The primary performance measure for data storage systems is latency.Latency is defined as ____.
A)the time between when a request is made for data from a storage device and when the data is delivered
B)the time required for the BI system to finish analyzing specified data that is gathered
C)the difference between the time required to access data from memory and the time required to access data from a hard disk
D)the time between when the BI system finishes analyzing specified data and the time that resulting analysis is displayed on the monitor

Question

Quizplus · Accepted Answer

Latency is the time between when a request is made for data from a storage device and when the data is delivered. This is the primary performance measure for data storage systems as it impacts the overall speed and efficiency of data access and retrieval. Therefore, option A is the correct choice. Option B is incorrect as it refers to the time required for analysis rather than data storage. Option C is incorrect as it refers to the difference in time between memory and hard disk access, which is a related but separate concept. Option D is also incorrect as it refers to the time it takes for the results of analysis to be displayed, again a related but separate concept.
