READING: THE COMPUTER MOUSE
Task 5. The computer mouse described in Task 5 is an example of one of the earliest types of a mechanical mouse. The mousepad is used commonly in with mechanical mice, because in order to roll smoothly, the ball requires more friction than common desk surfaces usually provide. Below is another image of a mechanical mouse with the top cover removed.
Most mice on the market today use a USB connector to attach to your computer.
Some older mice, many of which are still in use today, have a PS/2 type connector.
This is a wireless mouse made for notebook computers. Wireless mice do not require the use of a mousepad, unless the desk has transparent or reflective surface, which creates problems for the optical or laser tracking. Most wireless mice use radio frequency (RF) technology to communicate information to your computer.
The optical mouse uses a tiny camera to take thousands of pictures every second. Most optical mice use a small, red light-emitting diode (LED) that bounces light off that surface onto a sensor. A recent innovation are laser-based optical mice that detect more surface details compared to LED technology. This results in the ability to use a laser-based optical mouse on even more surfaces than an LED mouse.
