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.
