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 system is analogous to a bodily queue, equivalent to people ready in line; the individual on the entrance of the road is the primary to be served. In computing, this will apply to knowledge constructions, scheduling algorithms, or digital circuits. For example, in a print queue, paperwork are sometimes printed within the order they have been submitted.
This method gives a number of advantages, together with simplicity of implementation and equity in processing. It ensures that no aspect is indefinitely delayed or starved of sources, selling equitable distribution. Traditionally, this precept has been elementary in managing knowledge move and useful resource allocation throughout varied computing and engineering disciplines, contributing to predictable system conduct and lowered complexity.
