of operating systems, users can also "pin" programs or files so that they can be accessed quickly, often with a single click. Due to its prominence on the screen, the taskbar usually also has a notification area, which uses interactive icons to display real-time information about the state of the computer system and some of the programs active on it
