What is listeners in JMeter?
A listener is a component that shows the results of the samples. The results can be shown in a tree, tables, graphs or simply written to a log file. To view the contents of a response from any given sampler, add either of the Listeners “View Results Tree” or “View Results in table” to a test plan.
What purpose is the duration assertion used for in JMeter?

What is latency in JMeter?
Latency is a difference between time when request was sent and time when response has started to be received. Response time (= Sample time = Load time = Elapsed time) is a difference between time when request was sent and time when response has been fully received. So Response time always >= latency.
