The behavior that ADT (abstract data type) stack exhibit is last-in-first-out.
Abstract Data type (ADT) refers to a type or class for objects whose behavior is described by a set of values and a set of operations. The ADT definition only defines the type operations to be performed but not the way these operations will be implemented. Stacks and queues are commonly used in programming languages and are types of ADT that can be used to store and retrieve data in different ways. Stacks have a last-in-first-out mechanism (LIFO), whereas Queues have a first-in-first-out mechanism (FIFO). There are two types of stacks - register stack and the memory stack.
