Definition from the article :
Latency is the time required to perform some action or to produce some result.
Latency is measured in units of time -- hours, minutes, seconds, nanoseconds or clock periods.
Throughput is the number of such actions executed or results produced per unit of time.
This is measured in units of whatever is being produced (cars, motorcycles, I/O samples, memory words, iterations) per unit of time. The term "memory bandwidth" is sometimes used to specify the throughput of memory systems.
Bandwidth is the maximum amount of data that can travel through a 'channel'.
Throughput is how much data actually does travel through the 'channel' successfully.
Latency is the amount of time it takes to travel through the tube.
Bandwidth is how wide the tube is.
The amount of water flow will be your throughput
