No. It is a LIFO.
(FIFO means first-in-first-out. LIFO means last-in-first-out. A FIFO is a queue, such as a group of people standing in line to buy theater tickets. A LIFO is a different sort of queue, such as a nested interrupt and/or subroutine call stack, where each entry preempts the prior entry.)

Why does not use FIFO in stack?
A FIFO, or First In First Out is a queue.A stack is a LIFO or Last In First Out.
Why does LIFO order follows in stack and why does FIFO order follows in queue?
LIFO and stack are synonyms, so are FIFO and queue.
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 difference between stack snd queue?
In stack , the object which is last in will be first out (LIFO), whereas in queue the object which is first in will be first out (FIFO).
What makes up a stack?
A stack is usually a sequential series of instructions of any reasonable length. Access to a stack can be FIFO(First In First Out), LIFO (Last In First Out) or by access to any point in the stack by use of a pointer.
Which register can be changed directly using pop instruction in 8086?
stack segment register
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.
What is the SP pointing register's default memory segment?
The default segment for SP (Stack Pointer) relative memory accesses in the 8086/8088 is SS (Stack Segment).
What is the application of stack in computer science?
A stack is a series of storage locations for data or instructions. These can be popped off the stack as needed, and pushed down onto the stack to be stored. They can be accessed in a LIFO or FIFO fashion.
How many base registers are there in 8086?
There are four base registers in the 8086/8088; Code Segment (CS), Data Segment (DS), Stack Segment (SS), and Extra Segment (ES).
Difference between a queue and a stack in brief?
In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).
What is the basic difference between instruction RET and IRET in 8086 microprocessor?
RET pops the PC off of the stack, while IRET pops both the flags and the PC off of the stack.
