ITPEC IP April 2021 Question 14

Source exam: ITPEC IP April 2021Topic: System Component

ITPEC IP April 2021 — Question 14 of 100

A component that limits the performance of the entire system is a bottleneck. Even if other components are fast, overall throughput cannot exceed the capacity of the slowest constrained stage, so improving unrelated parts may yield little benefit.

Answer (d)

Why not others:
- throughput is the amount of work completed per unit time

- defragmentation reorganizes fragmented storage data

- a flowchart represents a process or algorithm graphically

Key rule: Find and improve the limiting resource first, because system performance is governed by its bottleneck.
