Computer science or computing science is the study of the theoretical foundations of information and computation and of practical techniques for their implementation and application in computer systems...

, FINO is a humorous scheduling algorithm. It is an acronym for "First In Never Out" as opposed to traditional "first in first out" (FIFO) and "last in first out" (LIFO) algorithms.

FINO works by withholding all scheduled tasks permanently. No matter how many tasks are scheduled at any time, no task ever actually takes place. This makes FINO extremely simple to implement, but useless in practice. A stateful

State (computer science)

In computer science and automata theory, a state is a unique configuration of information in a program or machine. It is a concept that occasionally extends into some forms of systems programming such as lexers and parsers....

 FINO queue can be used to implement a memory leak

Memory leak

A memory leak, in computer science , occurs when a computer program consumes memory but is unable to release it back to the operating system. In object-oriented programming, a memory leak happens when an object is stored in memory but cannot be accessed by the running code...

A mention of FINO appears in the Signetics 25120 write only memory

Write Only Memory

Write-only memory is the antithesis of read-only memory . By definition, a WOM is a memory device which can be written but never read...
