A collection of 4 bits is known as

Correct answer: a collection of 4 bits is called a nibble.

• Definition: A nibble is a group of 4 bits.

• Why the other terms are incorrect:

• BYTE — A byte equals 8 bits, so it does not match a 4-bit group.

• WORD — The size of a word depends on the computer architecture (commonly 16 bits or 32 bits), not specifically 4 bits.

• K.BYTE — A kilobyte represents about 1024 bytes (or 1000 bytes in decimal), which is far larger than 4 bits.

• Mnemonic: 4 bits -> nibble; 8 bits -> byte.
