Driver glossary

Confused by a driver format, certification label, or setup file? Look up standard terminology used in Windows device management.

About this glossary

Entries explain labels found in Device Manager, Windows Update, firmware screens, and release notes. Each definition describes what a term means, where it appears, and which layer of a computer it belongs to.

Acronyms can describe a file format, hardware interface, Windows protection, or recovery feature. The detailed pages provide that context and explain boundaries such as the distinction between software capability and physical hardware capability.

Concept groups

Identification: hardware, vendor, device, and setup-file identifiers explain how Windows associates a physical component with a compatible package.

Graphics: display recovery, driver models, video memory, graphics interfaces, and certification describe different parts of the rendering stack.

Platform: firmware, storage interfaces, disk arrays, and secure startup determine what hardware Windows can discover and trust.
