Question

\(01\) Petabyte \((PB)\) is equal to:

• A. \(2^{40}\) Bytes
• B. \(2^{50}\) Bytes
• C. \(2^{30}\) Bytes
• D. \(2^{45}\) Bytes

Hint:

Memory units in binary: KB \(2^{10}\), MB \(2^{20}\), GB \(2^{30}\), TB \(2^{40}\), PB \(2^{50}\).

Answer 1

The Correct Option is B

In computer memory measurement, storage units increase in powers of \(2\). We know: \[ 1\text{ KB}=2^{10}\text{ Bytes}. \] \[ 1\text{ MB}=2^{20}\text{ Bytes}. \] \[ 1\text{ GB}=2^{30}\text{ Bytes}. \] \[ 1\text{ TB}=2^{40}\text{ Bytes}. \] After terabyte comes petabyte. Therefore: \[ 1\text{ PB}=2^{50}\text{ Bytes}. \] So, \(01\) petabyte is equal to: \[ 2^{50}\text{ Bytes}. \]
