A visit corresponds with a single user session in your app or website. It can include many pageviews or events. For web, a visit ends after 30 minutes of inactivity from the user. For iOS, a visit ends after your app has entered the background.
Also, 4 server-side events constitute a single visit. Server-side events are counted differently because they aren't associated with any visits.
