The HP 724720-211 is a USB keyboard with a Hungarian layout, intended for everyday text entry and computer control. Its part number identifies the Hungary-specific version in HP’s parts listing.
The USB connection distinguishes it from the similarly numbered PS/2 keyboard. The regional suffix also matters: HP lists separate part numbers for other keyboard layouts, so this model is specifically the Hungarian variant.
It is a straightforward choice when replacing a keyboard with this exact part number or equipping a workstation for Hungarian-language typing.
