How many bytes are in a gigabyte -?

Answer 1

There are a billion bytes in one gigabyte.

A gigabyte is a unit of computer data measurement. There are two definitions of gigabyte:

Standard definition

A gigabyte (GB) is equal to 1,000 megabytes (MB), or 1,000,000,000 (109) bytes. The prefix giga- means billion, or 109.

This is the way it is used for hard drives, DVDs, other media, and by Mac OS X and Linux.

Memory manufacturer usage

The term "gigabyte" is often used as an approximation for a power of two: 230 bytes. This is more properly called a "gigabinary byte" or "gibibyte" (GiB). In this usage, it is equal to 1,024 "megabytes" or 1,073,741,824 bytes. It is common, but incorrect, to refer to this as "gigabyte".

This is commonly used by computer memory manufacturers and in Microsoft Windows.

Here is a list of bits and bytes:

• 1 bit = binary digit
• 8 bits = 1 byte
• 1000 bytes = 1 kilobyte
• 1000 kilobytes = 1 megabyte
• 1000 megabytes = 1 gigabyte
• 1000 gigabytes = 1 terabyte
• 1000 terabytes = 1 petabyte
• 1000 petabytes = 1 exabyte
• 1000 exabytes = 1 zettabyte
• 1000 zettabytes = 1 yottabyte

Answer 2

In general, the prefixes and their corresponding quantities are

kilo = 1000

Mega = 1,000,000 = 1000 x 1000

Giga = 1,000,000,000 = 1000x 1000 x 1000

In computer terminology, however, rather that being powers of 10, the prefixes are mapped to powers of 2 which come closest to those powers of 10

1 kilobyte = 1024 bytes ≈ 1000

1 Megabyte = 1024 x 1024 = 1024 kilobytes = 1,048,576 bytes ≈ 1,000,000

1 Gigabytes = 1024 x 1024 x 1024 = 1024 Megabytes = 1,073,741,824 bytes ≈ 1,000,000,000

Answer 3

1000 bytes is a megabyte. 1000 megabytes is a gigabyte. Therefore, a gigabyte is 1,000,000 bytes
