Knowing Palettes

Hello,
Want to know what are palettes in photoshop??
Palettes are areas where features or settings for tools are found. This is where you can fine-tune the functions of the tools.The palettes are located under the Window menu. They include history, actions, navigator, information, color, swatches, styles, paths, channels,layers etc. As shown in the figures.

The default layout that is displayed when you first open Photoshop displays 11 out of the 12 avalible palettes in four floating windows.Each one has its own tab.

We can arrange and reposition the avalible palettes either individually or in groups. The floating palette system incorporated into Photoshop allows you to drag each palette away from the existing cluster to create a seprate window for that palette. The reverse is also true.We can cluster individual palette tabs into groups of our own preference.
