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, corresponding 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 knowledge constructions, scheduling algorithms, or digital circuits. As an example, in a print queue, paperwork are usually printed within the order they have been submitted.
This strategy affords a number of advantages, together with simplicity of implementation and equity in processing. It ensures that no component is indefinitely delayed or starved of assets, selling equitable distribution. Traditionally, this precept has been basic in managing knowledge circulate and useful resource allocation throughout varied computing and engineering disciplines, contributing to predictable system habits and lowered complexity.
