The acronym describes a processing precept the place the primary merchandise to enter a queue, buffer, or stack is the primary merchandise to exit. This technique is analogous to a bodily queue, comparable to people ready in line; the individual on the entrance of the road is the primary to be served. In computing, this may apply to information constructions, scheduling algorithms, or digital circuits.

This strategy presents a number of advantages, together with simplicity of implementation and equity in processing. It ensures that no aspect is indefinitely delayed or starved of assets, selling equitable distribution. Traditionally, this precept has been basic in managing information stream and useful resource allocation throughout numerous computing and engineering disciplines, contributing to predictable system conduct and lowered complexity.
