Similarly to a stack of plates, adding or removing is only practical at the top. Simple representation of a stack runtime with push and pop operations. In computer science, a stack is an abstract data type that serves as a collection of elements with two main operations: Push, which adds an element to the collection, and
An algebraic stack or Artin stack is a stack in groupoids X over the fppf site such that the diagonal map of X is representable and there exists a smooth surjection ...
Call stack layout for upward-growing stacks after the DrawSquare subroutine (shown in blue) called DrawLine (shown in green), which is the currently executing routine. A call stack is composed of stack frames (also called activation records or activation frames).
The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).
Stack machine, an architecture centered around a pushdown stack; Protocol stack, a particular software implementation of a computer networking protocol suite; Solution stack, a group of software systems, increasing in abstraction from bottom to top; Stack-based memory allocation, a memory allocation scheme based on the principle of "last in ...
The stack easily holds more than two inputs or more than one result, so a rich set of operations can be computed. In stack machine code (sometimes called p-code), instructions will frequently have only an opcode commanding an operation, with no additional fields identifying a constant, register or memory cell, known as a zero address format.

Here's the net worth you need in 2025 to rank in the top 25%, 10%, 0.1% of Americans — how do you stack up right now? Chris Clark. January 16, 2025 at 7:02 AM.
In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...
