The word "mb" is not a standalone word in the English language
It is most likely an abbreviation or acronym for something else. In written English, it is not appropriate to use abbreviations or acronyms that are not commonly known or easily understood by readers. Instead, it is best to spell out the full word or phrase. For example, instead of writing "I'll be there in 5 mb," it would be more appropriate to write "I'll be there in 5 minutes."

Still, the same $10 charge applies whether the limit was breached by 1 MB or a smidgen under 50 GB .The vast majority of subscribers never get close to these limits, providers say, and Babbage's back-of-the-envelope calculations accord with this claim.
Passengers still won't be able to watch streaming video, listen to internet radio, or download more than 10 MB at a time.
The genomes of Mimiviruses and Pandoraviruses, which are some of the largest known viruses, range from 1 to 2.5 Mb (1 Mb = 1,000,000 base pairs of DNA).
Per kilogram mole, χn is on the order of 10−8/T; in solid hydrogen this just exceeds the electronic diamagnetism of 1 K. Curie's law should hold when mB is much smaller than kT, provided that no other forces act on the atomic dipoles.
For example, the saturation vapour pressure at 40 °C (104 °F) is 74 mb (0.07 standard atmosphere), and the standard atmospheric pressure near 18,000 metres (59,000 feet) above sea level is also 74 mb; thus, it is where water boils at 40° C. The everyday response of relative humidity to temperature can be easily explained.
And while Freescale's production lines are already up and running, the MB-OFDM camp has yet to produce a prototype which means, says Dr Rofheart, that they are two years behind, given typical development times for wireless chips.
Martin Rofheart, the co-founder of XtremeSpectrum and now the head of Freescale's UWB operation, says a faster chip, capable of 220 megabits per second, will be ready by the end of the year, with 480-megabit and 1-gigabit chips to follow in 2005.The rival approach, backed by the MBOA, is called multiband orthogonal frequency-division multiplexing (MB-OFDM).
In 1917, with the help of several American industrialists, Martin incorporated a new Glenn L. Martin Company, which supplied its MB-1 bomber to the U.S. military.
And the multiband, frequency-hopping approach means the technology can be more easily adapted for use in different parts of the world, where regulators are likely to apply different rules to UWB.In short, DS-UWB has the advantage of being available now, while MB-OFDM is technically more elegant, but is not ready yet.
Besides, says Mr Broockman, all that elaborate signal processing makes MB-OFDM very robust in noisy environments and UWB devices, by definition, operate in noisy environments, since they have to co-exist with existing radio technologies.
