Cache
Also called: Browser cache
Stored copies of data or files that make apps and websites load faster.
Definition
A cache keeps copies of previously loaded data, such as images, scripts or API responses, so they do not have to be downloaded again. Stale caches can make testers see old versions, so clearing the cache or using a private window is a common troubleshooting step.
In practice
The developer says the logo was updated, but you still see the old one until you do a hard refresh that bypasses the browser cache.
