1. Which of the following best defines a “system” in
the context of information systems?
A. A single software application that performs all
business needs
B. A random collection of unrelated components
C. A set of interrelated components working together
to achieve a common goal
D. Any network of computers connected to the
internet
Answer: C
Rationale: A system is defined as “a set of two or more
components that serve a common purpose and interact to
achieve a common goal,” matching option C. Options A
and B are incorrect because they either oversimplify or
mischaracterize a system’s collaborative nature; option D
describes only one possible form of system, not the core
definition (AIN1501 Study Unit 1 - P A R T 1
INTRODUCTION TO ... - Studocu).
2. An open system is characterized by:
A. No interaction with its environment
B. Unlimited storage capacity
C. Continuous interaction with its environment
D. Operating only on local hardware
Answer: C
Rationale: Open systems interact with their environment
(e.g., receiving inputs and providing outputs), whereas
closed systems do not. Option A defines a closed system;
options B and D are unrelated to openness (IPO model).
, 3. Which of these is a primary component of an
information system?
A. Legislation
B. Feedback
C. Furniture
D. Marketing strategy
Answer: B
Rationale: Information systems comprise components like
input, processing, output, storage, and feedback.
Feedback returns system output into inputs for continuous
improvement, making option B correct; options A, C, and
D lie outside the core IPOS framework (Components Of
Information System | GeeksforGeeks).
4. In the IPO model of a system, “O” stands for:
A. Operation
B. Output
C. Organization
D. Open
Answer: B
Rationale: In the Input–Process–Output (IPO) model, “O”
denotes Output, the result produced by the system after
processing inputs. Options A, C, and D do not correctly
map to the IPO terminology (Input, Processing, Output &
Feedback: Information System ...).
5. A closed system is one that:
A. Does not interact with its environment
B. Always has real-time data
