The Festival International du Film Documentaire Océanien (FIFO), in English literally "International Oceanian Documentary Film Festival", is an annual film festival held on the French Polynesian island of Tahiti. Variant names in English include Pacific International Documentary Film Festival and International Documentary Film Festival of Oceania, but the event is commonly referred to in English as just FIFO, FIFO film festival, or FIFO Tahiti.

<algorithm> (FIFO, or "queue") A data structure or hardware buffer from which items are taken out in the same order they were put in. Also known as a "shelf" from the analogy with pushing items onto one end of a shelf so that they fall off the other. A FIFO is useful for buffering a stream of data between a sender and receiver which are not synchronised - i.e. not sending and receiving at exactly the same rate. Obviously if the rates differ by too much in one direction for too long then the FIFO will become either full (blocking the sender) or empty (blocking the receiver). A Unix pipe is a common example of a FIFO. A FIFO might be (but isn't ever?) called a LILO - last-in last-out. The opposite of a FIFO is a LIFO (last-in first-out) or "stack". (1999-12-06)

<operating system> A Unix pipe with a filename created using the "mknod" command. Named pipes allow unrelated processes to communicate with each other whereas the normal (un-named) kind can only be used by processes which are parent and child or siblings (forked from the same parent). (1996-12-01)

In computing, a named pipe (also known as a FIFO for its behavior) is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC). The concept is also found in OS/2 and Microsoft Windows, although the semantics differ substantially.

FiFo Records was an American record label established by singer-songwriters Bob Markley and Baker Knight in Los Angeles, California, in 1961. Following Markley's unsuccessful stint with Warner Bros.

FIFO and LIFO accounting are methods used in managing inventory and financial matters involving the amount of money a company has to have tied up within inventory of produced goods, raw materials, parts, components, or feedstocks. They are used to manage assumptions of costs related to inventory, stock repurchases (if purchased at different prices), and various other accounting purposes.

Fly-in fly-out is a method of employing people in remote areas by flying them temporarily to the work site instead of relocating employees and their families permanently. It is often abbreviated to FIFO when referring to employment status.
