How does octal number system work?
Octal refers to the base-8 numbering system. It comes from the Latin word for eight. The octal numbering system uses the numerals 0-1-2-3-4-5-6-7. In computing environments, it is commonly used as a shorter representation of binary numbers by grouping binary digits into threes.
What is octal number system draw table for it?
Octal numbers therefore have a range of just “8” digits, (0, 1, 2, 3, 4, 5, 6, 7) making them a Base-8 numbering system and therefore, q is equal to “8”….Octal Numbers.
| Decimal Number | 3-bit Binary Number | Octal Number |
|---|---|---|
| 5 | 101 | 5 |
| 6 | 110 | 6 |
| 7 | 111 | 7 |
| 8 | 001 000 | 10 (1+0) |
What is octal number system with example?
A number system which has its base as ‘eight’ is called an Octal number system. It uses numbers from 0 to 7. Let us take an example, to understand the concept. As we said, any number with base 8 is an octal number like 248, 1098, 558, etc.
Where is octal system used?
The Octal Number system is widely used in computer application sectors and digital numbering systems. The computing systems use 16-bit, 32-bit or 64-bit word which is further divided into 8-bits words. The octal number is also used in the aviation sector in the form of a code.
What is octal number system in computer class 7?
OCTAL NUMBER SYSTEM: The octal number system employs a base 8. It thus requires eight symbols i.e. the decimal symbols 0, 1,2,3,4,5,6,7. Octal decimal conversions are done by multiplying with 8. HEXADECIMAL SYSTEM: Sixteen symbols used in hexadecimal system are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F; hence base is 16.

What is an octal integer?
Octal, also known as “base-8,” is a number system that uses eight digits (0 – 7) to represent any integer. Octal values are sometimes used to represent data in computer science since bytes contain eight bits. For example, the octal value “10” can represent 8 bits or 1 byte.

There are four main types of number systems:
- Binary number system (Base – 2)
- Octal number system (Base – 8)
- Decimal number system (Base – 10)
- Hexadecimal number system (Base – 16)
