In Informatica PowerCenter (which this question appears to reference), transformations are classified into two main categories: Active transformations (which change the number of rows passing through them, like Filter or Aggregator) and Passive transformations (which don't change the row count, like Expression or Lookup). The 2 count refers to these fundamental types.
