MB

Mb is a unit of measurement used to quantify the amount of information contained in a message or data set. It stands for "mebibyte," which is a binary unit of digital information. One mebibyte is equal to 2^20 bytes, or 1,048,576 bytes. The term "mebibyte" is part of the International System of Quantities (ISQ), which is based on powers of 1024, as opposed to the decimal system which uses powers of 1000. This distinction is important in the context of digital storage and data transfer, where binary units are more commonly used. The prefix "mebi-" comes from the binary prefix "mebi," which is derived from the Latin word "mega," meaning "great." The use of mebibytes helps to avoid confusion between binary and decimal units, which can be particularly important in fields such as computing and telecommunications.
