Throughput is the actual amount of data successfully transferred across a network during a specific period. Unlike bandwidth, which represents the maximum capacity of a connection, throughput reflects the real-world performance users experience.
For example, a connection with 100 Mbps bandwidth may deliver 85 Mbps of actual throughput because of network congestion, signal loss, protocol overhead or other factors.
