(1) A Macintosh folder view (see Stacks).
(2) A set of hardware registers or a reserved amount of memory used for arithmetic calculations, local variables or to keep track of internal operations (the sequence of routines called in a program). For example, one routine calls another, which calls another and so on. As each routine is completed, the computer returns control to the calling routine all the way back to the first one that started the sequence. Stacks used in this way are LIFO based: the last item, or address, placed (pushed) onto the stack is the first item removed (popped) from the stack.
Stacks are also used to hold interrupts until they can be serviced. Used in this manner, they are FIFO stacks, in which the first item onto the stack is the first one out of the stack. See internal stack failure, stack dump and stack fault.
