Hexadecimal Number System forms the backbone of the digital system such as microprocessors, microcontrollers etc. It is a number system which consists of 16 elements, in which 10 numbers from 0 to 9 and 6 alphabets from A to F are used. Any other number can be represented in the hexadecimal number system with the help of the combination of these 16 elements. The word hexadecimal is formed from two words, “HEX” and “DECIMAL”. Hex means 6 and decimal mean 10, the sum of these two is 16 which … [Read more...] about Hexadecimal Number System

## Octal Number System

The octal number system is a number system which uses eight digits to express any number. The digits used are 0, 1, 2, 3, 4, 5, 6 & 7. All the other digits can be expressed using these 8 digits. You will never see 8 or 9 in any of the numbers in the octal system. The base of the octal number system or radix is 8. This is because the total number of digits in the number system is 8. The positional value of the digits in the octal system can be written in terms of 8 raises to the power the … [Read more...] about Octal Number System

## Binary Number System

Binary Number System comprises of two digits 0 & 1, thus, the base of the binary number system is 2. Thus, it is called as a base-2 system. It is much easier and simpler than decimal number system because it is comprised of only two digits. In binary number system, any number can be expressed by array of numbers in which each coefficient is calculated by successive power of 2. The representation of decimal numbers is done by expressing the digits of the number in power of 10. Similarly in … [Read more...] about Binary Number System

## Decimal Number System

The decimal number system comprises of digits from 0-9 i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8 & 9. The base or radix of the decimal number system is 10 because total number of digits available in decimal number system is 10. It doesn’t imply that these 10 digits will represent only 10 quantities, but all the other digits can be expressed with the help of these numbers. Decimal number system is the most common number system which we use in our daily lives. If we want to deal with digital system … [Read more...] about Decimal Number System

## Number System

Computers understand machine language. Every letter, symbol etc. that we write in the instructions given to computer, it gets converted into machine language. This machine language comprises of numbers. In order to understand the language used by computers and other digital system it is crucial to have a better understanding of number system. Number systems can be classified into its sub-types on the basis of base of that system. Base of a number systems plays crucial role in understanding … [Read more...] about Number System
