  Stack (data structure) - Wikipedia, the free encyclopedia
Stack pointers may point to the origin of a stack or to a limited range of addresses either above or below the origin (depending on the direction in which the stack grows); however, the stack pointer cannot cross the origin of the stack.
Stacks are either visualized growing from the bottom up (like real-world stacks, see image, or, with the top of the stack in a fixed position, a coin holder [1]) or growing from left to right, so that "topmost" becomes "rightmost".
A stack is usually represented in computers by a block of memory cells, with the "bottom" at a fixed location, and the stack pointer holding the address of the current "top" cell in the stack.

In the design of many types of programs, the choice of data structures is a primary design consideration, as experience in building large systems has shown that the difficulty of implementation and the quality and performance of the final result depends heavily on choosing the best data structure.
After the data structures are chosen, the algorithms to be used often become relatively obvious.
A data structure can be viewed as an interface between two functions or as an implementation of methods to access storage that is organized according to the associated data type.

 Definition of Stack   (Site not responding. Last check: 2007-10-29)
A stack is a type of data structure -- a means of storing information in a computer.
In other words, the stack data structure is just like a stack of cards, papers, credit card mailings, or any other real-world objects you can think of.
These connections, or layers, act like the stack data structure, in that they are built and disposed of in the same way.

A stack structure restricts dramatically how elements are inserted, retrieved, and removed: The most recently inserted element in the stack is the only one that can be retrieved or removed.
A good real-life example of a stack is the pile of dinner plates that you encounter when you eat at the local cafeteria: When you remove a plate from the pile, you take the plate on the top of the pile.
A stack is the ideal data structure for evaluating an arithmetic expression written in postfix notation.

The stack is a common data structure for representing things that need to maintained in a particular order.
Conceptually, a stack is simple: a data structure that allows adding and removing elements in a particular order.
In fact, the "call stack" is the term used for the list of functions either executing or watiing for other functions to return.

STACK POINTER A STATIC MEMORY Pre-allocated by the compiler (at compile time) Bibliography ------------ On simulating recursion: Data structures using Pascal (2nd edition) Aaron M. Tenenbaum, Moshe J. Augenstein Prentice-Hall 1986 ISBN 0-13-196684-7 Introduction ------------ Recursion is calling a procedure from itself, directly (simple recursion) or via calls to other procedures (mutual recursion).
The stack data structure ------------------------ A stack is a sequence of memory locations with an associated STACK POINTER that points to the 'current location', a stack can be manipulated by two operations: PUSH and POP.
Stacks (like main-memory) are really one-dimensional entities, they go from location 0 to location N, N is supposed to be large enough for the task on hand ('real' stacks may go from -N to 0).

 Stack Groups
It is the main data structure behind the implementation of a process.
This data is set up when the stack group is created and doesn't normally change during the course of system operation.
This information is loaded when the stack group is entered; but since it doesn't change, the data needn't be saved when the stack group is left.

 Stack - Array Implementation
By data structure, we mean something that is meant to hold data and provides certain operations on that data.
Now, there are 2 main parts to a C data structure: the data types needed to keep track of a stack and the functions needed to implement stack operations.
They are not part of the abstract concept of a stack, but they are necessary for setup and cleanup when writing the stack in C. Finally, while the array that holds the contents of the stack will be dynamically-allocated, it still has a maximum size.

The stack data structure and its use are described in the stacks lecture.
In the implementation of stacks, we define what our stack type really is. When we create a stack using new_stack(), we will allocate one of our own stacks, and then pass it to the caller as a (void *).
So, stack_push(j) must be written so that it takes a stack with size nodes, and turns it into a stack with size+1 nodes, the first of which is a new node with a val of j.

Stack is a dynamic set where the elements are added to the top of the set (Push) and deleted from the top of the set (Pop).

In Unix speak, it is similar to a daemon able to funnel data between applications and the shell itself.
As a data structure, it is a more elaborate than a regular stack because 1.
The stack scope can be internal to the application (as usual), or the Stack can run as a daemon to enable sharing of data between network applications, or you could use both the internal plus the networking stacks at the same time.
