'Beendet' (ended/completed) is the past participle of the verb 'beenden' (to end/finish). It is used like an adjective and describes a state: an action or process is completed and no longer active.
Das Spiel ist beendet, die Zuschauer gehen nach Hause.
The game is over; the spectators are going home.
The word is derived from the noun 'das Ende' (the end). The prefix 'be-' forms the transitive verb 'beenden' (to end/finish), which always needs an accusative object: you always end/finish *something*.
Der Autor muss das letzte Kapitel noch beenden.
The author still has to finish the last chapter.
A common and rather formal phrase is 'etwas für beendet erklären' (to declare something ended/over). This means that a person with authority officially announces the end of something.
Der Richter erklärte die Verhandlung für beendet.
The judge declared the hearing over.

'vorbei' and 'beendet' can both express that something is no longer continuing. 'vorbei' often sounds everyday and simply describes that a period of time, an event, or a state is over. 'beendet' sounds more precise when a process has been completed or brought to an end, for example a task, a course, or a project. 'vorbei' fits well with experiences and periods of time. 'beendet' fits better when you want to emphasize the result or completion.
