Klaviatuuride

Klaviatuuride, also known as keyboards, are input devices used to enter data into computers and other electronic devices. They consist of a set of buttons, each of which corresponds to a character, function, or command. The most common type of keyboard is the QWERTY layout, which was designed to prevent jamming in mechanical typewriters. Other layouts include AZERTY, used in many European countries, and Dvorak, designed to improve typing efficiency.

Keyboards can be wired or wireless, and they can be connected to devices via USB, Bluetooth, or other wireless technologies. Some keyboards also feature additional keys for multimedia controls, such as volume up/down, play/pause, and mute. Ergonomic keyboards are designed to reduce strain on the hands and wrists, making them suitable for long-term use.

The design of keyboards has evolved over time, with modern keyboards often featuring backlit keys for better visibility in low-light conditions. Some keyboards also include touch-sensitive surfaces or additional sensors for more advanced input methods, such as gesture recognition. The development of keyboards continues to be driven by advancements in technology, aiming to improve usability, efficiency, and user experience.
