### types of numbers

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 Ã˜      Every natural number is a whole number Ã˜      1 is the smallest natural number while 0 is the smallest whole number Ã˜      Every natural number is a rational number, in general ‘n’ is a natural number, as n=n/1 Ã˜      Every integer is a natural number, as we can write, if ‘a’ is an integer, then a/1 is a rational number Ã˜      Every fraction is a natural number, a/b is a rational number

## 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 .

## how a computer can understand us ?

computer knows only machine language. we need to convert high level language into machine language.  Machine language is in binary digits 0's and 1s.  Any thing what we are giving as input is converted into binary form.

PROGRAM: A set of instructions is called a program.

HIGH LEVEL LANGUAGES :  Earlier days we have COBOL, BASIC, etc.  But now a days every one is using Python, C, C++, etc. due to requirement and necessity of the people we are shifting to new languages.

IN OUR TUTORIAL, WE ARE PROVIDING VIDEOS ALSO TO UNDERSTAND CLEARLY.

Abrasion A Phenomenon of wearing off because of friction Absolute scale The zero of this scale of temperature corresponds to absolute zero. Absolute zero Zero of thermodynamic temperature (0 kelvin) Absorption hygrometer A device that is used for measuring the humidity of air Acceleration due to gravity(g) It is the uniform acceleration produced in a freely falling body due to the gravitational pull of the earth. Accumulator A type of voltaic cell or battery that can be recharged by passing a current through it from an external d.c. supply. Acceleration (a) The rate of change of speed or of velocity Accelerator A machine used for producing high energy charged particles and studying nuclear reactions. Acceptor Materials that are used for doping semiconductors whose atoms accept electrons form neighbouring atoms known as host Achromatic colour A colour that has no colour Acoustics Refers to the study of the production and properties of sounds Actinometer Referes to any of various instruments for measuring the intensity of electromagnetic radiation. Active device An electronic component such as a transistor that is capable of amplification Adapter A device that is used for connecting parts of different size and shape Admittance It is a measure of the ability of a circuit to conduct an alternating current.

Alloy A mixture of two or more metals or of a metal with small amounts of non-metals. Alnico Used to make permanent magnets. Alternating current (A.C.) A current which flows alternately in one direction, then in the opposite direction around a circuit. Alternating voltage The voltage whose magnitude and direction change with time and after a certain time the voltage recur with the same magnitude and in the same direction is called alterating voltage Amalgam An alloy of mercury with one or more other metals Ammeter A meter used to measure electric current. Ampere The ampere is the practical unit of electric current.
