INFORMATION SYSTEMS EXAMINATION
QUESTIONS AND CORRECT ANSWER WITH
EXPLANATION STUDY GUIDE
1. Question: What is the primary purpose of an Information System?
Answer: To collect, process, store, and distribute information to support decision-making,
coordination, and control in an organization.
Rationale: An information system is fundamentally a set of interrelated components that work
together to turn raw data into useful information for organizational functions.
2. Question: What is the difference between data and information?
Answer: Data are raw, unorganized facts, while information is data that has been processed and
organized into a meaningful form.
Rationale: Data on its own lacks context. Processing (e.g., aggregating, sorting, calculating)
transforms it into information that is valuable for decision-making.
3. Question: What are the five core components of a computer-based information system (CBIS)?
Answer: Hardware, software, data, people, and processes.
Rationale: These five components must work in concert for an information system to function
effectively. Hardware and software are the technology, data is the fuel, and people and processes
are the human and procedural elements.
4. Question: What is the role of a Database Management System (DBMS)?
Answer: A DBMS is software that allows users to create, manage, and access data in a database,
ensuring data integrity, security, and concurrency control.
Rationale: A DBMS acts as an intermediary between users and the database, providing a structured
and secure way to interact with large volumes of data.
5. Question: Define a "system" in the context of information systems.
Answer: A system is a set of interrelated components that function together to achieve a common
goal.
,Rationale: This definition highlights the key characteristics of a system: multiple parts,
interdependence, and a unified purpose.
6. Question: What is the difference between an open system and a closed system?
Answer: An open system interacts with its environment (e.g., takes inputs, gives outputs), while a
closed system does not.
Rationale: Most modern information systems are open systems, as they must interact with users,
other systems, and external data sources.
7. Question: What is a feedback loop in a system?
Answer: A feedback loop is a process where the output of a system is returned as input to modify or
control the system's future behavior.
Rationale: Feedback is essential for control and self-correction. For example, a sales report (output)
might show a decline, prompting management (feedback) to adjust a marketing strategy (input).
8. Question: What is the primary function of a Transaction Processing System (TPS)?
Answer: To record and process the daily, routine transactions necessary to conduct business.
Rationale: TPSs are the backbone of operational-level systems, handling tasks like sales, payroll, and
inventory tracking efficiently and accurately.
9. Question: What is the main difference between a TPS and a Management Information System
(MIS)?
Answer: A TPS focuses on processing daily transactions, while an MIS summarizes data from TPSs to
create reports for middle managers.
Rationale: TPS is operational and detail-oriented; MIS is tactical and summary-oriented, designed to
support managerial decision-making.
10. Question: What is a Decision Support System (DSS)?
Answer: A DSS is an interactive information system designed to help managers make non-routine
decisions by providing data analysis and modeling tools.
Rationale: Unlike an MIS, which provides pre-defined reports, a DSS is flexible and allows users to
ask "what-if" Questions and explore different scenarios.
11. Question: What is the primary purpose of an Executive Information System (EIS) or Executive
Support System (ESS)?
, Answer: To provide senior executives with a high-level, user-friendly interface for accessing
summarized internal and external information relevant to strategic decisions.
Rationale: EIS/ESSs are designed for the unique needs of top-level management, focusing on key
performance indicators (KPIs) and strategic trends rather than detailed transaction data.
12. Question: What is the role of an Enterprise Resource Planning (ERP) system?
Answer: An ERP system integrates all of an organization's core business processes (e.g., finance, HR,
sales, manufacturing) into a single, unified system.
Rationale: ERP systems provide a "single source of truth," eliminating data silos and improving
efficiency and collaboration across departments.
13. Question: What is a business process?
Answer: A business process is a collection of related, structured activities or tasks that produce a
specific service or product for a particular customer or customers.
Rationale: Business processes are the workflows that define how an organization operates, such as
order fulfillment or customer service.
14. Question: Define "e-commerce."
Answer: E-commerce is the buying and selling of goods or services using the internet and the
transfer of money and data to execute these transactions.
Rationale: E-commerce encompasses a wide range of activities, from online retail (B2C) to electronic
transactions between businesses (B2B).
15. Question: What is the difference between B2B and B2C e-commerce?
Answer: B2B (Business-to-Business) involves transactions between companies, while B2C (Business-
to-Consumer) involves transactions between a company and individual consumers.
Rationale: B2B systems often focus on supply chain management and bulk orders, while B2C systems
focus on customer experience, marketing, and individual sales.
16. Question: What is a "silo" in the context of information systems?
Answer: A silo is a system or department that operates independently and does not share data or
processes with other parts of the organization.
Rationale: Silos lead to inefficiency, data duplication, and poor decision-making, which ERP systems
are designed to overcome.
