All bases that are themselves a power of two (2, 4, 8, 16, 32, etc) are useful when notating binary values because the conversion is so trivial. Normally we use base-16 (hexadecimal) because we usually work with 4-bit nybbles (half-bytes). However, sometimes we want to work with 3-bit nybbles, such as when working with 9-bit bytes, or perhaps 21-bit words. For this we use base-8 (octal) notation because any 3-bit grouping can be represented by just one octal digit:
Octal = Binary
0 = 000
1 = 001
2 = 010
3 = 011
4 = 100
5 = 101
6 = 110
7 = 111
Octal notation varies from one programming language to another. Some append the letter 'o' while others might prefix a leading zero. So the 9-bit binary value 111100001 could be notated as 741o or 0741 depending on the language. By contrast, hexadecimal notation for the same value would be 0x1E1 or 1E1h.
You might ask why we don't just use hexadecimal notation for all binary values. We can certainly do that, but when we want to make it clear that we're specifically dealing with 3-bit groupings rather 4-bit groupings, it is best to use octal. In this case the hexadecimal notation implies a 12-bit value which could lead to confusion in our code. Whenever possible, we must strive to express our ideas directly in code.

What is a denary number?
A denary number is a number based on the ten digits, from 0 to 9. This is in contrast to the binary system used in computing, which consists entirely of 0s and 1s.
What is radix in number system?
The radix refers to the base of a number system: the total number of possible digits. The decimal number system that we all use is base ten, as it has ten distinct digits (0,1,2,3,4,5,6,7,8,9). Commonly used bases in computing include binary, octal, and hexadecimal, which have two, eight, and sixteen digits, respectively.
What is close system in System analysis?
close system are the type of system that do not interact with the environment
What is the importance os the Smith System?
The Smith System is the name given to a driving method that was developed by Harold Smith in 1948. The importance of the system is that it teaches safe driving methods to drivers of all different types of vehicles.
What is nyquist set?
The Nyquist stability criterion, named after Harry Nyquist, provides a simple test for stability of a closed-loop control system by examining the open-loop system's Nyquist plot. Under many circumstances, stability of the closed-loop control system may be determined directly by computing the poles of the closed-loop transfer function. In contrast, the Nyquist stability criterion allows stability to be determined without computing the closed-loop poles
Applications of number system?
Number systems used mainly in encoding, cryptography, digital computing.
When was ACM Computing Classification System created?
ACM Computing Classification System was created in 1964.
What is meant by processor in operating system?
the CPU (central processing unit) in a computer is the number-cruncher which is the core of any computing system.
Is cloud computing compatible with a Linux system?
Cloud computing is in fact compatible with the Linux operating system. If I'm not mistaken, you can actually do cloud computing on any operating system.
What is the definition of centralized computing system?
Computing done at a central location. (:
In computing what does NaN stand for?
When one is referring to computing NaN is said to stand for "Not a Number". This means that the monitoring system is not receiving any numeric data. This is often considered to be an error message.
What is the importance of Egyptian number system?
It is very important that you write it proerly.

What is the example of enterprise computing system?
Computing environment for the enterprise.The set of computer technologies (i.e. hardware, software, and practices) used in integrated large scale systems, which are made up of a group of computational entities, including mainframes, servers, and peripheral devices, interconnected by a network forming a virtual centralized computing facility.
What are the importance of DBMS in Commercial and Non Commercial Environment?
DBMS is a system software which helps in data collection, recording, and filing. Its importance in both commercial and non commercial environment include the assistance to any organization such that data can be extracted with ease.
