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.

This small device allows wireless peripherals such as keyboards and mice to communicate with the computer. It is usually plugged into the computer's USB port and acts as a bridge between the computer and the wireless device.

USB-C is the latest version of the USB interface that brings many improvements, including faster data transfer speeds, a smaller and reversible connector design, and the ability to deliver higher power for charging devices.

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.

Anti-ghosting is a feature of keyboards that allows multiple simultaneous keystrokes to be recorded flawlessly. This feature is essential for gamers and professional users who require fast and accurate inputs, for example for using complex keyboard shortcuts. "Ghosting" occurs when multiple keys are pressed simultaneously and the keyboard is unable to correctly record each press, which can lead to incorrect or unrecorded input. Anti-ghosting keyboards are designed to prevent this problem. They use advanced circuit designs or individual diodes for each key, this ensures that every keystroke is correctly and reliably registered no matter how many keys are pressed simultaneously.
