Chapter 3, Problem 3P
Explanation of Solution
Octal numbering system:
- Octal number system is also known as base-8 number system
- It is because; eight distinct elements from 0 to 7 are used to represent a level.
- In order to represent a 16-bit word or a register, two digit bits are used such that each word is represented by a two digit octal number starting with “00”.
- The possible octal numbering system to represent each and every 16-bit word is given below:
