# Event (classic)

An *event* is the basic unit of information that the Engine stores about meaningful occurrences within your IT infrastructure. All objects and activities in Nexthink are linked to one or more events. When an object or activity is no longer related to any event, it is eventually removed from the system. Events are timestamped and ordered sequentially using both the clock of the Engine and the local time reported by the Collectors.

In the Finder, within the context of investigations, *events* refer only to those basic events that represent errors or warnings from devices or applications. The Device view of the Finder also displays the occurrences of these events in the **Errors** and **Warnings** timelines.
