TYPES OF NUMBERS

1.Natural numbers
2.Whole numbers
3.integers
4.Rational numbers

*The counting numbers are called natural numbers.  The set of natural numbers is shown by N, is given by N = {1,2,3,4,….}

*All the natural numbers together with zero (0) are called whole numbers

The set W = {0,1,2,3,4,…..}


* The set of negative and positive numbers with zero is called integers.
    Z={…..-3,-2,-1,0,+1,+2,+3,….}

*RATIONAL NUMBERS: Numbers of the form like fraction i.e. p/q, where p and q are integers and q≠0, are called rational numbers

 some facts

Ø      Every natural number is a whole number

Ø      1 is the smallest natural number while 0 is the smallest whole number


Ø      Every natural number is a rational number, in general ‘n’ is a natural number, as n=n/1

Ø      Every integer is a natural number, as we can write, if ‘a’ is an integer, then a/1 is a rational number
Ø      Every fraction is a natural number, a/b is a rational number

LEARN COMPUTEER

COMPUTER


computer fundamentals



COMPUTER is an electronic device which takes input from the user through an input device, process the data through central processing unit  (unit), and gives the output  called information through output device.

Examples of input device:
          Keyboard, ….keyboard consists of letters, numbers, special characters and functional keys.   Keyboard is used to feed the data for various purposes. 

Exampeles of output device:

          VDU….visual display unit,  which is used to display the processed data, the information produced is meaningful and user friendly .
