Set Theory starts very simply: it examines whether an object belongs, or does not
 
belong, to a set of objects which has been described in some non-ambiguous way.
 
From this simple beginning, an increasingly complex (and useful!) series of ideas

can be developed, which lead to notations and techniques with many varied

applications. A set can be defined as a collection of things that are brought

together because they obey a certain rule.These 'things' may be anything you
 
like:
 
numbers, people, shapes, cities, bits of text ..., literally anything.The key fact

about the 'rule' they all obey is that it must be well-defined 

hope it helps............. :)

1  the collection of all  boys in your class  =   set .
2  the team of eleven best  cricket batsmen  of the world = not set.
  for   example.
natural number, prime number  quadrilaterals in a  plane etc.  all   example  see  so  far  are well defined  collection of objects or  ideas. a well defined collection of onjects or ideas is known  as a set.  set  theory is a comparitively new concept in mathematics..

all the objects  in the set should have a common feature or property...

hope its help u..
