The Decimal Number System consists of ten digits from 0 to 9. These digits can be used to represent any numeric value. The base of decimal number system is 10. It is the most widely used number system Number systems with 2k bases have an interesting property in that the conversion between them can be achieved without the computation of Eq. (1). Such number systems include binary, octal, hex, and base-32 number systems. Note that since these number systems possess base 2k, all numbers within these systems can be uniquely represented by k.

Binary Numbers •The hexadecimal system, or Hex, uses base 16, therefore there are 16 possible digit symbols. The hexadecimal system groups binary number by 4's and from 0 to 9 it is the same as a decimal number equivalent in binary form. This means 0000 is 0, 0001 is 1, 0010 is 2 and so on to 100

Number system pdf- Definition,Types of number systems
Decimal numbers like this are said to be expressed in a number system with base , or radix , 10 because there are 10 basic digits (0, 1, 2, , 9) from which the number system is formulated. In a similar fashion we can express any number N in a system using any base b. We shall write such a number as ( N )b. Whenever ( N )b is written Any real number that is divisible by 1 and itself come under this category. Example of prime numbers 2, 3, 5, 7, 11.

A number system that uses eight different digits to represent different values is known as octal number system. The base of octal number system is 8 because it consist eight digits from 0 to 7. The octal number system is used in the computer to represent binary numbers. The place values in the octal number can be expressed by using powers of 8 No notes for slide. Number Systems 1. Number Systems Number Systems Two types of number systems are: Non-positional number systems• Positional number systems• Bit • Bit stands for binary digit • A bit in computer terminology means either a 0 or a 1 • A binary number number consisting of n bits is called an n-bit 14 Computer systems make use of the electronic component referred to as bits, which can only represent two symbols {0, 1}. This leads to the use of the placeholder system with base 2, also called the binary system. The binary system leads to very long numbers, which is inconvenient for humans to read and write The binary system is a number system that has just two unique digits, 0 and 1. A bit also know as binary digit, is the smallest unit of data the computer can process. A byte is when eight bits are grouped together as a unit
