Hardware Information
Hardware tools report what the web platform exposes: geometry, logical CPU count, approximate memory buckets, GPU renderer strings when available, battery on supporting engines, and screen or display capability hints.
Start with Device Information for a hub overview (including optional camera device details after permission). Open CPU, RAM, GPU, Battery, Screen, or Display Information when one signal needs a sharper note.
These pages are browser capability readouts, not OEM serial inventories. Use OS tools when a ticket needs marketing model names or exact RAM sticks.
