Wireless connectivity is an innovative technology that allows devices to communicate without cables with a computer or other devices. They can be powered by a classic battery (AA or AAA type) with long life, or by an integrated battery for practicality, but with less life. Battery life can also be further reduced by the presence of a backlight. The standard range of such a connection is 10 metres, but some devices can communicate over longer distances. This makes them ideal for laptops and for carrying around.

Bluetooth is a wireless technology designed to transfer data between devices over a relatively short distance. It is particularly popular for connecting headphones, mice, keyboards and other peripherals to computers, mobile phones or tablets.

Membrane keyboards work on the principle of a flexible membrane that is located under the keys. When the user presses a key, the membrane touches the bottom perimeter, registering the keystroke. This type of keyboard is usually quiet in use, so it is suitable for office environments. Due to their design, membrane keyboards are also more resistant to dust and spills. The membrane underneath the keys provides a degree of protection against the ingress of foreign particles and liquids, which can help prevent damage.

Optical mice use LED light and a sensor to detect motion on the surface. They are popular for their reliability and high accuracy in common applications. They work well on surfaces where light reflects well, meaning if you have a shiny or rough surface, it's better to use a mouse pad. Compared to laser mice, they can have a lower DPI resolution.

Mice are usually equipped with clickable buttons that can create noise. A quiet mouse is specifically designed to minimise this clicking noise, making it ideal for quiet workplaces, common areas or homes.

The classic mouse wheel is normally located in the middle between the two main buttons and allows you to scroll vertically through documents or web pages. This is a common and accepted feature on most mice.
