A wireless keyboard is a type of keyboard that connects to a computer or other devices without the use of physical cables. Instead, it uses technologies like Bluetooth or radio frequency to communicate wirelessly. This allows for greater flexibility and mobility, making it easier to use the keyboard from a distance. Wireless keyboards often come with a battery or rechargeable option, eliminating the need for power cords. They are compatible with various devices, including laptops, tablets, and smart TVs. Many models also feature additional functions, such as multimedia controls and backlighting, enhancing user experience.
