Computer Mice

Most computer mice connect to your computer through a USB port though some older computer mice connect to the CPU via a PS/2 cable. There are various types of Computer mice that are functional in the computer world today; one of these is the optical computer mouse which was developed by Agilent Technologies in 1999. This optical mouse uses a tiny camera built within it to take numerous pictures every second. An advantage of the optical mouse is that it can be used on almost any surface without a mouse pad. It uses a small red light emitting diode which bounces the light off that surface onto a complimentary metal-oxide semiconductor. A new invention in recent times is the laser based optical mouse which can be used on many more surfaces.

These optical computer mice are often considered better than ordinary track ball mice because they do not have any moving parts and are less susceptible to wear and tear and failure. Also they don’t trap dirt like track ball mice and thus dirt doesn’t hamper the sensors that are located within the mouse. Optical mice also do not require a special surface of a mouse pad for their smooth operation.

Another new invention in the world of computer mice is the advent of wireless computer mice. Generally it is believed that corded computer mice perform better than wireless computer mice but this is changing because of the constant improvements in world of wireless computer mice. These wireless computer mice use radio frequency technology to communicate information to your computer. Thus these mice consist of two important components one of which is a transmitter which is housed in the mouse and a receiver which is connected to the computer. Radio frequencies do not require a clear line of sight between the transmitter and the receiver so a signal from a wireless mouse can pass through barriers like your desk or monitor to your computer easily. One of the most common radio frequency technologies that computer mice use nowadays is Bluetooth.
