A bar is a piece longer than it is thick; the counter of a business; the raw metal roll; the iron lever that is used to move something heavy; a graphic sign used in writing; the fans of a team or an athlete; or the group of friends who meet frequently.
A task, on the other hand, is a work or work that must be done in a limited time or the duty that someone who is pursuing an educational program has to complete, either in an institute or through private lessons.
According to DigoPaul, the concept of task bar, like the notion of tool bar, refers to a component of the graphical interface of a software. This is a row that appears at the bottom or top of the desktop of an operating system and allows you to control various applications.
The Windows operating system, for example, presents its taskbar at the bottom of the screen. From left to right, it displays access to the Start menu, a quick launch bar, taskbar buttons and a space known as the notification area where the system is responsible for presenting various messages of various importance to the user.
Throughout the many versions of Windows we have seen numerous changes in the taskbar features. In Windows XP, multiple windows can be grouped under one button on the taskbar. Windows Vista, meanwhile, offers a preview of the windows.
One of the functions offered by the taskbar is to automatically hide itself when the user is not using it, so that other applications can take advantage of its space; only when the cursor is placed on the border of the screen in which the bar is hidden, it is shown again. This was especially useful in the era of small monitors, before the wave of high definition and flat panel displays, since these days it is rare that someone needs those few pixels.
More than one operating system gives us the possibility of anchoring programs to the taskbar; In short, and thinking about older concepts, it is nothing more than creating a shortcut in the bar, but done in a much faster and easier way. In general, it is enough to launch the desired application and then press the right button of the mouse on its icon in the bar, to indicate to the system that we want it to remain there once closed.
It is worth mentioning that it is possible to reverse this action at any time, simply by clicking the right mouse button on the icon that we previously created, and selecting the appropriate option to unpin the program from the taskbar. On the other hand, we can also change the place icons, simply dragging them individually to the position that suits us best, in order to achieve an organization that speeds up our work.
The taskbar is, in principle, a space that helps us organize our shortcuts to programs, find a large number of functions in an agile and dynamic way and, why not? Always have the date at hand and the time. However, depending on the operating system, it is also possible to modify its appearance to suit our tastes: the degree of transparency of its background, the size of its buttons and the combination of colors are just some of the most common options.
It should be noted that, beyond the popularity of Windows, other operating systems such as Linux or Mac OS X also have a task bar to facilitate the management of resources for users.
