Mouse
The mouse is a peripheral that is known as a pointing device. It lets you point to objects on the screen, click on them, and move them.
There are two main types of mice: optical and mechanical. The opticalmouse uses an electronic eye to detect movement and is easier to clean. The mechanical mouse uses a rolling ball to detect movement. Generally, a mechanical mouse is less expensive, although it may require regular cleaning to keep it working properly.
Traditionally, a mouse connects to the computer using a USB or PS/2connection. However, you can also buy a wireless mouse, which can reduce clutter on your desktop.

Mouse alternatives
There are other devices that can do the same thing as a mouse but that have a different look and feel. Many people find them to be easier to use, and they also require less desk space than a mouse. The most common mouse alternatives include:
- Trackball: A trackball has a ball on top that can rotate freely. Instead of moving the device like a mouse, you can roll the ball with your fingers to move the pointer. Some mobile devices have miniature trackballs that can be controlled with your thumb.
- Touchpad: A touchpad—also called a trackpad—is a touch-sensitive pad that lets you control the pointer by making a drawing motion with your finger. Touchpads are common on laptop computers.
