From bits to yottabytes. How much data is that? | Computerworld Blogs

  • 1 Bit = one binary digit (represented by a 0 or a 1).


    1 Byte = 8 Bits (or one text character)


    1 Kilobyte = 1,000 Bytes


    1 Megabyte = 1,000 Kilobytes


    1 Gigabyte = 1,000 Megabytes


    1 Terabyte = 1,000 Gigabytes


    1 Petabyte = 1,000 Terabytes


    1 Exabyte = 1,000 Petabytes


    1 Zettabyte = 1,000 Exabytes


    1 Yottabyte = 1,000 Zettabytes (a 1 followed by 24 zeros -- 1,000,000,000,000,000,000,000,000)
