Generic USB Wireless Mouse Hp

A cordless mouse, also called a wireless mouse, is a mousethat connects to a computer without the use of wires. Instead, the mouse uses some manner of wireless technology, like Bluetooth, RF, or infrared radio waves. Usually, a USB receiver is plugged into the computer and receives signals from the cordless mouse.

Note: Cordless mice needs batteries to work. Typically they use AA batteries, AAA batteries, or rechargeable NiMH or Li-ion batteries. A cordless mouse that is rechargeable requires a base station to charge the batteries in the mouse.

Most wireless mice use radiofrequency (RF) technology to communicate information to your computer. Being radio-based, RF devices require two main components: a transmitter and a receiver. Here’s how it works:

The transmitter is housed in the mouse. It sends an electromagnetic (radio) signal that encodes the information about the mouse’s movements and the buttons you click.

The receiver, which is connected to your computer, accepts the signal, decodes it and passes it on to the mouse driver software and your computer’s operating system.

The receiver can be a separate device that plugs into your computer, a special card that you place in an expansion slot, or a built-in component.

Many electronic devices use radio frequencies to communicate. Examples include cellular phones, wireless networks, and garage door openers. To communicate without conflicts, different types of devices have been assigned different frequencies. Newer cell phones use a frequency of 900 megahertz, garage door openers operate at a frequency of 40 megahertz, and 802.11b/g wireless networks operate at 2.4 gigahertz. Megahertz (MHz) means “one million cycles per second,” so “900 megahertz” means that there are 900 million electromagnetic waves per second. Gigahertz (GHz) means “one billion cycles per second.” To learn more about RF and frequencies.

Note: It’s plug and play. once the USB is connected to your system and the mouse is turned on u can start using it. There is no battery.
