A video editor installs a new high-end graphics card in her computer to speed up video rendering. After installation, the computer detects the card physically. Still, video editing software cannot use its advanced features until it installs an additional component that allows the operating system and applications to communicate properly with the hardware. What does she need to install? 

A device driver is a specialized piece of software that acts as a translator between the computer's operating system (and application software) and the physical hardware component.

When a new high-end graphics card (GPU) is plugged into the motherboard, the system might recognize that something is physically connected. However, without the proper manufacturer-provided device driver (such as those from NVIDIA or AMD), the operating system doesn't know how to access the card's specific architecture, advanced rendering cores, or video memory capabilities. Installing the driver unlocks the card's full potential for video editing software.

Why the other options are incorrect:

A, B, and C are made-up, professional-sounding phrases designed to look plausible, but they do not exist as standard system components or software categories in computer hardware.
