hi

There will be no change in memory area .And all the major part will be taken by the stack pointer.It depends on the calling conventions like pascals convention or any other depending on the parameters passed by the function.

The data is stored in registry.

There will be a lot of changes in fact. First of all all the variables the function was suing needs to be pushed into the stack. (we need all these variables when we return from the other function). The Program counter will be pushed to stack too... (When the return of second function occurs we should know where to 'return' to)These are the basics which are bound to happen when a function calls another.
