What Is LIFO (Last-In-First-Out) in IT?

November 6, 2023

LIFO (Last-In, First-Out) is a management method for items stored in data structures, such as stacks, queues, and function calls. According to the method, the last data element added to the data structure will be the first to be removed or processed. The concept is often utilized in IT, e.g., when managing the call stack (function calls in a program's execution), operating system tasks, or data in data structures (LIFO queues or LIFO stacks).
