How to Use This Guide
Spec sheets can feel like a foreign language — CPUs, NVMe, VRAM, Thunderbolt. This quick-reference glossary translates the most common computer specification terms into plain English so you can read a product listing and actually understand what you're looking at.
Terms are grouped by category below. For a deeper breakdown of how these specs affect real-world performance, see what RAM, storage, and processors actually mean for everyday use. For a broader home computing resource, the Home Computing End to End guide covers everything from setup to security.

Core Spec Terms Defined
The glossary below covers the terms you're most likely to encounter when reading computer listings, spec sheets, or review articles. Each definition is written for a general audience — no prior technical knowledge assumed.
Specs Vary by Use Case
No single set of specs is right for every household. A student doing word processing needs very different hardware than someone editing 4K video at home. Use this glossary to decode what you read on spec sheets, then match those specs to what you actually plan to do with the machine. If you're weighing form factor options alongside specs, see our guide to desktops, laptops, and tablets.
Display terminology follows similar patterns across device categories. If you encounter display specs while shopping for a TV, our guide to TV panel technology explains those terms in the same plain-language style. For smartphone spec sheets specifically, see Smartphone Specs Decoded.
