kilobit per second (kbps)

Kilobit per second, kbit/s or kbps, is the dimension for transmission speed. One kilobit per second corresponds to a value of 10exp3 bit/s

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.

It was not until the development of local area networks (LAN) that data rates of several megabits per second (Mbit/s) were achieved, and later with 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.
