In a Computer, a byte and a nibble generally consists of:

Correct option is D

In computing, a byte is a unit of data that typically consists of 8 bits, and a nibble is half of a byte, consisting of 4 bits. Bytes are the fundamental building blocks of data in computers, used for representing characters, numbers, or other forms of data.
Important Key Points:
1. Byte - A byte is made up of 8 bits and is commonly used to represent a single character in text (e.g., the letter 'A').
2. Nibble - A nibble consists of 4 bits, which is half the size of a byte.
3. Bit - The smallest unit of data in a computer, representing either a 0 or a 1.
4. Data Representation - A combination of nibbles and bytes is used to form larger data units, such as kilobytes (KB), megabytes (MB), etc.
Knowledge Booster:
• Option (a): "8 bits and 16 bits respectively" - This is incorrect; a byte is always 8 bits, and a nibble is 4 bits, not 16.
• Option (b): "4 bits and 16 bits respectively" - This is incorrect; it mistakenly reverses the definitions of nibble and byte.
• Option (c): "16 bits and 4 bits respectively" - This is incorrect; a byte is 8 bits and not 16 bits.
