Double-clicking a mouse selects an item and executes the default action, usually "open".
Under Control Panel, look for the Mouse under Hardware. You can adjust the double click speed to suit your mouse finger.
First of all, you are the one who double clicks your mouse. If you are talking about why the mouse makes two clicking sounds when you click it once, that is because it makes one click sound when you depress the mouse button, and it makes another when you lift it up again.

The left click
Pressing the mousepad with two fingers at a time will right-click, not double click. Double clicking on an Apple computer (whether with a mousepad, or mouse) is the same as any other computer. You just double click.

Click drag means moving your pointer over an icon and then clicking on it. Then, without unclicking, moving the mouse to where you want to drop the icon. And then unclick. Double click means moving you pointer over an icon and quickly push the left mouse click button two times. Right click just means clicking the right mouse click button. This might be referring to right clicking on an icon. In which case you should hover the mouse pointer over the icon and then push the right mouse button.
A single click on an Apple Macintosh computer consists of one up and down motion on a mouse. A double-click would consist of two consecutive single clicks with no or very little time between the clicks. (It is important to note that the speed of the "double-click" can be adjusted as long as a mouse is connected to the computer.) Also, usually, a single click selects an object or icon. A double-click usually opens or launches an application or document. (This is the case when your computer is in the "Finder." You can tell you are in the "Finder" when you see the word next to the Apple icon in top left corner of your monitor/screen.) All this can become confusing due to some "directions" telling the user to "click and hold." The "click and hold" means to move the mouse arrow over the object, click down on the mouse but do not finish "clicking" by letting go for the up motion of a full click, it is essentially a "half-click." This action usually causes the mouse arrow to "grab" or "hold" the object or icon.
