The word "throughput" is a modern English compound, formed in the early 20th century by combining the common words "through" and "put." It originated in industrial and engineering contexts to describe the amount of raw material that could be "put through" a manufacturing process within a given time. The logic is transparent: "through" denotes the passage or flow of materials, while "put" implies the act of processing or producing an output. This literal combination evolved into the abstract technical term used today to measure the processing capacity or efficiency of any system, from computer networks to service industries.
