A '''stack''' is a area of storage which is used to temporarily hold data in a 'push-down' fashion; i.e. data can be '''pushed''' onto the stack, and then '''popped''' off of it (in the reverse order from which it was pushed) when it is needed. (E.g. a 'push' of item A, and then B, would then be followed by a 'pop' of B, then A.)

Stacks are usually stored in [[main memory]], but in some modern machines with many [[register]]s, the top of the stack (or a [[cache]] of the top) may be held in them.

Modern [[CPU]]s generally dedicate one [[register]] to be a [[stack pointer]], to point to the top of the stack; and instructions usually have [[addressing mode]]s which allow source [[operand]]s to be popped ''from'' the stack, and the destination of the result to be a push ''onto'' the stack.
