FLOPS (or flops or flop/s) is an acronym meaning FLoating point Operations Per Second.
Hz (or hertz) is a measure of frequency per unit of time, or the number of cycles per second.
Flow (or packet flow)[flows per hour] is a sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain.
