A computer having a memory capacity of 256 M Bytes can store ______ bytes at maximum.

Correct option is A

\The correct answer is (a) 256 × 1024 × 1024.

Memory size is typically measured in bytes (B), where 1 KB (kilobyte) = 1024 bytes, 1 MB (megabyte) = 1024 KB = 1024 × 1024 bytes.
If the computer has a memory capacity of 256 MB, it can store:
256 MB = 256 × 1024 × 1024 bytes.
Thus, the total memory capacity in bytes is 256 × 1024 × 1024 bytes.

Additional Information:

• 1 MB = 1024 × 1024 bytes
• 256 MB = 256 × 1024 × 1024 bytes
