A mouse is a hand-operated electronic device that controls the coordinates of a cursor on your computer screen as you move it




Choosing the right mouse

Pick the Right Size

Most of today's mice are made for an adult size hand. If you have small hands or if you are buying a mouse for a child, smaller-sized mice are available. If you are looking for a smaller mouse, you might also want to consider notebook mice, since they are intended to be used in cramped spaces and tend to be smaller than desktop mice.

Choose a Contour

Most modern mouse designs are symmetrical, however there are some that are asymmetrical. Which mouse shape you choose depends on what feels better in your hand.

Ball, Laser, or Optical?

Back in the day ball was a standard, but today it is highly recommended that you get either a laser or optical mouse. he more dots per inch (dpi) a mouse can track, the more sensitive and accurate it is. A typical optical mouse tracks between 400dpi and 800dpi, while laser mice track more than 2,000dpi. Neither is really better; it all depends on your needs and preferences. Unless you're a gamer or a graphic artist with a need for precise movement, you'll probably find a 2,000dpi laser mouse too sensitive. Many gaming mice, however, allow you to switch sensitivity levels so that you have precision when you need it but can revert to 400dpi or 800dpi for regular mousing.

Wired or Wireless?

A wired mouse has a flexible cord that plugs into the computer; it draws its power from the computer itself and needs no batteries. A wireless mouse has no cords and transmits its information to a small receiver that plugs into the computer; wireless mice usually need two AA batteries for power.

PS/2 connection or USB 2.0 connection?

If your choosing a wired mouse its either a PS/2 or USB 2.0. Most keyboards use the PS2 connection; although more recent keyboards now offer a USB2.0 connection. There is really no difference, other then the PS2 version frees up room for the USB2.0 slot for other devices.

Mouse Pad

Mouse pads are a must if you are using a optical mouse and even if you are using a laser mouse it is still recommended.
