In Finnish it's "tietojenkäsittelytiede" which consists of:

* "tieto": knowledge but also sometimes information or even data. Computer is "tietokone", knowledge machine (IMO "tieto" one of the worst words in Finnish due to the too broad scope which is why we also say "informaatio" and "data" these days)

* "käsittely": processing or handling

* "tiede": science
