Wireless keyboards are portable input devices that enable computer users to type and interact with their computers without being physically tethered by a wired connection. They utilize wireless technology such as Bluetooth or radio frequency (RF) to communicate with the computer, providing greater flexibility and convenience for users. These keyboards are often compact and lightweight, making them ideal for travel and use in tight spaces. They come in various designs, including full-sized keyboards with numeric keypads and smaller, more ergonomic models that prioritize comfort and reduce strain on the user's hands and wrists. Some wireless keyboards also include additional features such as programmable keys, media controls, and backlighting for use in low-light conditions. Overall, wireless keyboards offer a convenient and versatile alternative to traditional wired keyboards, enhancing the computing experience for users in both personal and professional settings.
