Question

The term one gigabyte refers to:

• A. $1024$ petabytes
• B. $1024$ megabytes
• C. $1024$ kilobytes
• D. $1024$ bytes

Answer 1

We know that:

1. $\text{1 KB=$2^{10}$ Bytes=1024 Bytes}$
2. $\text{1 MB=$2^{20}$ Bytes=$(1024)^2$ Bytes}$
3. $\text{1 GB=$2^{30}$ Bytes =$(1024)^3$Bytes}$

$\therefore$ $1$ GB $=2^{30}$ Bytes $\implies 2^{10}*2^{20}$ Bytes$\implies1024$ MB

Option $(B)$ is correct.

Answer 2

1GB=1024Mega Bytes=1024*1024 Kilo Bytes=1024*1024*1024 Bytes

option 2) is the correct answer
