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.


With data structures what are the implementations of using LIFO and FIFO?

Think about what each concept means. A FIFO (First In, First Out) stack is like a supermarket queue - people are served in the order in which they arrive in line. You'd use a FIFO stack for a process that requires sequential access to data in arrival order, such as transaction processing. On the other hand, a LIFO (Last In, First Out) stack is like an elevator - the people who board last are nearest the front, so they're the first off in "processing" order. You might use a LIFO stack for something like expression parsing. For example, if you're trying to match up parens, you need to use the "nearest match" rule. That means if you have already stacked two "("s you'd want to pair the most recently-scanned one with the first closing ")" encountered and evaluate the enclosed expression. That means the ")" would pair off with the "(" at the top of your paren stack rather than the bottom; i.e. LIFO.


Why filo is not used in stack?

FILO is an acronym of "first in last out". If we imagine a stack of plates, the first plate is at the bottom of the stack and is therefore the last to be removed from the stack. Thus FILO is used when referring to a stack. We use a stack when we wish to process elements in the reverse order they arrive, always processing the newest arrival first. Stacks are useful in backtracking algorithms and are a fundamental aspect of the call-and-return mechanism. FIFO, on the other hand, is an acronym of "first in first out" and is synonymous with "first come, first served". As such, FIFO applies to queues rather than stacks. We use a queue when we wish to process elements in the same order they arrive.


What is FIFO approach?

FIFO is the acronym for First In First Out, which means Use (or do) the Oldest Stuff First, or use things in the order of their arrival. Two common contexts for this are in accounting and computing. FIFO is also used in inventory and in stocking shelves where the items that are received first should be used first and old items are shelved in front and new items in the back. It is a materials management technique in Warehousing, Fruit & Vegetable stores, Butcher shops, etc. and handling incoming mail in offices. It is all about making sure things flow through a system properly, where older items are used before items that have just come in. Technically, FIFO is a means of describing a queue-like data sequence, where insertions (push operations) occur at the end of the sequence and extractions (pop operations) occur at the beginning of the sequence. As opposed to a LIFO (last-in, first-out) sequence where all pushes and pops occur at the end of the sequence, thus creating a stack-like data sequence. LIFO can also be called FILO (first-in, last-out), which means the same thing. In other words, with FIFO, we pop objects off the sequence in the same order they were pushed onto it, but with LIFO/FILO we pop objects in the reverse order they were pushed.

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.


Is stack of 8086 FIFO?

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.)


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).

Does Toyota use FIFO?

Yes, Toyota uses FIFO. FIFO stands for first in, first out, this means that things put in first can be taken out and used first when building a car. Toyota is not the only company to use FIFO.


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.
