A volcano is considered Active if it is currently erupting or expected to erupt in "the near future".

The problem is that "near future" is pretty ambiguous. If there is a fairly well defined date range for the predicted next eruption on the order of perhaps a range of a year or so (or maybe a decade or so) it would be considered active. If the best guess is on the order of a hundred or more years in the future, it would be considered dormant.

Some definitions consider any volcano that has erupted in the last 1000 years to be "active".

What does it mean if volcano is active?

you can get active, dormant (or sleeping) and inactive volcanoes. an active volcano is one that is very likely to erupt in the future and still has magma in it. a dormant (or sleeping) volcano is one that has not erupted for the past thousand-or-so years, but can still erupt an inactive volcano is highly unlikely to ever erupt again. every volcano will eventually become inactive. at one time, there were volcano in the UK, but they have all died out now (or become inactive) !!

What is the difference of an active volcano and a dormant volcano?

An active volcano is one which maintains a hot magma chamber, so that it might erupt anytime in the future. An inactive (extinct or dormant) contains mainly cooled lava and is not likely to erupt unless there is a new supply of hot magma.
