What type of connection is commonly used to connect short-range wireless devices like keyboards and mice?

Bluetooth is the correct choice for connecting short-range wireless devices like keyboards and mice. This technology is specifically designed for low-power, short-range devices, typically operating within a range of about 30 feet (10 meters). Bluetooth enables seamless connections without the need for cables, making it ideal for peripherals such as keyboards and mice that benefit from mobility and ease of use.

In contrast, Wi-Fi is primarily used for connecting devices to the internet over a larger range, suitable for tasks requiring higher bandwidth and speed, such as streaming video. Infrared, while also capable of wireless communication, is generally limited to line-of-sight connections and is less common for modern peripherals compared to Bluetooth. Ethernet, on the other hand, is a wired networking standard used for high-speed internet connections and local area networks, making it unsuitable for short-range wireless connections.
