A keyboard layout refers to the arrangement of keys on a keyboard, which determines how letters, numbers, and symbols are organized. The most common layout is the QWERTY layout, named after the first six letters in the top row. Different layouts exist for various languages and purposes, such as AZERTY for French or Dvorak for efficiency. Keyboard layouts can affect typing speed and comfort. Users may choose a layout based on their language needs or personal preferences. Some layouts are designed to reduce finger movement, potentially increasing typing efficiency and reducing strain during long typing sessions.
