What does mb mean?

Mb is the name of the unit of size, the unit of mobile phone traffic is MB, and Chinese is megabyte. Data units MB and MB (note the case of letter B) are often mistaken for the same meaning. In fact, MByte means "megabyte" and Mbit means "megabit".

MByte refers to the number of bytes and Mbit refers to the number of bits. Although the "byte" in MByte is both a bit and a data measurement unit, it is completely different from the translation of "bit" in MBITE. Byte is "number of bytes", bit is "number of bits", and every eight bits in the computer are one byte, that is, 1Byte=8bit, which is the corresponding relationship of 1: 8. So when writing units, you must pay attention to the case and meaning of the letter B.
