hello wht's the meaning of 'first in first out'?

Answer 1

Meaning you get somewhere first, do what you need to do before everyone else and leave first

Answer 2

It depends on the application, but generally it means that the first one that is in a line/queue, the first one that comes out. Think of a shopping line at a grocery store or ticket counter. The first person to get in line is the first person served, then the second person, and so on. Its opposite is last in, first out, which (at least in computer programming) is how a stack is implemented. In this case, thing of a stack of objects on a table. The last one you put on the stack is the first one you take off the stack; you don't (generally) reach to the bottom of the stack and pull the first one out.

The concepts have several different applications - everything from computer programming to accounting to interest on a bank account.

Answer 3

FIFO is an acronym for First In, First Out. This expression describes the principle of a queue or first-come, first-served (FCFS) behaviour: what comes in first is handled first, what comes in next waits until the first is finished, etc. Thus it is analogous to the behaviour of persons queueing (or "standing in line", in common American parlance), where the persons leave the queue in the order they arrive. FCFS is also the other name for the FIFO operating system scheduling algorithm, which gives every process CPU time in the order they come.

A priority queue is a variation on the queue which does not qualify for the name FIFO, because it is not accurately descriptive of that data structure's behavior. Queueing theory encompasses the more general concept of queue, as well as interactions between strict-FIFO queues.

The expression FIFO can be used in different contexts.

Answer 4

First in last out stems from the sixties early seventies
When the unions insisted that the person with the longest time in the work place was the last person to be selected for redundancy.
This no longer can happen

Answer 5

It usually a memory buffer to help data lines that work at different speeds. Data is queued in the FIFO buffer to allow as far as possible the respective data lines to keep doing their thing as efficiently as possible. for example data is might be from a dial up modem and data out might be written to hard drive. Writing to a hard drive is much faster than com port communication from a modem. So then a FIFO buffer is used by a device to queue data. To keep things in order the first data in is the first data out, thus the term "FIFO"

Answer 6

It means the first person to arrive, gets seen to and then can leave first. It's usually referring to situations where you normally have to wait, like a government office, emergency room, etc.
Another colloquial expression for the same thing is; "First in, best dressed."

Answer 7

"First in, first out" or FIFO, and "Last in, first out" or LIFO are actually inventory accounting procedures.

FIFO refers to valuating the goods going out of the warehouse based on the price of the oldest (or first in) purchases.

LIFO refers to valuating the goods going out of the warehouse based on the price of the latest (or last in) purchases.

In climates of rising prices (which is often the case), LIFO valuation is considered the more conservative policy than FIFO.

Answer 8

I think you mean last in first out
used in employment if staff is being cut back the newest people are the first to go

Answer 9

Sales talk. First in queue gets served and is first to leave.

Answer 10

Just like Emma said.
She was first in and first out on this answer for example.
