The LEN L27i-28 is likely a model of a laptop, desktop, or peripheral device (such as a printer or webcam) made by Lenovo, though I couldn't find specific information on a "LEN L27i-28" as a common product name in my knowledge base. Assuming it refers to a Lenovo device, the "Windows driver" is a software component that enables the operating system to communicate with the hardware (such as graphics, audio, network, or other peripheral devices) of the Lenovo product.
