or 1,000 bit/s.The notation kbps is mainly used in Anglo-Saxon countries, whereas the notation kbit/s is used in Germany. Data transmission rates of several kilobits per second were state of the art in the seventies. Common data rates for terminal networks and for transmission in wide area networks
were 9.6 kbit/s and 19.2 kbit/s at that time. These data rates were still valid in the eighties.Ethernet that data transmission speeds of several gigabits per second (Gbit/s) were also achieved, and with 100 Gigabit Ethernet even those of 100 Gbit/s.
