Stack of Data Structure

Definition

In computer science, a stack is a temporary abstract data type and data structure based on the principle of Last In First Out (LIFO).

Stacks are used extensively at every level of a modern computer system.

For example, a modern PC uses stacks at the architecture level, which are used to run an operating system.

The operating system also uses stacks, which are used to run a Java Virtual Machine, which is stack oriented, and the Java language itself has a class called "Stack", which can be used by the programmer.

The stack is ubiquitous.
