How many bytes are equal to $1$ kilo byte in Binary system?

This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
$1024$ Bytes

Bytes in 1 Kilobyte (Binary System)

In the binary system used commonly in computing, prefixes like 'kilo' often represent powers of 2, not powers of 10.

Therefore, 1 kilobyte (KB) is defined based on powers of 2.

  • The prefix 'kilo' in this context means $2^{10}$.
  • 1 byte is the base unit.

Calculation

To find the number of bytes in 1 kilobyte, we calculate $2^{10}$:

$1 \text{ Kilobyte (KB)} = 2^{10} \text{ Bytes}$

Calculating the value:

$2^{10} = 1024$

So, 1 kilobyte is equal to 1024 bytes in the binary system.
