To answer this question, we need to understand what throughput is and what measures can be used to quantify it.
Throughput refers to the rate at which a system or process can process or handle a certain amount of work over a given period of time. It is often measured in terms of the number of tasks, requests, or data processed per unit of time.
Let's go through each option to determine which one is not a measure for throughput:
A. Number of bytes transferred per hour - This option can be a measure for throughput. It quantifies the amount of data transferred over a certain period of time.
B. Number of reports generated per day - This option can also be a measure for throughput. It quantifies the number of reports generated within a specific timeframe.
C. Number of errors per hour - This option is not a measure for throughput. It quantifies the number of errors or failures that occur within a specific timeframe, but it does not directly measure the rate at which work is being processed.
D. Number of requests handled by the application per day - This option can be a measure for throughput. It quantifies the number of requests that the application can handle within a specific timeframe.
E. Number of hits per second - This option can also be a measure for throughput. It quantifies the rate at which a system or application is being accessed or hit by users.
Based on the above analysis, the correct answer is option C. The number of errors per hour is not a measure for throughput as it does not directly measure the rate at which work is being processed.
