A key characteristic of video memory is that it is embedded on a video card. This is significant because video memory, also known as VRAM (Video Random Access Memory), is specifically designed to store image data that the computer's graphics processing unit (GPU) needs to render graphics, such as textures for games and video playback. By being integrated into the video card, it allows for faster access and performance when processing visual information, leading to improved graphics rendering and frame rates in applications involving graphics-intensive tasks.

Other options, while relating to different forms of memory or storage, do not accurately describe the primary function or nature of video memory. For example, non-volatile storage refers to memory that retains information even when the power is off, which is not how video memory operates. Similarly, enhancing audio output and being used for temporary web storage are not functions associated with video memory. Instead, these concepts pertain to other areas of computing and memory usage.
