How many areas is the computer taskbar divided into?

It is mainly composed of start menu, quick start bar, application area and tray area. Most of the installed software can be opened from the start menu, and the shortcuts of the most commonly used programs are stored in the quick launch bar. The application area is one of the main areas when we multitask, while the tray area vividly displays the important information of computer software and hardware through various small icons, and the clock in the tray area is always with us.
