    Well your question is not clear
    It should be data abstraction & or something else

    Well any how, abstraction means to hide certain details(details which are meaning less to user or very critical example how the programs stores result where it stores & so on) from the casual user so that he can't harm or malfunction the critical details. Only in the object oriented language we use the data abstraction feature.

      Abstraction is extraction of essential properties.It is one of the important concepts in Object Oriented Technology.Let me explain to you with an example: Instead of identifying a person by telling this guy,he z six feet tall,a little fat,fair n all,v identify him with the help of his name.Like,name is enough to identify him(Essential property),This is Abstraction.
