A framework is nothing but a set of assumptions,the way how 
the environment is.
           plz,if i am wrong,plz explain me clearly

Framework is underline layer which provide different 
functionalilty to the user in very high level abstraction.

You can find a lots of framework in market, like in 
java, .Net, Symbain etc..,

One example of features provided by framework is client 
server intraction in case of symbain OS, suppose you are 
transfering some data from client to server or vise versa,
since client and server are in diffrent processes, we need 
IPC for that. but what S60 framework (symbain OS) do, it 
handle all that internally. user has to simply call and API 
and data is transferd to the server.

above is only one small example, but framework provide many 
of such things to the user.
