Usually not, but it depends on the context, I mean what kind of stack are you talking about. For example in FORTH language word PICK and ROLL could be used.
A cylinder. Each track on each platter can be thought of as being a ring, thus if you isolated the same track upon each platter you'd have a stack of imaginary rings which would therefore form an imaginary cylinder.
A stack created by the user or a programmer is an implicit stack
A stack is a data structure in which last item inserted is taken out first . That's why they are known as LIFO (last in first out). Inserting an item in stack is termed as push and taking an item out from stack I s termed as pop. Stack pointer is the pointer that points to the top of the stack or that points the item at the top of the stack and help in adding or deleting the item from the top of stack.
