Question
For an online transaction processing system, transactions per second is a measure of:

A. throughput.
B. response time.
C. turnaround time.
D. uptime.
Answers
Answer: A

"Throughput measures how much work is done by a system over a period of time
it measures productivity of the system. In an online transaction processing system, transactions per second is a throughput index. Response time is defined as the length of time that elapsed between submission of an input and receipt of the first character of output in an online system. Turnaround time is the length of time that elapsed between submission of a job and receipt of a completed output. It is a measure of timeliness in a batch system. The percentage of time that the system is available for processing is called uptime or a reliability index
thus, this is not the correct answer."   Your Comment
