confused about system stack
I am confused about the term "stack" which the system will use -- there are so many items we call them "stack". Suppose when we invoke a function, we will push the parameters and return address into a "stack", so that when the function returns, it can find the address to proceed correctly. Is it the same as a data structure "stack".
When we create a variable using malloc or new, we also say that it is allocated on "heap" other than on "stack", is heap also something like a stack in ternally (but has a different term)? And for local variables, when they are created, we say it is created on stack (for example, int i, j; ), it seems that each function has a separate stack?
Another confusing thing is thinking about stack and segment together, like the code segment, data segment of the program (which you can see when debugging your application), are the segments also some stacks (since when local variables are on code segment, we also say local variables are on stack, so I think maybe segment is implemented as stack)?
Besides the "stacks" I presented above, are there any other stacks which system will utilize?
Please forgive asking a simple question. :-)
