Question

One megabyte is equivalent to

• A. \(2^{20}\) bytes
• B. \(2^{10}\) bytes
• C. \(2^{30}\) bytes
• D. \(2^{16}\) bytes

Hint:

1 MB = \(2^{20}\) bytes in binary system.

Answer 1

The Correct Option is A

Concept: Memory units in digital systems are based on powers of 2.

Step 1: Basic units \[ 1\ \text{KB} = 2^{10}\ \text{bytes} \]

Step 2: Next level \[ 1\ \text{MB} = 1024\ \text{KB} \]

Step 3: Substitute \[ 1\ \text{MB} = 2^{10} \times 2^{10} \]

Step 4: Simplify \[ = 2^{20}\ \text{bytes} \]

Step 5: Conclusion \[ \boxed{2^{20}\ \text{bytes}} \]

Final Answer: \[ \boxed{(A)} \]
