From Byte, KB, MB, GB, TB to PB, EB, ZB, YB

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB?

Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese character requires two bytes of storage space, ordinary English words need about 10 bytes.

From the byte start to the top by the thousand-digit progression, namely kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB),

Petabyte (PB), Exabyte (EB), Zettabyte (ZB), Yottabyte (YB). 1KB is 1024 bytes, or 2 of

10 times, about 10 of 3 times, 1YB is already 2 80 times, about 10 of the 24 bytes, completely written down is

1208925819614629174706176.
