INTRODUCTION
The INFO 102 Introduction to Information Systems course is a foundational exploration of
the core concepts of information technology, computer systems, and the role of information
systems in modern organizations . This course equips students with an understanding of the
fundamental building blocks of computing: hardware, software, data, networks, and
algorithms. Students develop an appreciation for abstraction and how it simplifies complex
technology, explore binary representation and digital logic, and examine the anatomy of
computational devices from the CPU to memory and storage . Beyond technical
fundamentals, the course places information systems in a broader business context, covering
topics such as business information systems, organizational culture, and the strategic value
of data and technology . This question bank contains 200 advanced, exam-style questions
that mirror the content, difficulty, and format of the actual INFO 102 examinations,
integrating both technical and business-focused concepts. Each question includes a detailed
rationale explaining the correct answer and why other options are incorrect. With this
resource, you will identify knowledge gaps, build confidence, and develop the test-taking
strategies needed to succeed in this foundational course.
CORE DOMAINS TESTED
1. Foundations of Information Technology and Abstraction – Definitions of data,
information, and knowledge; the concept of abstraction and generalization;
operational attunement; mnemonic devices; information systems components .
2. Data Representation and Encoding – Binary and hexadecimal number systems (bits,
bytes, conversions), ASCII and UTF-8 character encodings, bit-mapped displays,
,2
pixels, metadata, the bit as the fundamental unit of information, and the
presence/absence representation .
3. Hardware Architecture – CPU, ALU, motherboard, RAM, ROM, BIOS, boot ROM, flash
memory, secondary storage (HDD, SSD), and peripherals; Moore's Law, computer
speed and performance .
4. Software and Operating Systems – System software vs. application software,
firmware, graphical user interfaces (GUI), desktop metaphor, the boot process,
software developers and interface design .
5. Data Structures and Algorithms – Abstract Data Types (ADTs), queues (FIFO), stacks
(LIFO), algorithm runtimes and complexity (logarithmic, linear, exponential), paging
and thrashing, the Halting Problem, intractable and undecidable problems, heuristics
.
6. Computer Networks and the Internet – Network components, intranets vs. the
Internet vs. extranets, Web 2.0, URLs (Uniform Resource Locators), and networking
media .
7. Information Systems in Organizations – Competitive advantage, transaction costs, IS
business cases, investment evaluation (Multi-Criteria Analysis), organizational
culture, and e-government .
8. E-Commerce, Business Models, and Digital Markets – Web 2.0 services, dynamic
pricing, Software as a Service (SaaS), social business, and customer/supplier intimacy
.
9. Information Security and Privacy – Confidentiality, integrity, availability (CIA triad),
encryption, PKI, and moral dimensions of the information age .

Q1: Suppose a character encoding uses 6 bits per character. How
many distinct characters can it represent?
A) 32
B) 64
C) 128
D) 256
Rationale: The correct answer is B. The number of distinct characters
that can be represented by a fixed number of bits is 2^n. Using 6 bits,
the number of representations is 2^6 = 64. Option A (2^5) is incorrect.
Options C (2^7) and D (2^8) are incorrect .
Q2: Which is larger: 17 or 0x17?
A) 0x17
B) 17
C) They are equal
D) Neither, they are both invalid
Rationale: The correct answer is A. 0x17 is a hexadecimal number.
0x17 = 116 + 7 = 23. 23 is larger than 17. The prefix "0x" indicates a
hexadecimal number in many programming contexts .*
Q3: Which is larger: 32 GB or 32 MB?
, 4
A) 32 GB
B) 32 MB
C) They are equal
D) It depends on the file system
Rationale: The correct answer is A. The prefix G (giga) means 10^9 or
2^30. The prefix M (mega) means 10^6 or 2^20. Therefore, 32 GB is
significantly larger than 32 MB. The difference is by a factor of 1024,
as a GB is 1024 MB .
Q4: Which of ALU, CPU, HDD, RAM, or SSD performs multiplication?
If several do, pick the most specific/focused answer.
A) CPU
B) ALU
C) RAM
D) HDD
Rationale: The correct answer is B. The Arithmetic Logic Unit (ALU) is
the component within the CPU that is specifically responsible for
performing arithmetic and logic operations, including multiplication.
While the CPU contains the ALU, the ALU is the most specific answer.
HDD and SSD are storage devices, and RAM is memory .
Q5: Convert the binary number 0b10101 to decimal.
A) 15
B) 17
