The Intel(R) LNL AVStream Camera Windows driver is a software package that allows the operating system to interact with a camera device that uses Intel's LNL (which stands for Lakefield platform) architecture. This architecture is part of Intel's 10th-generation mobile processors, specifically the Intel Core "Lakefield" series. These processors use a hybrid architecture combining high-performance cores and low-power cores, often found in ultrabooks, tablets, and other thin, compact devices.

The AVStream part of the name refers to Audio/Video Streaming, which indicates that the driver manages the streaming of video and audio data from the camera to the system. This is useful for applications like video conferencing, streaming, recording, or any software that uses a webcam.
