ITPEC IP April 2025 Question 15
ITPEC IP April 2025 — Question 15 of 100
A and D reduce system response time — they shorten communication and server processing after a request is submitted.
A faster client-server link reduces data transmission time, so A is relevant. A higher-performance server reduces the time spent processing the request, so D is also relevant. Together these reduce the elapsed time from the system receiving a request to returning its response.
Answer (b)
Why not others:
- B reduces a user's wait to obtain a client terminal, which occurs before the request and is not system response time
- C reduces the user's manual data-entry time, also before the request is submitted
- (a), (c), and (d) each include B or C and omit one of the two actual response-time improvements
Key rule: Separate human waiting and input time from response time, which consists mainly of transmission, queueing, and system processing after submission.
