In data structures, 'pop' refers to the operation of removing the top element from a stack. This action not only retrieves the element but also decreases the size of the stack, making it a critical function for managing data in a last-in-first-out (LIFO) manner. Understanding how pop works is essential for implementing stacks effectively, whether through arrays or linked lists, as it directly affects how elements are accessed and modified in these data structures.
