An exabyte is a unit of information or computer storage equal to one quintillion bytes. It is commonly abbreviated EB When used with byte multiples, the SI prefix may indicate a power of either 1000 or 1024, so the exact number may be either: * 1,000,000,000,000,000,000 bytes - 10006, or 1018, or * 1,152,921,504,606,846,976 bytes - 10246, or 260. -Frank-Source: http://en.wikipedia.org/wiki/Exabyte
Ok then, here is the definitive answer to the question:
1,024 KB = 1 MB (Megabyte)
1,024 MB = 1 GB (Gigabyte)
1,024 GB = 1 TB (Terabyte)
1,024 TB = 1 PB (Petabyte)
1,024 PB = 1 EB (Exabyte)
1,024 EB = 1 ZB (Zettabyte)
1,024 ZB = 1 YB (Yottabyte) (1 with 24 zeros after it!!!)
Bear in mind, it is estimated that there is only around 160 Exabytes of information in existence...
Now that is geeky huh!
it can be measured in bytes, kilobytes, megabytes, gigabytes, terabytes, exobytes, etc. also, it can be measured in bits
The current maximum size of an NTFS partition is 16 exabytes (18 billion gigabytes). Assuming you can divide up the drive into four primary partitions, you can have 64 exabytes on a hard drive. Of course, Windows still uses BIOS addressing to find the size of a hard drive, so it is still limited by what the BIOS can see. Currently, the newest BIOSes support a maximum of 144 petabytes (144 million gigabytes).
