USBnäppäimistöt

USBnäppäimistöt are computer keyboards that connect to a computer via the Universal Serial Bus (USB) interface. This has become the standard connection method for most modern keyboards, replacing older technologies like PS/2. USB offers a plug-and-play experience, meaning that typically no special drivers are needed for the keyboard to function immediately upon connection to a powered USB port.

These keyboards come in a wide variety of designs and functionalities. Standard keyboards feature a QWERTY layout with alphanumeric keys, a numeric keypad, and function keys. Ergonomic designs aim to provide a more comfortable typing experience, often with split key layouts or curved profiles. Gaming keyboards are a popular subcategory, often including features such as programmable macro keys, customizable backlighting, and faster response times. Wireless USB keyboards offer the convenience of freedom from cables, usually connecting via a small USB dongle that receives signals from the keyboard.

The USB interface provides power to the keyboard, eliminating the need for separate power adapters in most cases. Data transfer rates are more than sufficient for keyboard input, ensuring responsive typing. The versatility of USB has made USBnäppäimistöt compatible with a vast range of devices, including desktop computers, laptops, and even some tablets and smart TVs.
