Chapter 2, Problem 25E

Program Plan Intro

Base 8:

• Base 8 generally represents the octal number system.
• It consists of eight digits that is from 0 to 7.
• A machine code consists of normally binary digits which are represented in bits and are very large to handle in an operating system.
• An octal digit can be obtained from a binary digit by grouping three consecutive bits starting from the right.
• Octal number is the method which represents 8 as the base of each digit.

Base 16:

• It generally represents the hexadecimal number system.
• These are widely used by computer programmers and designers.
• It consists of sixteen digits that is from 0 to 9 and from 10 to 15 and is represented with letters A to F.
• The machine code generally consists of binary digits which are represented in bits that is very difficult to handle in an operating system.
• A group of four binary digits can be referred to as a hexadecimal digit.
• Hexadecimal number is the method which represents 16 as the base of each digit.
