What do you mean by low latency access of data?
I am actually confused about the definition of the term "LATENCY".
Can anyone please elaborate the term "Latency".

Lower latency refers to a minimal delay in the processing of computer data over a network connection. The lower the processing latency, the closer it approaches real-time access. A lower latency network connection is one that experiences very small delay times.
Low latency in network connection refers to a minimal delay in processing computer data over the connection. Lower latency in the network provides closer real-time access with minimal delay times. High latency occurs when it takes longer for a packet of data to be sent to a physical destination.
Latency describes the amount of delay on a network or Internet connection. Low latency implies that there are no or almost no delays. High latency implies that there are many delays. One of the main aims of improving performance is to reduce latency.
While low latency and high bandwidth is the ideal to strive for, high latency has a deeper impact on load times than low bandwidth. At low latencies, data should transfer almost instantaneously and we shouldn't be able to notice a delay. As latencies increase, we begin to notice more of a delay.
The classic example:
A wagon full of backup tapes is high latency, high bandwidth. There's a lot of information in those backup tapes, but it takes a long time for a wagon to get anywhere.
Low latency networks are important for streaming services. Voice streaming needs very low bandwidth (4 kbps for telephone quality AFAIR) but needs the packets to arrive fast. A voice call on a high latency network results in time lag between the speakers, even if there is enough bandwidth.
Other applications where latency is important:
