ITPEC IP October 2022 Question 57
ITPEC IP October 2022 — Question 57 of 100
The complete sequence takes 223 seconds because automatic processing overlaps movement and other work. PC power-on takes 3 seconds, then its 150-second automatic login-screen startup runs until t=153. Walking, printer power-on, printer startup, and returning finish by t=126. After waiting to t=153, the user logs in for 10 seconds and the PC performs 60 seconds of automatic application startup: 153 + 10 + 60 = 223.
Answer (a)
Why not others:
- larger totals incorrectly add time that can overlap
Key rule: Build a timeline and add only sequential critical-path time; automatic device operations can run concurrently with movement or the other device.
