What is the difference between a Taskbar and a Toolbar?
Your taskbar is the long gray bar that sits at the bottom of your screen (you can move it to the top or either side of your screen though). It has the Start button, system tray, and possibly more on it. In addition, it’s where your programs buttons sit. Here’s a snapshot (reduced size):
On the other hand, Toolbars are the little strips at the top of a program that holds icons. Normally, they’re under all the menus.
Note that most programs let you customize these to your liking. You can turn certain ones on or off. In fact, many programs let you decide which buttons to display. Try double-clicking or right-clicking a toolbar and see if it supports any customization.
