Latency is the time a single task takes from start to finish. Like measuring how long a motorcycle ride from home to work takes, it focuses on how soon one task is completed. section 1.2
Latency differs from throughput, which measures how many tasks a system handles over time. A bus can carry more people per hour than a motorcycle while taking longer to transport one person; greater throughput does not necessarily mean lower latency. section 1.2
