Question

One-megabyte memory storage in form of bytes is equal to ___________

• A. $1024$ bytes
• B. $1024^2$ bytes
• C. $1024^3$ bytes
• D. $1024^4$ bytes

Answer 1

$1$ Megabyte $ = 2^{20}$ bytes $ = \left(2^{10}\right)^{2}$ bytes $ = 1024^{2}$ bytes.

So, the correct answer is $(B).$

Answer 2

$\because 1\:MB=2^{20}$ Bytes $=\ 2^{10} \times 2^{10}$ Bytes

$\because 1\:KB=1024$ Bytes $\implies(1024 \times 1024)$ Bytes $ =(1024)^2$ Bytes

Option $(B)$ is correct.
