What are the parts of a computer mouse?
The parts of a computer mouse can vary by the type of computer mouse. Below is a general overview of the parts found on most computer mice.
Buttons
Today, almost all computer mice have at least two buttons, a left button and right button for clicking and manipulating objects and text. In the past, there were mice with only one button. For example, many of the early Apple computer mice only had one button.
A desktop mouse with a wheel may have the wheel act as a third mouse button when pressed. Also, many desktop mice have additional thumb buttons, so it's also possible for a mouse to have five or more buttons.
Ball, laser, or LED
A desktop mouse uses a ball and rollers if it's a mechanical mouse or a laser or LED if it's an optical mouse. These components track the movement of the mouse on an x-axis and y-axis and move the mouse cursor on the screen. In the picture is an example of the bottom of a mechanical and optical mouse.
Mouse wheel

Instead of rolling the wheel, if you push in on the wheel, it can be used as a third button.

Other parts
If you're using a laptop, some of the above components mentioned earlier are not required. For example, a touchpad does not use a ball, laser, or LED to control movement; it uses your finger on the touchpad. Other parts include a ball for trackball mice, extra buttons on the thumb side of the mouse, and nubs used with laptop mice.
What does a laptop use for a mouse?

Also, all laptop computers can have a USB corded or wireless mouse attached to them. In the picture is an example of a touchpad found below a laptop keyboard.
