While originally designed for general computer input, there are several keyboard and mouse peripherals available which are designed specifically for gaming, often with gaming-specific functions built-in. Examples include peripherals by Razer, the "Zboard" range of keyboards and Logitech's 'G' series. The numeric keypad found on the keyboard is also used as a game controller and can be found on a number of separate devices, most notably early consoles, usually attached to a joystick or a paddle.
