The problem asks us to find which of the given options is equivalent to 1 Gigabyte. The options are expressed in terms of MB, bits, bytes, and KB.

1. Problem Description

The problem asks us to find which of the given options is equivalent to 1 Gigabyte. The options are expressed in terms of MB, bits, bytes, and KB.

2. Solution Steps

We need to know the relationships between Gigabytes, Megabytes, Kilobytes, Bytes, and bits.

1 Kilobyte (KB) = 1024 Bytes

1 Megabyte (MB) = 1024 KB

1 Gigabyte (GB) = 1024 MB

So, 1 GB = 1024 MB. Option (1) is 1000 MB. Since 1024 is greater than 1000, option (1) is not the correct answer.

Consider Option (2): $1024 \times 1024$ bits

1 Byte = 8 bits

1 KB = 1024 bytes = $1024 \times 8$ bits

1 MB = 1024 KB = $1024 \times 1024 \times 8$ bits

1 GB = 1024 MB = $1024 \times 1024 \times 1024 \times 8$ bits

Option (2) is $1024 \times 1024$ bits which does not equal to $1024 \times 1024 \times 1024 \times 8$ bits.

Consider Option (3): $1024 \times 1024 \times 1024$ bytes

1 KB = 1024 bytes

1 MB = 1024 KB = $1024 \times 1024$ bytes

1 GB = 1024 MB = $1024 \times 1024 \times 1024$ bytes

Therefore, 1 GB = $1024 \times 1024 \times 1024$ bytes. This is the correct answer.

Consider Option (4): $1000 \times 1024$ KB

1 MB = 1024 KB

1 GB = 1024 MB = $1024 \times 1024$ KB

Since 1024 x 1024 KB is not equal to 1000 x 1024 KB, Option (4) is not correct.

3. Final Answer

(3) $1024 \times 1024 \times 1024$ bytes
