Data rate units

In telecommunications, data transfer rate is the average number of bits (bitrate), characters or symbols (baudrate), or blocks per unit time passing between equipment in a data transmission system. Most commonly, measurements of data transfer rate are reported in multiples of unit bits per second (bit/s) or occasionally in bytes per second (B/s). The data rates of modern residential high-speed Internet connections are most commonly expressed in multiples of bits per second, such as megabits per second (Mbit/s) or kilobits per second (kbit/s).

Standards for unit symbols and prefixes

Unit symbol

The ISQ symbols for the bit and byte are bit and B, respectively. In the context of data rate units, one byte consists of 8 bits, and is synonymous with the unit octet. The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per second), or about 0.1192 MiB/s (mebibyte per second). The Institute of Electrical and Electronics Engineers (IEEE) uses the symbol b for bit.

Mercedes-Benz S-Class

The Mercedes-Benz S-Class, formerly known as Sonderklasse (German for "special class"), is a series of flagship vehicles produced by the German automaker Mercedes-Benz, a division of German company Daimler AG. The classification was officially introduced in 1972 with the W116 S-Class, which succeeded previous Mercedes-Benz models dating to the mid-1950s. The S-Class has served as the top model for Mercedes for over fifty years in its various incarnations. The S-Class has debuted many of the company's latest innovations, including drivetrain technologies, interior features, and safety systems (such as the first seatbelt pretensioners). The S-Class has ranked as the world's best-selling luxury sedan, and its latest generation, the W222 S-Class, premiered in 2013. As in previous iterations, the W221 S-Class is sold in standard- and long-wheelbase versions; I4, V6, V8, V12, diesel and hybrid powertrains are offered. All models built in Mexico or sold in the United States are only available in long wheelbase.
