A stack is basically memory where you store data temporarily. When you call a function in C, it pushes the data on the stack, after the function returns, it pops it off. The stack is only a certain size and it is possible to push more data onto it than there is memory. I guess that's when an overflow occurs, I don't know what's making it overflow from what you've posted.

The two actions relate to the stack are push and pop.
