How many bytes in a gigabyte is it 1 000 000 000?

Answer 1

yes, it is approx one billion bytes or exactly 1,073,741,824 bytes

Answer 2

There are three slightly different definitions of the size of a gigabyte in use:

* 1,000,000,000 bytes or 10^9 bytes is the decimal definition used in telecommunications (such as network speeds) and most computer storage manufacturers (such as hard disks and flash drives). This usage is compatible with SI. HP claims media makers Maxtor, Iomega and Western Digital adhere to using this amount.[1]
* 1,073,741,824 bytes, equal to 1024^3, or 2^30 bytes. This is the definition used for computer memory sizes, and most often used in computer engineering, computer science, and most aspects of computer operating systems. The IEC recommends that this unit should instead be called a gibibyte (abbreviated GiB), as it conflicts with SI units used for bus speeds and the like. HP states Microsoft normally adheres to this definition [1]
* 1,024,000,000 bytes, is the definition used by Hard Disk maker Seagate.

Answer 3

There are
8 bits in a byte (b)
1024 bytes in a kilobyte (KB)
1024 KB in a megabyte (MB)
1024 MB in a gigabyte (GB)
So there are 1024 x 1024 x 1024 (= 1073741824) bytes in a gigabyte.

Michael, from GB - that's Great Britain, not gigabyte :-)

Answer 4

That depends if you are a hard drive manufacturer or not. Hard drive manufacturers use 1,000,000,000 bytes per Gigabyte, everybody else uses 1024x1024x1024 = 1,073,741,824 bytes per Gigabyte.

This means your brand new 160Gb drive is really ony 137Gb, Bastards!

Answer 5

there are 2^30 bytes

Answer 6

in the word "gigabyte" only one "byte" is included. but in reality

1 gigabyte = 1 073 741 824 bytes

Answer 7

yes, it's around 1 billion bytes

Answer 8

no there are 1024MB bytes in a gigabyte (GB), 1024KB in a Megabyte (MB)...

Answer 9

1024000000 bytes

Answer 10

well there are 1024 bytes =kilobyte x 1,000,000=Megabyte x 1,000,000=Gigibyte=102,400,000,000,000,000

This amount really bytes!!!!!
