MB: Do you think Barack Obama has been influenced in any way by your father?
It would be delusory to take the MB's democratic protestations at face value.
Baloney and wishful thinking aside, the MB would be calamitous for U.S. security.
Abbreviation of millibar
Abbreviation of megabit
Abbreviation of megabyte
(Or "Mb") megabytes or megabits. When referring to the size or data transfer rate of a storage device which is accessed in multiples of eight bits (e.g. RAM, hard disk) this almost certainly means megabytes, but when referring to the data transfer rate of a communications system it probably means megabits. Some years ago, it is claimed, "MB" always meant megabytes and "Mb" meant megabits but recently this useful distinction has been lost.
