Stack (abstract data type)
A stack, also called a push-down store, is an abstract data type where only the most recently added item may be removed, following last-in, first-out order.
Stack (mathematics)
In algebraic geometry, a stack is a category fibred in groupoids over schemes that behaves like a sheaf of geometric objects, introduced by Deligne and Mumford in 1969 to solve moduli problems with automorphisms.
Stack algorithm (sequential detection)
The stack algorithm, also called the Zigangirov–Jelinek (ZJ) algorithm, is a sequential decoding method that keeps explored paths in a metric-sorted stack; it was introduced by Zigangirov in 1966 and independently by Jelinek in 1969.
Stack effect
Stack effect, also known as chimney effect or natural draught, is the movement of air through buildings driven by temperature-based density differences between indoor and outdoor air.
Stack Exchange
Stack Exchange is a network of question-and-answer websites, started in 2008, where users ask questions, answer them, and earn reputation and badges; its largest site is Stack Overflow.
Stack machine
A stack machine, also called a stack computer, is a computer or virtual machine whose instructions take operands from a last-in, first-out stack rather than named registers.
Stack overflow
A stack overflow is a runtime fault where a program's call stack exceeds its allocated memory, typically crashing the program, most often caused by unbounded recursion.
Stack Overflow
Stack Overflow, the largest site in the Stack Exchange network, is a programming question-and-answer website launched in 2008 and acquired by Prosus in 2021 for about $1.8 billion.

Stack ventilation, sometimes called buoyancy ventilation or the stack effect, is a passive ventilation method in which rising warm air pulls fresh outdoor air in through low-level openings.
Stack-oriented programming
Stack-oriented programming is a style of programming in which operations take their arguments from a stack rather than named variables; its best-known language is Forth.
Stacked CMOS image sensor
A stacked CMOS image sensor bonds a light-capturing pixel chip and a signal-processing circuit chip on top of each other, introduced by Sony in 2012.
Stacked ensemble learning
Stacked ensemble learning, or stacking, is a machine learning method in which a second-level meta-learner is trained on the predictions of several base models, introduced by David Wolpert in 1992.
Stacked ensemble model
Stacked ensemble model (stacking) is a supervised machine learning method that trains a second-level meta-model on the predictions of diverse base models to achieve higher accuracy.
Stacked generalization
Stacked generalization, or stacking, is an ensemble method in machine learning that trains a meta-learner on the outputs of base models, proposed by David Wolpert in 1992.
Stackelberg game
A Stackelberg game is a game-theoretic model of hierarchical decision-making in which a leader commits to a strategy first and the follower best-responds, applied in economics and security.
