Can someone tell me the difference between "vychislitel'naia tekhnika"
and "informatika"? Is the former term older than the latter? Do they
bothh mean "computer science"? What do students use to refer to
computer science as a subject of study, either in the U.S. or in Russia?
Is one used more than the other? "Informatika" is in Marder's
Supplementary Russian-English Dictionary, by the way. Thanks!
