powers of 10 and never powers of 2. These units are often used in a manner inconsistent with the IEC standard. Kilobit per second (symbol kbit/s or kb/s
unitsof information are also used to measure information contained in messages and the entropy of random variables. The most commonly used unitsof data
in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s =
higher speeds of 1,200 and 2,400 bit/s for asynchronous dial connections, 4,800 bit/s for synchronous leased line connections and 35 kbit/s for synchronous
