stack

(programming)(See below for synonyms) A data structure forstoring items which are to be accessed in last-in first-outorder.

The operations on a stack are to create a new stack, to "push"a new item onto the top of a stack and to "pop" the top itemoff. Error conditions are raised by attempts to pop an emptystack or to push an item onto a stack which has no room forfurther items (because of its implementation).

Most processors include support for stacks in theirinstruction set architectures. Perhaps the most common useof stacks is to store subroutine arguments and returnaddresses. This is usually supported at the machine codelevel either directly by "jump to subroutine" and "return fromsubroutine" instructions or by auto-increment andauto-decrement addressing modes, or both. These allow acontiguous area of memory to be set aside for use as a stackand use either a special-purpose register or a generalpurpose register, chosen by the user, as a stack pointer.

The use of a stack allows subroutines to be recursive sinceeach call can have its own calling context, represented by astack frame or activation record. There are many otheruses. The programming language Forth uses a data stack inplace of variables when possible.

Although a stack may be considered an object by users,implementations of the object and its access details differ.For example, a stack may be either ascending (top of stack isat highest address) or descending. It may also be "full" (thestack pointer points at the top of stack) or "empty" (thestack pointer points just past the top of stack, where thenext element would be pushed). The full/empty terminology isused in the Acorn Risc Machine and possibly elsewhere.

In a list-based or functional language, a stack might beimplemented as a linked list where a new stack is an emptylist, push adds a new element to the head of the list and popsplits the list into its head (the popped element) and tail(the stack in its modified form).

At MIT, pdl used to be a more common synonym for stack,and this may still be true. Knuth ("The Art of ComputerProgramming", second edition, vol. 1, p. 236) says:

Many people who realised the importance of stacks and queuesindependently have given other names to these structures:stacks have been called push-down lists, reversion storages,cellars, dumps, nesting stores, piles, last-in first-out("LIFO") lists, and even yo-yo lists!

stack

(1) In a network, a hierarchy of software layers in both clients and servers that are required in order to communicate with each other. See protocol stack.

(2) A hierarchy of software. A stack is the common set of programs used in a computer. The stack can refer to infrastructure only (see technology stack) or to the applications the company gives its employees (see application stack). It may also refer to an industry set or developer set of programs. For example, the phrase "they don't offer a complete stack" could imply that a software company has an incomplete set of applications for a particular industry or niche.

(3) 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.

(4) A Macintosh folder view (see Stacks).

(5) An earlier Macintosh development system (see HyperCard).
