cui il primo oggetto introdotto è il primo ad uscire. Un esempio di immagine rappresentativa del concetto è quella di un tubo con una estremità da cui entrano gli oggetti e l'altra dalla quale escono. L'ordine di uscita è uguale a quello di entrata.<br />Si può esemplificare con un dispenser di prodotti in un supermercato, in cui gli articoli vengono introdotti dall'alto ed il cliente li preleva dal basso, permettendo la rotazione di tutti i prodotti; o più semplicemente una serie di persone che disposte in fila indiana attendono di essere servite al bancone di una biglietteria. </p><p>Il metodo FIFO si contrappone al metodo <a href="/wiki/LIFO" title="LIFO">LIFO</a> (Last In First Out, cioè "ultimo ad entrare, primo ad uscire"), in cui è l'ultimo oggetto inserito ad essere estratto per primo. </p> <div class="mw-heading mw-heading2"><h2 id="Contabilità_e_logistica"><span id="Contabilit.C3.A0_e_logistica"></span>Contabilità e logistica</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=FIFO&veaction=edit&section=2" title="Modifica la sezione Contabilità e logistica" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=FIFO&action=edit&section=2" title="Edit section's source code: Contabilità e logistica"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Il metodo FIFO è uno dei possibili metodi per la valorizzazione delle scorte di <a href="/wiki/Magazzino" title="Magazzino">magazzino</a>. </p><p>Consiste nel valorizzare gli scarichi del magazzino a partire dai primi carichi effettuati, ad esempio: </p><p><i>Il giorno 15 di ogni mese si ricevono merci da un fornitore, che vengono poi rivendute. A fine anno vengono valorizzate con il metodo FIFO.</i> </p><p>Supponiamo che siano state vendute esattamente metà delle merci. Con il metodo FIFO calcoleremo come vendute (e quindi scaricate) le merci acquistate da gennaio a giugno compreso, perché sono le prime in ordine cronologico. Le rimanenti merci in magazzino corrisponderanno alle quantità acquistate e non vendute da luglio a dicembre. </p><p>In fase di valutazione del magazzino risulta importante scegliere il metodo da utilizzare, poiché i risultati possono variare anche di parecchio (se, ad esempio, vi sono state grosse fluttuazioni nei prezzi delle merci considerate nel corso dell'esercizio). </p><p>In logistica è in genere logico e razionale utilizzare il metodo FIFO nel flusso logistico, in quanto le prime merci o materie prime arrivate dovranno essere le prime ad essere consumate, per evitarne l'obsolescenza, o addirittura la scadenza (per le merci deperibili); per questo motivo è noto anche con il nome di FEFO (<i>First Ended</i> (o <i>expired</i>)<i>, First out</i>). </p> <div class="mw-heading mw-heading2"><h2 id="Elettronica">Elettronica</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=FIFO&veaction=edit&section=3" title="Modifica la sezione Elettronica" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=FIFO&action=edit&section=3" title="Edit section's source code: Elettronica"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Il concetto è impiegato in <a href="/wiki/Memoria_(informatica)" title="Memoria (informatica)">memorie</a> utilizzate come <a href="/wiki/Buffer" title="Buffer">buffer</a> per regolare il flusso di dati tra <a href="/wiki/Periferiche" class="mw-redirect" title="Periferiche">periferiche</a> a differente velocità, ad esempio tra memorie <a href="/wiki/RAM" title="RAM">RAM</a> e <a href="/wiki/Microprocessore" title="Microprocessore">processore</a>.
