Spinner / Loader
also known as Loader, Loading spinner, Activity indicator, Throbber
A spinner is an animated indeterminate indicator, usually a rotating circle, that tells users the system is working without estimating how long it will take. It suits short waits of roughly two to ten seconds. Because it gives no progress detail, it is poor for long operations.
