What does the term "throughput" refer to in a network context?

Throughput refers to the actual rate at which data is successfully transmitted over a network within a given timeframe. It is a measure of real-time performance and indicates how much data can be delivered from one point to another in a network, reflecting the effective data transfer rate that users experience.

This metric is important because it takes into account various factors that can affect the flow of data, such as network congestion, protocol overhead, errors, and the quality of the physical medium. Unlike theoretical data rates that a network might support, throughput represents the practical experience of users as they transfer files or stream data across the network.

Understanding throughput is crucial when evaluating network performance, as it provides insight into whether the network can meet the demands of applications and users. It helps in diagnosing issues, optimizing performance, and determining if the current infrastructure meets operational needs.
