Answer» Correct Answer - Option 4 : Half byte
The correct answer is Half Byte. - Nibble is also known as half-byte or tetrade and has sixteen possible values represented by a hex digit.
- It is used to state the memory consumption to store a digit in packed decimal format within an IBM mainframe to enhance the computation and the process of debugging.
Unit Conversion Table: - 4 bit = 1 Nibble
- 8 bit = 1 byte
- 1 KB (kilobyte) = 1024 byte
- 1 MB (megabyte) = 1024 KB
- 1 GB (gigabyte) = 1024 MB
- 1 TB (terabyte) = 1024 GB
- 1 PB (petabyte) = 1024 TB
- 1 XB (Exabyte) = 1024 PB
- 1 ZB (zettabyte) = 1024 XB
- 1 YB (yottabyte) = 1024 ZB
- Decimal value of 10 in 8-bit byte system = 00001010 = 0 × 20 + 1 × 21 + 0 × 22 + 1 × 23 + 0 × 24 + 0 × 25 + 0 × 26 + 0 × 27 = 2 + 8 = 10
- Decimal value of 10 in 4-bit nibble system = 1010
- In data communication, Nibble is known as Quadbits.
- The smallest unit of information which can be stored is called as Bit.
- A single bit can only hold 1 or 0.
