MB, English abbreviation, a storage unit in computers, the full name is MByte.
MB (full name MByte): A storage unit in computers, pronounced as "mega".
The data units MB and Mb (note the capitalization of the B letter) 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 has the same translation as the "bit" in Mbit, both are bits and are units of data measurement, but they are completely different. Byte is the "number of bytes" and bit is the "number of bits". In the computer, every eight bits is one byte, that is, 1Byte=8bit, which is a 1:8 correspondence. Therefore, when writing units, be sure to pay attention to the capitalization and meaning of the letter B. Network transmission is to transfer data stored in one place to another place. The transmission speed is the amount of data transferred divided by the standard interval of time, which is 1 second here, so 1MB/s when downloading 1024Kb/s The difference between MB and Mb: Generally, the transmission rate of modem and network communication is in "bps". Uppercase B stands for Byte, and lowercase b stands for bit. Such as 14.4Kbps, 28.8Kbps, 56Kbps, 1.5Mbps and 10Mbps, etc. Taking 1M broadband as an example, 1Mbps is equivalent to 1 X 1024/8, which is equivalent to 128 KB/s, but the above speed is only the theoretical maximum speed. Because in actual applications, about 30% of network losses such as Ethernet header, TCP header, and ATM header have to be subtracted, the maximum speed is about 87 KB/sec.
