It stems from the analogy of a plate-stacker. That is; a recessed pit with a spring-loaded platform that pushes upwards. As plates are stacked onto the platform, the spring is compressed by the weight of the plates, pushing the platform down into the pit so only the top plate protrudes from the pit. When the top plate is removed, the stack pops up to expose the next plate.
The push and pop verbs apply to all linear sequence containers where a new element can be added at the front and/or back ends of the sequence, such as arrays/vectors, lists, queues and stacks.

Can stack be called fifo data structure?
No. A stack is a LIFO (Last In First Out) data structure.A queue is a FIFO (First In First Out) data structure.
What is push operation in data structure?
Push inserts a value onto the top of the stack. Pop extracts the top value from the stack. These are the two primary operations that can be performed upon a stack. Prior to popping a value, you will first check the stack is not empty, store the top value, then pop the stack. For a stack of type T, you might use the following: if (!stack.empty()) { T value {stack.top()}; // copy top value stack.pop(); // remove value from stack // use value... }

What is a stack in data structure?
A stack in Data structure is a LIFO structure. Last In First Out. Think of it as a stack of books or a stack of trays in a cafeteria line. when you are in a line in a cafeteria you take the tray that is on the top and the worker place new washed ones also on the top. So deletion and insertion all done at one end, it is called the top of the stack. In Computer Programming Stacks are so important and have too many applications such as the evaluation of Mathematical expressions. Also note that a stack is unlike a queue structure. Queue data structure is FIFO. First In First Out as in a bank teller line.

What does pop mean in math form?
In mathematics, "pop" often refers to the operation of removing an element from a data structure, such as a stack or a queue. For example, in a stack, "pop" removes the top element and typically returns it, reducing the size of the stack by one. This operation is fundamental in various algorithms and data management tasks. In a more general sense, "pop" can also denote the act of extracting or discarding an item from a collection.
What data structure the pushand pop?
Push and pop are properties of a stack (also called a LIFO-- Last In, First Out-- queue).
What are some common operations that can be performed on a stack data structure?
Common operations that can be performed on a stack data structure include push (adding an element to the top of the stack), pop (removing the top element from the stack), peek (viewing the top element without removing it), and isEmpty (checking if the stack is empty).
What are the important applications of stacks?
In computer science, a stack is an area of memory that holds all local variables and parameters used by any function, and remembers the order in which functions are called so that function returns occur correctly. Each time a function is called, its local variables and parameters are "pushed onto" the stack. When the function returns, these locals and parameters are "popped." Because of this, the size of a program's stack fluctuates constantly as the program is running, but it has some maximum size.One way of describing the stack is as a last in, first out (LIFO) abstract data type and linear data structure. A stack can have any abstract data type as anelement, but is characterized by two fundamental operations, called push and pop (or pull). The push operation adds a new item to the top of the stack, or initializes the stack if it is empty. If the stack is full and does not contain enough space to accept the given item, the stack is then considered to be in anoverflow state. The pop operation removes an item from the top of the stack. A pop either reveals previously concealed items, or results in an empty stack, but if the stack is empty then it goes into underflow state (It means no items are present in stack to be removed). A stack pointer is the register which holds the value of the stack. The stack pointer always points to the top value of the stack.A stack is a restricted data structure, because only a small number of operations are performed on it. The nature of the pop and push operations also means that stack elements have a natural order. Elements are removed from the stack in the reverse order to the order of their addition: therefore, the lower elements are those that have been on the stack the longest
How can you add different type of data in a stack?
stack is a linear data structure in which data item is either inserted or deleted at one end there are mainly two operations performed on stack.they're push poppush:writing a value to the stack is push or moving the stack pointer up to accomodatethe new item. pop:reading a value from stack or moving the stack pointer down.
Why is the queue data structure called a LIFO?
It isn't! A queue is a FIFO structure, not a LIFO structure. FIFO is an acronym for First-In, First-Out and is analogous with first come, first served (as per a queue of people waiting to be served). LIFO is an acronym for Last-In, First-Out, which is analogous with a stack structure, where the last element added is always placed on top of the stack while the top-most element of the stack is always the first to be removed from the stack.
