RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)

Half a byte

A kilobyte

A gigabyte

A terabyte

The correct answer is

Half a byte

Nibble Definition in Computer Terminology

In computer science, a nibble represents a small unit of digital information.

A nibble consists of exactly 4 bits.
A standard byte is composed of 8 bits.
Comparing the two, 1 byte = 8 bits = 2 nibbles.
Thus, a nibble is equivalent to half a byte.

The question asks to identify a nibble among the given computer terminology options. Based on the definition:

Option 1: Half a byte (This aligns with the definition of a nibble = 4 bits).
Option 2: A kilobyte represents 1024 bytes.
Option 3: A gigabyte represents 1024 kilobytes.
Option 4: A terabyte represents 1024 gigabytes.

Therefore, the correct identification of a nibble is half a byte.
